Is there anything that may remove mildew stains, they are small round stains for the most part on a nice leather seat I just bought at a junk yard to replace my drivers seat, the condition of the leather is great, just some rain, mildew stains from sitting in the weather at the junk yard. By the way I have already tried the following with no success. If you guys don'tt come up with something for me then I am thinking about just redying the seat. Have tried:

Soft Scrub (non bleach formula)
Tilex Mildew Spray
Lexol Leather Cleaner
Woolite 5:1 ratio

 

Lysol maybe?

Given what you've already tried, it can't hurt, but probably won't work if something as strong as Tilex didn't. Good luck.

 

I'd try scraping it with a plastic knife.
