Coach Bag with Ink Stain from the Inside!

[Question]

I have attached 2 pics of the bag, from the inside (raw side) and outside.

The stains come from the inside, respond to alcohol-based agents, and come off as purplish.

I’m guessing they are pen ink, but could also be spilled nail polish? (Sorry I’m not the original owner of the bag)

The largest stains #1 and #2 have seeped through to the outside of the leather.

Hitting the stains from the raw side with either an alcohol agent or FatLiquor 5.0 followed by toweling would both result in color liftoff. (Does that mean the stain is oil-based?)

I would love to get your opinion and suggestion on removing as much of the stain as one can.

>>> The stains come from the inside, respond to alcohol-based agents, and come off as purplish.

Alcohol-based agents are not recommended as you can see the side effects of the surrounding areas dye faded.

Alcohol-based agents are too aggressive as they also remove the original fat and oil leaving these faded areas dry rotting, stiff, premature aging, and cracks eventually.


>>> I’m guessing they are pen ink, but could also be spilled nail polish? (Sorry I’m not the original owner of the bag).

Yes, with a closer look, it must be from a ballpoint pen.


>>> The largest stains #1 and #2 have seeped through to the outside of the leather.

Work from the suede side is recommended for the majority of the removal.


>>> Hitting the stains from the raw side with either an alcohol agent or FatLiquor 5.0 followed by toweling would both result in color liftoff. (Does that mean the stain is oil-based?)

Ballpoint ink is a compound stain that comprises a grease component and a dyestuff component. Yes, ballpoint ink is an oil-based stain.

1: What is the Ballpoint Ink and Dye Stain Removing 5 Products System?

1.1: Ballpoint ink is a compound stain that consists of a greasy component and a coloring dyestuff. Thus the need for Ink Remover 4.4 and Dye Remover 7.9 to work in tandem to completely remove both the grease and the dye component one after the other.

1.2: Ink Remover 4.4 a.k.a. Prep 4.4 works by penetrating, lubricating, and suspending the greasy component of the stains on dwell time, and the Towel 5 absorbs the suspended stain instantaneously from the leather.

1.3: Dye Remover 7.9 follows after the grease component is removed and works by penetrating, lubricating, and suspending the dyestuff component of the stains on dwell time, and the Towel 5 absorbs the suspended stain instantaneously from the leather.

1.4: Cleaner 3.8 removes sticky residue after successful grease and dye stain remover with brushing and towel extraction until the new folding side towel shows clean.

1.5: Rinse 3.0 rinses after Cleaner 3.8, with brushing and towel extraction until the new folding side towel shows clean.

1.6: Acidifier 2.0 pH balances leather to a healthy squeaky fee with brushing and towel extraction until the new folding side towel shows clean.

2: What is the Hydrating and Fatliquoring 2 Products System?

2.1: Hydrator 3.3 is a multi-functional product and the emphasis here is on deep rinsing and relaxing the leather before fatliquoring.

2.2: Hydrator 3.3 with its surface active agent penetrates deep into the leather structure and moves suspended staining particulates to the surface to be towel extracted.

2.3: Hydrator 3.3 hydrating and relaxing attributes are spread and distributed into the leather structure to plump, and suspended soiling particulates are towel extracted until the towel shows clean, and the leather is ready for effective fatliquoring.

2.4: Fatliquor 5.0 with its ionic negative (-ve) charged micro-emulsion of fat and oil is applied and spread over following the path of hydration without a dry edge.

2.5: Fatliquor 5.0 application cycle is repeated each round the water content resurfaces.

2.6: Fatliquor 5.0 last application ends when the product remains on the surface and is left for a slow natural drying.

2.7: Fatliquor 5.0 sticky residue is removed with Hydrator 3.3 until the milky residue turns crystal clear, and is left for slow natural drying.

2.8: Appearance is inspected, and any darkening effect is deep stretched with a tablespoon to satisfaction.

3: What is a Topcoating System?

3.1: Aniline Gloss Topcoat 21G is applied after a dry preparation to remove any surface soiling, by brushing and or erasing.

3.2: A light coating with a pad for the first coating will ensure proper adhesion and any surface residue removed followed by subsequent fine application with varnishing brush or airbrushing for professional results.

3.3: A fine 2000-grit sandpaper may be used in between dry applications to improve a smooth feel and is ready to protect it.

4: What is a Non-Stick, Rub-Resistant Protection System?

4.1: Protector B is applied and spread with Towel 5 to impart a nonstick surface against sticky stain and reduce friction rubs, and is ready for use.

5: Testing Tips?

5.1: Towel 5 is cut to a size not bigger than our thumb and soak it with Ink Remover 4.4.

5.2: When ink stain is through the reverse suede side, test and work on the suede side to avoid any distortion to the smooth leather finishes.

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

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

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

5.6: When 72 hours are up with unsatisfactory results, proceed with Dye Remover 7.9 testing over the same spot.

5.7: Dye Remover 7.9 is highly recommended for surface cleaning to reduce side effects.

5.8: Dye Remover 7.9 is transferred to Towel 5 or a cotton bud and the surface is wiped repeatedly to pick up suspended dye stains to satisfaction.

5.9: Cleaner 3.8 is applied to remove sticky residue by brushing and towel extraction until the new folded side towel shows clean.

5.10: Rinse 3.0 is applied to remove all remaining residue by brushing and towel extraction until the new folded side towel shows clean.
