Leather Doctor® Kit-Sr5.uk, sheepskin urine killer kit is formulated to decontaminate urine problems from denaturing into dry rotting. Aged urine is detectable with its characteristic ammonic odor. The presence of ammonic odor may indicate the shifting of pH value up to 10. The suede side will most likely feel sticky or slimy with wet finger testing it. This stickiness is a sign of leather denaturing to dry rotting. Browning discoloration is the result of alkalinity from the fermenting urine. Blacken discoloration may indicate migrating tanning agents and white powdery residue the migrating fatliquor (fat and oil). Dried surface is clean and pH balanced with CleanUrine-1.5 > Acidifier-2.0 system to rectify the browning discoloration prior to KillUrine-2.1 treatment. At this stage, the skin should feel squeaky after returning to its chemistry integrity of pH 3 - 5. Stiff leather is relaxed and sticks together fiber separated by Hydrator-3.3. The penetrated stain removing process continues with hydrating prior to fat and oil replenishing with leather scented Fatliquor.LS-5.5. The above are done to both sides and leave for natural dry to satisfaction. Final cleaning to the wool side is done with CleanWool-5.5 follows with RinseWool-4.0. The final phase is done with Protector-S+ to impart a silky feel and diffuse a classic leather scent. Note that the mentioned products suffix numbers denotes its pH value in this holistic approach for hair-on-hide urine decontamination process. This kit comes with reduced weight option to save on shipping thus all the 250ml concentrate ratio spray bottles has to be cut (mix) and filled up with distilled water prior to use
A - Dry Soil Removing: SuedeBrush-2 > SuedeEraser-5 > Vacuuming system: A1 - Dry Soil removal is performed first to the suede side by SuedeEraser-5 then follows by vacuuming. A2 - The reverse wool side cleaning continues in similar sequence with HideBrush-5 or a slicker comb then follows by vacuuming.

Content and Individual Product Description:
Leather Doctor CleanUrine-1.5 in 250ml with a pH value of 1.5 is a water-based urine restorative cleaner with an extra protonating or pH balancing function to revert the leather from denaturing back to rawhide or dry rotting. However, displaced original fat and oil will need replenished for suppleness. The shifting of the amphoteric leather protein fibers to ionic negative (-ve) from the fermenting urine weakens the ionic attraction between the leather protein fibers with the other ionic negative (-ve) leather constituents like the tanning agents that results in tackiness, dyes that bleeds and fatliquor into stiffness that leads to cracks.A holistic system will require Acidifier-2.0 as rinse, Hydrator-3.3 for dispersing and wicking soiling particulates from within the leather structure to the surface by a reverse-transfer technique with Towel-5 and Eraser-4 for leather and nubuck; and Eraser-5 for Suede. Replenishing the original fat and oil with Fatliquor-5.0 rejuvenates its suppleness. Application: 1- Dry soil removal prior to application with appropriate Brush-1 for leather, Brush-2 for Nubuck and Brush-3 for Suede in combination with Eraser-4 for leather and nubuck; and Eraser-5 for Suede. 2- Spray CleanUrine-1.5 and agitate with appropriate brushes and towel extract until it shows clean. 3- Spray Acidifier-2.0 and agitate with appropriate brushes and towel extract until towel shows clean. 4- Proceed with Hydrator-3.3 to relax and separate the stick together fiber structure and dwelling it up to 72 hours helps to redistribute the surrounding leather constituents back to the exposed areas. Towel-5 is recommended to facilitates “reverse-transfer” of wick up soiling particulates through the towel to be peel when crispy dry. 5- Surface is erased accordingly with either Eraser-4 or Eraser-5 to removed wick up soiling particulates. 6- Stiff dry leather is again hydrated with Hydrator-3.3 prior to fatliquor replenishing. 7- Fatliquor-5.0 commences topping-up the difference to 14% - 16% (fat and oil) when dry. 8- Leather is ready for further refinishing as necessary.
Leather Doctor Acidifier-2.0 in 250ml is a water-based pH 2.0 leather acidifier rinse develop for controlling absorbent leather denaturing into dry rotting in conjunction with CleanUrine-1.5 in urine decontamination system. As a standalone, it is use for pH balancing alkaline overexposure that manifest as browning, marks, streaks, brightness and tackiness. Application: 1- Spray direct sufficiently and agitate with appropriate brushes. 2- Towel extract suspended soiling until it shows clean. 3- To dwell 10 to 30 minutes depending on exposure severity and let naturally dry to see result. 4- Wick-up soiling is removed by brushing or erasing accordingly.
Leather Doctor KillUrine-2.1 in 250ml is formulated for all leather types. This is a pH 2.1 aqueous leather urine stain neutralizer with a strong sour odor for neutralizing the ammonia and alkaline phosphorus salt found in urine from “reverse-tanning” the leather into dry rotting. Sour odor will dissipate when completely dry. Preparation Cleaning: 1- Dry soil removal - use leather Eraser-4 for smooth leathers and nubuck; suede Eraser-5 for suede. 2- Remove the surface soiling first - use CleanUrine-1.5 follows with Acidifier-2.0 with appropriate bush agitation and towel extraction. Application: 1- Spray and saturate KillUrine-2.1 sufficiently deeper than the urine stain with help of brush agitation. 2- Dwell 10 to 30 minutes for chemical reaction then extract until towel shows clean. 3- Rinse until towel shows clean to a healthy squeak with Rinse-3.0. 4- Control bacteria activities with KillBacteria-3.7 an option in extreme cases. Optional: 1- Remove foreign contamination from within the leather structure – use Hydrator-3.3. 2- Rejuvenate to soften and strengthen leathers structure – use Fatliquor-5.0 or leather scented Fatliquor LS-5.5. 3- Impart a classical leather scent to mask the finish – use Protector-B+, D+, S+ or W+. Urine: Urine is a compound waste discharge, comprises of urochrome, uric acid and the ammonium salt to deal with. When deposited urine attracts the natural bacteria from the atmosphere and starts to ferments, a putrid odor will develop from the protein component of the urine and ammonic odor will develop from the ammonium salt. When ammonic odor becomes present, the pH of the contamination would have shifted to 10. Such high pH above the neutral average 3 to 5 of leather causes the amphoteric protein fiber to shift ionic negative (-ve); that causes the protein fibers to repels its other ionic negative (-ve) constituents like the tanning agent, fatliquor and dyestuff. Behaving just like the attraction of a magnet, like poles repel. When the leather constituent breaks hydrogen bond with the protein fiber, the leather starts to denature and revert to rawhide. A typical appearance of an aged or compounded contamination is a darkening effect from the fugitive tanning agents, a whitening effect from the fatliquor. Fugitive dyestuff or bleeding is only apparent from a white towel detection and yellowing from the urochrome. The denaturing or reverting to rawhide effect of the leather is further confirmed by tackiness or in worst-case sliminess in the present of moisture. The leach out fatliquor results in stiffness and fugitive dyestuff results in discoloration. A systematic sequence of decontamination approach includes surface residue removal with CleanUrine-1.5 (pH 1.5), and rinse with Acidifier-2.0 (pH 2.0) recharging the protein fiber ionic positive (+ve) and neutralizing the ammonium salt with KillUrine-2.1 (pH 2.1). Utilizing such a low pH treatment retards bacteria activities from off gassing putrid odors, a natural pH control without the need to use bactericide or fungicide for mold prevention. Therefore, urine is a type of soiling that will require a biochemistry approach to decontaminate it. Restoring the leather begins after decontamination with Hydrator-3.3, a pH 3.3 multifunctional product that has ionic positive (+ve) charging abilities, an active surfactantcy essential for foreign water movement within the inter-fibrillary spaces to redistribute the leather constituents and purging foreign contamination to resurface. This is the last of the wet cleaning process to remove suspended urochrome yellowish compound through visible white tissue paper as an extension of the leather in the wicking process as the leather dries naturally. Only then, without a trace of the urine stain that Fatliquor-5.0 (pH 5.0) replenishing commences. The emulsified fat and oil encased water molecule breaks free when hydrogen bond attraction takes place between the fat and oil with the protein fiber, leaving a breathing space essential for leather transpiration to function naturally. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another like millions of inter-connecting hinges with smoothness. One important unique characteristic of leather is suppleness with strength and much depends on the fatliquor, in this holistic approach to effective leather urine decontamination and restoration. For severe neglected cases with finishes damages as seen in this picture, refinishing commences after leather suppleness restoration.
Leather Doctor CleanSuede-4.5 in 250ml is a water-based leather-safe cleaner with a pH value of 4.5 formulated for all suede type. Including Napa-suede, split-suede and the reverse nappy side Nubuck and of all smooth leathers. It’s also safe on all natural and synthetic fabric lining excluding silk and rayon. It is an all-purpose leather-safe mild anionic universal cleaner without the potential side effects like rings and browning on sensitive leather. It is particularly effective in emulsifying oily soils and in suspending particulates. It works by penetrating, lubricating and suspending soiling safely and effectively through gentle chemical reaction, working in perfect harmony with all leather constituents that include the tanning agent, preservative, dyestuff and especially the fatliquor for a leather-safe cleaning experience. In a holistic cleaning system it is highly recommended to follow through with RinseSuede-3.0 to a healthy squeak thus prevents or ceases potential remaining residue from overworking. Application: 1- Identify, inspect, test and dry soil removal prior to application. 2- Shake well, spray and agitate with appropriate suede detailing brush and or Eraser-5 accordingly. 3- Dwell 10 to 30 minutes or before it dries for complete soil de-flocculation to occur. 4- Extract suspended soiling – use dry highly absorbent terry cotton towel. Rinse Remaining Residue free of suds: 1- Rinse to a healthy squeaky clean until towel shows clean – use RinseSuede-3.0. Note: For stubborn soiling, use Prep-4.4 before going into other specialty products from the Suede Leather Problem Solving Guide. Recommend: 1- To reduce stickiness when necessary – use Acidifier-2.0. 2- To hydrate stiff leathers – use Hydrator-3.3. 3- To soften and strengthen leather – use Fatliquor-5.0. 4- To impart a non-stick rub-resistant protection – use scented Protector-S+ or scentless Protector-S. Use Protector-W or W+ for the coarser split-suede.
Leather Doctor RinseSuede-3.0 in 250ml is a pH 3.0 water-based suede-safe universal rinse for all napa and split suede. It is to removes suspended soiling by towel extraction while neutralizing harmful alkaline residues and charging the protein fiber ionic positive simultaneously to increase the attraction between the ionic negative suede constituent like the tanning agent, dyestuff and fatliquor. End result should produce a squeaky feel otherwise proceed with optional Acidifier-2.0 to resolve any alkaline overexposure sticky or slimy issue.Appropriate Brushes: Use SuedeSplitBrush-3 for split-suede (always use this sharp brass brush at a slant angle to avoid scratches to fine suede). Otherwise use SuedeNapaBrush-2 to avoid scratches and for fine napa suede. Appropriate Erasers: Use LeatherEraser-4 for fine kid and lamb napa suede. Use SuedeEraser-5 for coarser split suede. Application: 1- Identify, inspect, test and dry soil removal prior to application. 2- Shake well, spray and agitate with appropriate brush. 3- Extract suspended soiling – use dry terry cotton towel.
1- Apply the Hydrator-3.3 and use a horsehair brush or equivalent to remove surface soiling and extract with a white cotton terry towel until towel shows clean. 2- Apply Hydrator-3.3 with the polybrush and let it absorbed into the leather structure - keep on apply as long as it get soaks in. 3- Use a cling wrapper to control evaporation and leave it there up to 72hrs or a shorter duration to soften up the leather structure. There should be a little moisture oozing out when press with fingers and thumb to have the hydrator at its optimum level during this dwell time - may it long or short. 4- When the leather structure is limp and soft, the cling wrapper is removed and wick-up soiling is extracted with towel until towel shows clean. 5- While still damp, Fatliquor-5.0 is applied with the same polybrush to be fully absorbed by the leather structure. In each application cycle 83.33% of the fatliquor water content needs to be evaporated. It is the fat and oil contents that are essential to supple up the leather, the fat plumps the leather and the oil lubricates for softness. When the last application pools on the surface will indicate sufficient absorption and ends the application. 6- The leather is left for slow natural drying and surface shine is removed with Hydrator-3.3 until any milky residue is removed off the surface. 7- The seat can be used immediately by placing a towel over it. 8- It is also recommended that the seat be used from almost dry to dry to produce extra softness to the leather with strength.
Leather Doctor Fatliquor-5.0 in 250ml is an anionic negative (-ve) charged micro emulsion of fat, oil and water for rejuvenating all leather types. It is typically used in conjunction after Hydrator-3.3 relaxing and opening up the fibrous leather structure. It softens the leather when dry with stretchability, compressibility and flexibility, while enhancing its rip tensile strength greatly. It is for replenishing the original fat and oil that diminishes thru sun bleaching, ageing, heat and alkaline overexposure or cleaning. On application, the water-encased molecule breaks free when ionic attraction takes place between the fat and oil with the leather protein fiber. The excess free water content wicks out leaving a breathing space behind for leather natural transpiration. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another smoothly like millions of inter-connecting hinges. Thus helps to keep leather at its optimum physical performance and prevent premature ageing. This universal Fatliquor-5.0 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin. Leather Approximate Quantity or Percentage of Fatliquor: The quantities of fatliquor (fat and oil) contents retained in the leather after an universal tannery fatliquoring process may varies up from 14% to 16% depending on the leather types and it usage. This percentage drops as the fat and oil content diminishes or leaches through ageing, water, heat or chemical overexposure. Leather rejuvenating or fatliquor replenishing is base on weight of the leather in relation to the percentage of remaining fatliquor. A simple calculation of percentage of fatliquor topping up requirement would be as follows: If the weight of the leather in question is 100gm and fatliquor (fat and oil) content meter reading is less than 1%. By applying 80gm of Fatliquor-5.0 to it will deliver an end result incremental of 13.3% fatliquor when dry as the 66.6% water contents evaporates. In the leather rejuvenating Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system, Hydrator-3.3 plays an important role by relaxing, opening up the inter-fibrillary spaces, facilitating and redistributing colloidal water movement, protonating and doing all the pre-conditioning work prior to fatliquoring including cleaning up any excess surface remnants to have a sticky-free surface. In practice with severe dryness the ratio for Hydrator-3.3 is 2 to 1 of Fatliquor-5.0. It works out to be approximately 160gm of Hydrator-3.3 plus 80gm of Fatliquor-5.0 to replenish a 100gm dry leather from less than 1% back to the original tannery up from 14% to 16% fatliquor content. In every bottle of Fatliquor-5.0 by weight content is comprises of 16.66% ionic negative (-ve) charged fat and oil, and 83.33% of water, the water content that encased the fat and oil molecule in an emulsion suspension when hydrogen bond with the ionic positive (+ve) leather protein fiber will break free and discharged clear from the leather structure to the surface. Instruction: 1- Warm-up and shake well to a full emulsion for better penetration. 2- Apply Fatliquor-5.0 and redistribute with foam brush until saturation. 3- Repeat applications each time water contents evaporate until fully saturated. 4- Drive remaining surface remnants free of milky fat and oil until it turns clear with Hydrator-3.3. 5- Allow natural drying for extra softness. 6- Suppleness of leathers is further stake or massage or flex accordingly with a little wet back with Hydrator-3.3. Caution: Insufficient fatliquoring (fat and oil) content may suffer cracking from staking, massaging or flexing. Tips: 1- When crispy dry, prior surface contamination/damages may darkens as soiling particulates resurface. 2- Removes soiling particulates with Eraser-4 for all leathers including nubuck and Eraser-5 for suede. 3- Stretching the darken areas lightly will also lightens the appearance. Frequent Asked Questions: Question- "I finally got around to looking at the instructions to begin to apply my Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 application. I must say, the instructions are quite extensive, a little confusing and I'm sure a lot that doesn't apply to my application. Again, I am trying to remove some wrinkles on a seat bolster in a car that is only 6 years old. So the leather I would imagine is the way it is from stress and not from age. Would you be able to tell me in simple, layman terms how you would recommend going about applying to achieve the results I am looking for? It would be greatly appreciated." Answer- With the Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system you may start with: 1- Apply the Hydrator-3.3 and use a horsehair brush or equivalent to remove surface soiling and extract with a white cotton terry towel until towel shows clean. 2- Apply Hydrator-3.3 with the polybrush and let it absorbed into the leather structure - keep on apply as long as it get soaks in. 3- Use a cling wrapper to control evaporation and leave it there up to 72hrs or a shorter duration to soften up the leather structure. There should be a little moisture oozing out when press with fingers and thumb to have the hydrator at its optimum level during this dwell time - may it long or short. 4- When the leather structure is limp and soft, the cling wrapper is removed and wick-up soiling is extracted with towel until towel shows clean. 5- While still damp, Fatliquor-5.0 is applied with the same polybrush to be fully absorbed by the leather structure. In each application cycle 83.33% of the fatliquor water content needs to be evaporated. It is the fat and oil contents that are essential to supple up the leather, the fat plumps the leather and the oil lubricates for softness. When the last application pools on the surface will indicate sufficient absorption and ends the application. 6- The leather is left for slow natural drying and surface shine is removed with Hydrator-3.3 until any milky residue is removed off the surface. 7- The seat can be used immediately by placing a towel over it. 8- It is also recommended that the seat be used from almost dry to dry to produce extra softness to the leather with strength. Question- "I have been keeping the zebra damp and applying fatliquor with distilled water the last couple of days...it is pretty sodden and now looking white when I brush the fatliquor solution over it which means to me that it is not sinking in any more...." Answer- Before any application of Fatliquor-5.0, the total existing combination of liquid content has to be reduced to about 25% through slow drying, thus have the capacity to received further Fatliquor-5.0 in a repeated cycle to accumulate a total of about 15% of fat and oil when dry. Question- "I presume I now need the hydrator to assist the fatliquor to be absorbed??" Answer- By adding further Hydrator-3.3 on a fully saturated hide does not help the Fatliquor-5.0 to be absorbed. It is allowing the excess liquid to evaporate allowing further Fatliquor-5.0 to be absorbed instead. Question- "It seems to be more fragile with being so moist should I let it dry out again in view of the fact the hydrator may not arrive until next week?? Should I then just massage the hydrator over the hide before attempting to use more fatliquor? Answer- Sounds like the hide is sufficiently relaxed, let the liquid content evaporate up to 25% dryness and begin introducing Fatliquor-5.0 once more in a repeated cycle.
