Leather Semi-Aniline Dye and Ink Stain Remover - Kit-Sa7.di by Leather Doctor 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 > Acidifier-2.0 system. It works by penetrating; lubricating and suspending the stains on dwell time and the Towel-5 reverse absorbs the stain instantaneously from the leather. The working of Prep-7.7 is to remove general soiling with better results from a longer dwelling time. The second process is to remove ink or blue jean or other dye transfer stains with CleanDye-7.9. Acidifier-2.0 acts as rinse and pH-balance both Prep-7.7 and CleanDye-7.9 back to the pH neutral of about 3 to 5 of the leather to a squeaky feel. Clean-3.8 > Rinse-3.0 system is for non-dye stain areas or for routine cleaning. Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system rejuvenates the suppleness of the leather. Hydrator-3.3 the first step is to relax stiff leathers prior to fat and oil replenishing as the second step especially the stitching needle rows with softness and suppleness when dry. MicroTop-54S is an option for renewing the finish from friction wear. Protector-B (scentless) and Protector-B+ (leather-scented) imparts 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. All concentrates in the bottles will need to be cut or mix with distilled water prior to use.
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 ink and dye stains are again further treated with a ‘reverse transfer’ technique allowing the CleanDye-7.9 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 CleanDye-7.9 residue with Acidifier-2.0 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.
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 a fresh application until the stain is gone.
3- Observe if there is a 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 an unsatisfactory result, proceed with CleanDye-7.9 testing over the existing spot.
Testing with CleanDye-7.9
1- Repeat procedure the same as above 1 to 4 with CleanDye-7.9.
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 accumulated soiling on all pigmented leathers. It works by dwell-time allowing it's superior penetrating, lubricating and suspending power to do its work. Rinse and pH-balance with Acidifier-2.0 until a squeaky feel.
Leather Doctor CleanDye-7.9 (60ml) - CleanDye-7.9 also is formulated for the removal of ink and dye transfer stains on all leather finishes type. It is mandatory to rinse and pH balanced with Acidifier-2.0 until a squeaky feel. This is a pH 7.9 waterbased high viscosity dyestuff remover that works by dwell-time allowing it's superior penetrating, lubricating and suspending power to do its work thus reduce unnecessary physical rubbing that may do more damages.
Leather Doctor Clean-3.8 (250ml) - This is a leather-safe pH 3.8 cleaner for routine cleaning
Leather Doctor Rinse-3.0 (250ml) - This is a leather-safe pH 3.0 rinse that follows immediately after Clean-3.8 to neutralize alkalinity if any 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 alkalinity. The effect of neutralizing is to reduce tackiness or sliminess from alkalinity and returning the leather to a healthy squeaky-feel. The objective is to return the leather to its pH neutral of 3 – 5 for the leather-structure chemistry integrity sake.
Leather Doctor Hydrator-3.3 (250ml) - This is a waterbased pH 3.3 leather-safe hydration with active surfactants for lowering the interfacial tension. It is for hydrating dried, stiffed or shrunk leathers to separates the crushed, stick together fibrils and relaxes them. 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 microemulsion fatliquor to rejuvenate leather with softness, suppleness, and strength. It is for replenishing original fat and oil that diminishes through sun-bleaching, aging, 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 aging.
Leather Doctor MicroTop-54S (120ml) - This is a satin finish 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.
Leather Doctor Protector-B (250ml) - This is a scentless (leather-scented version use Protector-B+), non-film forming, non-stick, a rub-resistant protector that impart a natural buttery-feel. Its non-stick breathable barrier is essential to shield the detrimental effects of sticky soiling. Its natural buttery-feel protection increases the leather resistance to wet and dry rubs, thus reduce stretch, scuff, and abrasion. It reduces friction squeaks that wear the finishes when one slides in and out of leather seats.
LeatherBrush-1 (1pc) - This horsehair detailing brush is designed ergonomically to be an extension of our hand with a sturdy grooved grip.

It is used for both dye and topcoat padding for smooth leathers. It is also used for reverse transfer ink and dye stains with CleanDye-7.9.
FoamBrush-3 (2 pcs) - This is a dense foam that resists tearing and shredding and carries more material. It has a solid wood handle that allows greater control for quality results. It is used for controlling and spreading fatliquor for more even distribution.
Sand-2000 wet and dry sandpaper (1 pc) - This sandpaper is selected especially for its ability to smooth rough finish. Sanding is aimed at the finish for better anchorage during refinishing. It is to smooth finishes in between coating when necessary. Sanding directly on leather unfinished surface is not recommended.
