Ive had this spot on my audi s4 for ever now that always bugs me. It was there when I bought it used 2+ years ago. It looks like a spot of pink or red nail polish on the leather portion of the passenger side door. Up at the top.

Any ideas what I can use to get rid of it? or is it too late.

 

Autoglym Interior Cleaner usually does the trick for me.

 

Nail Polish
Removing nail polish from leather can be tricky and time consuming.
1. Dab off, don't rub, most of the nail polish using a paper towel. Then test the leather for colourfastness. This will help you determine if the leather can withstand the chemicals needed to clean it.
2. Take some acetone and dab an area of the leather that cannot be seen or is inconspicuous. Acetone is a non-oily fingernail polish remover. Wait a few minutes to make sure the leather does not change colour.
3. If the acetone damages the leather (I would imagine it will damage the polyurethane covering) you can try using isopropyl alcohol (IPA) test the alcohol first before using. Use a dabbing motion, do not rub.
4. If neither one of these methods work on your leather, contact a leather professional. They have access to more chemicals and should be able to remove the stain.
5. Always test the leather before trying any chemicals; if it is not tested, the leather could be damaged beyond repair.
