Roger,
I will try to get some pics for you. What I tried first was a product from Griot's Garage, which cleaned the surface well and took most of the stain out. But it appears the blue jean stain is embedded in the leather. I'm not sure which kind of leather this is in my 2012 Dodge Ram but I am assuming it is the coated and protected type I've read about and am unsure if your product will remove the stain without damaging the leather. Thanks for the reply.

Yes, I have read all of those. I'm just concerned that it wont come out because it's been on there about 6 months and I have scrubbed it with another product. A lot of money to try out!

Thanks, Jim.

In a blue jeans dye transfer situation, the stains are rubbed onto the surface grains while the lower grooves remains unaffected. A reverse transferring technique in reference to the red mark out pictures is executed in this manner.

1. Cut the paper towel from Kit Ap7.di fitting the size of this isolated stain areas.
2. Apply Prep-7.7 and saturate the paper towel before apply onto the isolated stain areas.
3. Squeeze out any air space so that the Prep-7.7 saturated paper towel becomes an extension of the leather surface.
4. Leave it overnight to see how the stains have response by peeling a corner to see the result.
5. Repeat a fresh application when necessary to further suspense the stain for a reverse transfer to the paper towel.
Note: A food cling wrapper helps prevents the dislodging of the application.

Lets see the result before the actual application.

Note that there are stitching rows, seams and perforated holes. Apply Prep-7.7 to the paper towel first then onto the leather surface avoids pushing unnecessary products into these weak points.

Picture of the test area – this test will give you a time frame, how long the stains will be removed better prepare for doing the entire dye stains affected areas in one go.

Leather Doctor® Kit Ap7.di, auto pigmented (perforated) 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. Prep-7.7. 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 Cleaner-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. 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+ 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.

Instruction:

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 stain 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 remove with repeat application.
4. To secure the test patch from dislodging wrapped it over with see through cling wrap.
5. When stain is removed with satisfaction, clean off the sticky residue with Cleaner-3.8 follows with Rinse-3.0 until a
squeaky-feel.
6. The lack of a healthy squeaky feel may be the result of worn out topcoat, reapplication with MicroTop-54M is
recommended.
7. Apply a soak out paper towel with Acidifier-2.0 over the area until dry to strengthen the finish prior to topcoat application.
8. When test after 72 hours shows poor response, Bleach-9.9 may be used to boost the Prep-7.7.

Mixing Ratio (1: 2: 2)
1. A mixing ratio guide 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
into a paste.
3. Hot water is dripped into the bottle using the pipette to activate the bleach and stirring into a creamy paste.

Testing with Bleach-9.9
1. Apply onto an inconspicuous or hidden area and leave it for a 12 hours inspection for discoloration.
2. Remove residue with damp wiping and cleaning sticky residue with Cleaner-3.8 follows with Rinse-3.0.
3. Cut out a paper towel, soak with Acidifier-2.0 and place on the test spot until naturally dry to neutralize the alkalinity.

Note
If testing with Bleach-9.9 bleach shows side effect, abandon and continue only with Prep-7.7.

Actual Application
Repeat testing successes to the actual application.

>>>Last night I applied the Prep-7.7 on the side of the seat. I covered it with the white cloth from the kit and covered the cloth with cling wrap as instructed. I left it applied over night, about 12 hours. When I took it off this morning there was no blue dye transfer on the cloth but when I wiped the stain with the cloth some of the stain showed on the cloth so it is coming off but not transferring as expected. I didn't have time to take pics this morning before work.
Please advise.

You may have not done it properly. The paper towel has to be press down and the Prep-7.7 has to show through, otherwise the suspended dye stain would not be able to wick through the paper towel. Please show pictures, if you are doing it correctly.


>>>I did not use a single layer so maybe that is the problem. I did this on the side of the seat like you showed so how do I keep it pressed down besides using the cling wrap? I can't stand there all night holding it.

If you apply enough Prep-7.7 and it does squeeze through the paper towel. The paper towel will stick there even on vertical panel.
Cling wrapping is place as a precaution. Please show pictures.


>>>Ok Roger, I'll do that tonite, I'm at work now. I will take a pic to show how I applied the 7.7. I will leave it applied over nite as before. If I can I will get a pic in the morning also of the results.

Jim, Waiting for your pictures - if done correctly the stains will be out soon. It is OK to squeeze through of the spot. but on areas that have needle hole, seams and perforated holes you want to apply the Prep-7.7 to saturate the paper towel before you lay them to stick on the stain surface. Do not push the Prep-7.7 into these holes, saving you time and effort to remove them. Roger

Tips:

Picture #5 shows a blotchy inefficient transfer of the blue jean dye is a direct result of loose contact between the paper towel and the leather surface as seen from Picture #1 and #2 application.

Pictures #3 and #4 show streaks of non-contact.

In comparison the above Post 2, Picture #2 example, the paper towel is soaks or saturates through and the paper is in direct contact with the leather surface without air space.

Picture #1 example below shows how the paper towel is further work with the help of leather Brush-1 for a close contact without air space that becomes an extension of the leather surface.

Picture #2 example shows the even “reverse transfer” efficiently - notice how tight the paper is in contact with the leather surface (as compare with the above Picture #1 & #2
