Tire Stains on Leather

May I ask again!

Please!

Do you know the number of days, the tire were in contact with the leather to achieve a stain like that?

I'm not sure how long it was actually in contact but it's been there for a couple of months now. I'll ask him next time I see him.

Thanks

I have tried to stain a piece of white leather, wetting it and placing a tire over it, check after 7 days yet only very slightly stain to conduct a proper removal experiment.

Using additional alkaline products without neutralizing it with a pH 2.0 acidifier may not be a good idea as it may weaken the leather finish, manifest as tackiness or brightness.

Gordon's idea of physical removing it may work depends on how deep it has penetrated the leather finishes. It is just like slicing a damaged apple - still depends how deep the damage is. For leather it's only about 0.02mm thickness before we reach the leather crust.

However, once physically removed the original urethane topcoat (Topcoat-72Matte) need to be refinish even though the colorcoat is still intact. This would be the ideal scenario.

On the other hand if it reaches the leather crust and the color coat is entirely gone. We have to bear in mind the finishing step with matching colorcoat as well (Pigment Micro-54).

Eventually, the stain has to go chemically or physically...otherwise it will wick up through the new finishes...that will brings us back to square one.
