How do I remove the plastic bag a logo that was in bedded in my leather car seats. My car is brand new and I can't get it out. I tried rubbing alcohol, now Polish remover. Please help
Try different solvents on the bag to see what removes the ink. The try an effective solvent on an inconspicuous bit of upholstery to see if it damages it.
You might need to make a paste of the solvent and an absorbent material, such as diatomaceous earth (used in swimming pool filters), to keep the solvent in place and to wick away the stain.
Look online for other tips on leather cleaning, e.g. Bob Vila's site.
That's happened to me before and I used bug spray, sponge to scrub, and a rag to wipe off. It worked great.
You can try something like Goo Gone in a small area. But also check out available leather cleaners to look for something made for more than just regular maintenance.
I also own this attachment, which I use when applying cleaner / conditioner to leather. You do need a drill to attach it to.
If you don't plan / want to do any sort of detail work on your own, it's probably not worth investing in the product and any accessories, and instead just bring it to a good local detail shop.
