Product Description

Leather Doctor® Kit-Sa7.di, semi-aniline (micro-pigmented) andpigmented leather dye and ink remover kit is an innovative concept of removing blue jeans dye and ink stains featuring a “reverse transfer” technique utilizing a paper towel over the dwelling Prep-7.7 > CleanDye-7.9 system. It works by penetrating; lubricating and suspending the stains on dwell time and the paper towel reverse absorb the stain instantaneously from the leather. Prior failed attempt with set-in stains may require the help of Bleach-9.9 as booster to the Prep-7.7 to remove the residual stains. Clean sticky residue with Clean-3.8, rinsed with Rinse-3.0 and pH balanced with Acidifier-2.0 when Bleach-9.9 is cooperated. Hydrator-3.3 relaxes stiff leathers prior to fat and oil replenishing especially the stitching needle rows. Fatliquor-5.0 rejuvenates the leather structure with softness and suppleness when dry. MicroTop-54M is an option for renewing the finish from friction wear. Protector-B (scentless) and Protector-B+ (leather-scented) imparts a non-stick rub-resistant protection with a buttery feel that shield against sticky soiling and reduce friction noises. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe dye and ink stain removal system.


1- Accumulated Soiling Removal: 1a- Prep-7.7 is applied and agitated with detailing horsehair Brush-1; is then followed with terry cotton towel extraction until towel shows clean. 1b- Remaining soiling including ink and dye stains are again further treated with a ‘reverse transfer’ technique allowing the Prep-7.7 to wick trough the highly absorbent Towel-5 without any airspace. Towel-5 is work with Brush-1 until it becomes translucent without any white dry blotches. 1c- Inspect by lifting up the Towel-5 every 8 to 24hrs and up to 72hrs to see the result of the ‘reverse-transfer’ of stains. 1d- When 72hrs is up, peel off the ‘reverse-transfer’ and remove the Prep-7.7 residue with Clean-3.8 > Rinse-3.0 system to a healthy squeaky clean and let dry. 1e- Inspect for appearance satisfaction and proceed to Protector-B/B+ to finish or repeat the entire process with CleanDye-7.9 to remove the dye or ink specifically. 1f- Protector-B/B+ is applied to protect against ink and dye transfer.

2- Dye & Ink Stain Removal: 2a- CleanDye.7.9 is repeated through the above 1a to 1f steps and inspect for satisfaction.

3- Bleaching: 3a- Only in cases with pre-existing failed attempt with other products that may have set the stain, then Bleach-9.9 > Acidifier-2.0 system inevitably comes to use.

Note: Protector-B/B+ is skipped in the above sequence if color refinishing is the next option.

 Testing with Prep-7.7

1- Cut out a piece of paper towel from the kit not bigger than our thumb size and soak it with Prep-7.7.

2- Test it on the worst stained area and inspect every 24 hours with fresh application until the stain is gone.

3- Observe if there is sign of stain removal, if it does, the stain will eventually be removed with repeat application.

4- To secure the test patch from dislodging wrapped it over with see through cling wrap.

5- When 72hrs is up with unsatisfactory result, proceed with CleanDye-7.9 testing over the existing spot.

Testing with CleanDye-7.9

1- Repeat procedure same as above 1 to 4 with Prep-7.7.

2- When 72hrs is up with unsatisfactory result proceed with Bleach-9.9 + Prep-7.7 system.

Testing with Prep-7.7 + Bleach-9.9

1- A mixing ratio by weight is 1 part Bleach-9.9: 2 parts Prep-7.7: 2 parts hot water.

2- From the mixing bottle, a small test portion Bleach-9.9 is first added into the bottle follow with Prep-7.7 adding and stirring it to mix.

3- Hot water is dripped into the bottle using the pipette to activate the bleach and stirring it to mix.

4- Apply onto an inconspicuous or hidden area and leave it for 12 hours inspection for any discoloration.

5- Remove residue with damp wiping and cleaning sticky residue with Clean-3.8 follows with Rinse-3.0.

6. Cut out a paper towel, soak with Acidifier-2.0 and place on the test spot until naturally dry to neutralize the alkalinity.


If testing with Bleach-9.9 bleach shows side effect, abandon and continue only with Prep-7.7 > CleanDye-7.9 system.


Bleach-9.9 is only used on surface that pools, and not onto absorbent surface like perforated holes, needle holes or cracks. Avoid pushing cleaning products into the leather structure as well, otherwise will need to be neutralized with a heavy dose of Acidifier-2.0

Actual Application

Repeat testing successes to the actual application.

Preventive Care

Protector-B/B+ routine protection reduces unwanted soiling.

Kit Content and Product Description:

Leather Doctor® Prep-7.7 (60ml) - This is a waterbased pH-7.7 high viscosity leather cleaner developed to remove dye and ink stains on all pigmented leathers. It works by dwell-time allowing its superior penetrating, lubricating and suspending power to do its work. It is design to work in co-operation with Bleach-9.9 to synergize its working power. Sticky residue is to be clean with Cleaner-3.8, rinsed with Rinse-3.0 and neutralized with Acidifier-2.0 when Bleach-9.9 is in co-operated.

Leather Doctor® CleanDye-7.9 (60ml) - CleanDye-7.9 also is formulated for pigmented and all non-absorbent leather types. This is a pH 7.9 waterbased high viscosity dyestuff remover that works by dwell-time allowing its superior penetrating, lubricating and suspending power to do its work thus reduce unnecessary physical rubbing that may do more damages.

Leather Doctor® Bleach-9.9 (30ml) - This product is only use on non-absorbent leather finish types (avoid cracks, needle holes and perforated holes). This powder becomes pH 9.9 when works as a booster for Prep-7.7 in a weight ratio mix with hot water at a ratio of 1: 2: 2 (Bleach-9.9: Prep-7.7: Hot water). Non-metal tools are used to prepare the mixture. Sticky residue is to be clean with Clean-3.8, rinsed with Rinse-3.0 and neutralized with Acidifier-2.0.

Leather Doctor® Clean-3.8 (250ml) - This is a leather-safe pH 3.8 cleaner for removing Prep-7.7 sticky residue.

Leather Doctor® Rinse-3.0 (250ml) - This is a leather-safe pH 3.0 rinse to neutralize alkalinity and remove all traces of cleaning residue to a healthy squeaky-feel.

Leather Doctor® Acidifier-2.0 (250ml) - This is a waterbased pH 2.0 leather acidifier ten times stronger than Rinse-3.0 developed to rinse and neutralize Bleach-9.9 in this leather-safe system.

It is for charging the leather protein fibers below its iso-electric point positive for long lasting hydrogen bond with the ionic negative charged Fatliquor-5.0. It is for facilitating colloidal water movement within the leather structure during the wicking process to move soiling particulates to the surface.

Leather Doctor® Fatliquor-5.0 (250ml) - This is a pH 5.0 anionic charged micro emulsion fatliquor to rejuvenate leather with softness, suppleness and strength. It is for replenishing original fat and oil that diminishes thru sun-bleaching, ageing, heat and alkaline exposure or cleaning.
It penetrates and lubricates the leather fibers so that after drying they will be capable of sliding over one another smoothly.
It softens the leather with stretchability, compressibility and flexibility, while enhancing its rip tensile strength greatly. It relaxes coarse breaks, creases and wrinkles enhance suppleness and prevent cracking. It helps to keep leather at its optimum physical performance and prevent premature ageing.

Leather Doctor® MicroTop-54M (120ml) - This is a matte finishes waterbased soft polyurethane leather topcoat. It is lightfast and non-yellowing. It has excellent flow and leveling properties. It is recoatable and forms a flexible film coat. It gives good performing results from friction wear.
