Pigmented - Red Dye Stain - How to remove red dye stains from a white leather couch and maintaining on a regular basis from becoming grey with soiling.

[Questions!]

I have a white leather couch with red dye stains coming from a red bathrobe. I have had the bathrobe for about 2 months now so probably the stains are two months old. I purchased the product called Dry Cleaning for Suede & Leather and some of the pink left but not all. My white couch (see attached photos) is only 8 months old and it is in a sunroom that was added to my house just last spring. During the day you can still see the pink on the couch but I have a feeling it will not show up on the photograph. By the way I ordered the Leather Doctor Kit Sa7.di anyway because I will be using it often and of course now I have to condition my couch and add some protection on it. Your guidance with this is greatly appreciated. Also please provide me with instructions on how to maintain my couch on a regular basis so that the white does not become grey.






I have received your kit for the removal of ink and dye transfer and I thank you for same. I am looking forward to trying this so that I can get rid of a mild dye transfer from my red bathrobe onto my eight-month old white couch.

Now I am looking for a kit or products to clean my couch when stains appear almost on a daily basis. A white couch does get dirty quickly and I would like to maintain its gorgeous white colour. I saw you have two cleaners called “Light Soiling” & “Heavy Soiling” and I was wondering if one of these products remove any kind of daily stains. Also, where I sit I have noticed that the cushion is kind of grey and not that brilliant white so I would like to get rid of that.

Again, thank you so much for your help and I look forward to your next suggestions.

We will go through the issues as requested one at a time.

#1 “red dye stains coming from a red bathrobe”
Using the Leather Doctor leather-safe system Prep-7.7 > Clean-3.8 > Rinse-3.0 has proven many times over of its excellent result without side effect to the finishes (colorcoat and topcoat). However what we are doing is salvaging a fail attempt with unknown product “Dry Cleaning for Suede & Leather”. Dry cleaners have a high content of solvent and this might have removed the topcoat partially. This possible topcoat removal may drive the stain further into the colorcoat and hope is not the case.
In practice, if the stain is un-touch or original it is a straight process as follows:

Plan A:
1. Squeeze the Prep-7.7 onto the horsehair Brush-1 and apply by spreading and agitating the stain.
2. Stains release is extracted with absorbent towel until it shows clean.
3. Reapply and let it dwell up to 4 hours.
4. Suspended stains is extracted until towel shows clean.
5. Spray Clean-3.8 and remove with brush agitation the sticky residue for an inspection.
6. When satisfactory spray Rinse-3.0 and it is finish ready for Protector-B+, otherwise proceed with Plan B:

Plan B:
1. Apply Prep-7.7 directly onto the stain.
2. Lay paper towel and squeeze through the Prep-7.7 to saturate it.
3. Leave it overnight for at least 24 hours.
4. Inspect by lifting the paper to see if the stain is “reverse transfer”.
5. When it is satisfactorily absorbed by the paper towel, the stain removal job is accomplished and proceed to remove the sticky residue.
6. Spray Clean-3.8 agitate with Brush-1 and extract.
7. Rinse with Rinse-3.0 to a healthy squeaky feel, if sliminess persist spay Acidifier-2.0 to achieve a squeaky feel for leather pH chemistry integrity.
8. Proceed with Protector-B+ when dry.


Let see how this problem is solved before we go on to the next.

Leather Doctor Kit Sa7.di – Leather Dye / Ink Stain Remover Kit
Leather Doctor® Kit Sa7.di, micro-pigmented leather dye and ink stain removal 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 for micro-pigmented, antiquing and two-tone leathers that normally has a satin luster effect. The micro-pigmented and fashion effect varieties have a more delicate finish and is easily removed during stain removal and color refinishing is the norm on most wear areas. Prep-7.7 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. Remove sticky residue with Clean-3.8, rinsed with Rinse-3.0 and neutralized with Acidifier-2.0 when Bleach-9.9 is being used. Hydrator-3.3 relaxes stiff leathers and eliminates surface tension prior to fatliquor replenishing. Fatliquor-5.0 rejuvenates the leather structure with softness and suppleness when dry. MicroTop-54S 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
Note that secondary colors are delicate and color refinishing is the norm after stain removal on wear areas.
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 stains 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 stain is removed with satisfaction, clean off the sticky residue with Cleaner-3.8 follows with Rinse-3.0 until a squeaky-feel.
6. Apply a soak out paper towel with Acidifier-2.0 over the area until dry to strengthen the finish prior to topcoat application.
7. 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.

I hope you can see the difference between the wrinkle where it is completely white compared to the rest of the pillow.

The second photograph is my armrest where I was leaning into it I think you can see the pink colour.

Pictures are good enough, besides the color contrast of pink and grey, we see lost of coloring to the leather crust along the seam in picture #2. The removal-failed attempt from non-safe methods reveals the white grains (possible the raw colorcoat with missing topcoat while the grooves still remains pink. We will go into details how to prevent this from happening after we have done a test removing.

Instruction to reverse transfers the stain for a period of 72 hours.

1] Apply Prep-7.7 to the stain (about thumb size) and squeeze a cut out paper over only on the center and leave it there for 72 hours (Replenish the Prep-7.7 to keep it constantly saturated and change to a new paper if stains shows).

See this example:


Please show pictures if you have done it right.

[Questions!]

IT WORKED!!!

Please see the photos attached. One thing that got me a little worried is that when I cleaned it up with the Clean-3.8 and brushed it with the horse brush, there were little white granules loose. You can see these at the edge of the square. Is this normal?

Also, I am ready to do this to my armrest as well as my back pillow but I will not start anything until you guide me so that nothing turns grey like it did on my armrest. You had mentioned that you would say something about this after I finish the 72-hour patch test.

The first one is when I applied the Prep 7.7 Sunday morning and the 2nd one is the one I took this morning, 24 hours later. You can see the paper has a hint of pink. The paper stays wet with the product as per your request. You had also suggested for me to keep this on for 72 hours, keep it saturated with Prep 7.7 so I will send you another photograph tomorrow when it is going to be 48 hours after application of product.

>>> One thing that got me a little worried is that when I cleaned it up with the Clean-3.8 and brushed it with the horse brush, there were little white granules loose. You can see these at the edge of the square. Is this normal?

This is only normal if the initial topcoat is already damaged in some ways typical from unknown pre-attempt products that has weakened the finishes.
The MicroTop-54S, satin luster is the ready replacement after the leather is rinse to a squeaky feel with Rinse-3.0.


>>> Also, I am ready to do this to my armrest as well as my back pillow but I will not start anything until you guide me so that nothing turns grey like it did on my armrest. You had mentioned that you would say something about this after I finish the 72-hour patch test.

The armrest seam that turns grey as shown in Post #3, picture #2 is the loss of both the topcoat and the colorcoat that reveal the raw leather crust.
The entire folding seam is recommended to be repaired in this sequence: Adhesor-73 > Micro-54 > MicroTop-54S > Protector-B+ after the stains are removed.

Tips:
To avoid the Prep-7.7 from over working a 24hours inspection may suffice if the stain is already gone.
Avoid unnecessary physical agitation when using the horsehair Brush.
Use blotting motion for moisture extraction after Clean-3.8 and Rinse-3.0.
