Leather Doctor® Kit-S3.ws, suede water-stain removal kit is design for water damage restoration. Most often, water damages from alkaline contamination manifest as stiffness and ring marks when dry. Suede is an amphoteric protein fiber and alkalinity influence shifts the protein fiber from ionic positive (+ve) to negative (-ve), thus losses the attraction between the ionic negative (-ve) non-amphoteric leather constituents like the tanning agent, dyestuff and the fatliquor. These entire ionic negative (-ve) leather constituents break hydrogen bond with the contaminated negative (-ve) protein fiber and move to form a ring edge. As the fiber is empty of fat and oil it becomes stick together when dry again. Restoration involves removing of surface soiling, recharging the protein fiber ionic positive (+ve), relaxing stiffness by penetrating and separating the stick together fibers, redistributing and even out the leather constituents from the rings and surrounding areas, and replenishing leach out fat and oil for suppleness and strength. The finishing includes nap exfoliation to a silky finger writing effect. The sequences of process includes the surface residue is brush with a brass suede Brush-3 and erase with suede Eraser-5. Cleaner-3.8 cleans and Acidifier-2.0 rinses with recharging the protein suede fiber ionic positive (+ve). Hydrator-3.3 works multi functionally when hydrating level and dwell time is fully optimize to work out stiffness, redistributing of the fugitive leather constituents and purging out foreign contamination. Fatliquor-5.0 rejuvenates and imparts leather with softness and suppleness when dry. Protector-S+ imparts non-stick surface to shield against sticky soiling and enhances the finger writing nap with a silky feel. Note: The mentioned product suffix number denotes its pH value in this holistic approach to suede water-damage restoration. The iso-electric point (pI) of suede averages pH 4, water averages pH 7. Between pH 7 and pH 4 there is an ionic difference of 1000 (one thousand) times. Foreign pH influences below the pI charges the protein fiber ionic positive while above the pI causes the protein fiber to shift ionic negative. The ionic leather constituents and the protein fibers behave like magnets, like poles repels and denaturing suede to rawhide. Cleaner-3.8 is replace with Degreaser-2.2 for degreasing as in Kit S5.dr. For fine lamb and kid suede, treat it as nubuck (Kit N3.ws) using nubuck Brush-2 / Eraser-4 instead.
Dry soil removal:
Note: Use the suede Brush-3 at a slant angle to avoid scratches on fine suede, otherwise use nubuck Brush-2 and Eraser-4 as found in Kit N3.ws
1. Remove surface soiling with suede Brush-3 and exfliolate nap with Eraser-5.
1. Clean with Cleaner-3.8 using suede Brush-3 and/or Eraser-5 and towel extract until it shows clean.
Rinsing and pH Balancing:
1. Apply Acidifier-2.0 saturating the entire surface for an even appearance, towel extract and allow natural dry.
2. Erase wick-up residue with Eraser-5 prior to hydrating.
1. Apply Hydrator-3.3, saturating the thickness of the suede to an optimum level with moisture oozing out when gently pressed between fingers and thumb.
2. Cling wrapped it for up to 72 hours dwell time with regular top up for redistributing the leather constituent.
3. Removes cling-wrapper and allow natural drying for foreign contamination to wick out.
4. Erase with Eraser-5 when crispy dry.
5. Inspect for satisfaction either repeat or proceed with fat and oil replenishing.
Fat and Oil Replenishing:
1. Apply Fatliquor-5.0 and redistribute with foam brush until saturation.
2. Repeat application each time water contents evaporate until fully saturated.
3. Allow natural drying for extra softness.
4. Erase wick-up residue with Eraser-5 prior to protection.
Non-stick, Rub-Resistant Protection:
1. Shake well, mist spray Protector-S+ evenly and brush-in, when dry brush re-nap for a finger writing effect.
Product Content and Description:
Leather Doctor® Cleaner-3.8 (250ml)
Cleaner-3.8 is a pH 3.8 universal anionic cleaner for all leather types that is particularly effective in emulsifying oily soils and in suspending particulates; 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 the fatliquor.
Leather Doctor® Acidifier-2.0 (250ml)
Acidifier-2.0 is a waterbased pH 2.0 leather acidifier for rinsing and pH balancing alkaline overexposure leather to a healthy squeaky-feel. It is to strengthen the ionic bond between the leather constituents like the tanning agent and the leather protein fiber from denaturing and reverting to rawhide.
Leather Doctor® Hydrator-3.3 (250ml)
Hydrator-3.3 is a waterbased pH 3.3 leather-safe hydrator. It is a fatliquor preconditioner with multi functional abilities. Surface application is primary to check for even surface tension free of blotchiness prior to fatliquor replenishing. Structural application will require saturating to an optimum level with moisture oozing out when gently pressed between thumb and fingers. The multi functional abilities include: a) to check for surface tension for an even appearance free from blotchiness prior to fatliquor replenishing. b) To plumps, relaxes and separates crushed, shrunk and stick together fibrils for manipulating away-unwanted creases and wrinkles. c) To rectify alkaline overexposure areas by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas. d) To activate the dormant dyestuff within the leather structure for color refreshing. e) To facilitates colloidal water movement within the inter-fibrillary spaces for wicking foreign soiling particulates to resurface. f) To stabilize, pH balance and charge the protein fiber below its iso-electric point (pI) ionic positive to hydrogen bond with the ionic negative fatliquor more effectively. This universal Hydrator-3.3 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin.
Leather Doctor® Fatliquor-5.0 (250ml)
Fatliquor-5.0, a micro emulsion of fat, oil and water is an anionic charged pH 5.0 fatliquor for rejuvenating all leather types. It relaxes coarse breaks, creases and wrinkles enhance suppleness and prevent cracking. It softens the leather 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 hydrogen bond attraction takes place between the fat and oil with the 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 Doctor® Protector-S+ (120ml)
This is a non-film forming, non-stick rub resistant protector that enhances a soft natural silky-feel with an unforgettable classic leather scent. It is for imparting a non-stick breathable barrier essentially to shield the detrimental effects of sticky soiling. Its natural silky-feel protection increases the leather resistance to wet and dry rubs, thus prolonging the characteristic finger writing effect of nubuck. Odorless version is available as Protector-S.
This is a 2½ x 2 x ¾ inch fine pumice block with corrugated side for effective nap exfoliation.
Suede Brush-3 This brass bristles detailing brush is ergonomically design to be an extension of our hand with sturdy grooved grip, designed to produce effective result easily and efficiently. It is recommend for split suede that provides tough, aggressive cleaning with mild abrasiveness; to reduce aggressiveness slant it at an angle especially for cleaning hair on hide. Length is 7 inches with a three-row bristle 1½ inches cleaning head.
3 inch Poly-Brush (1 pc)
