Dirty Seat

Try some saddle soap......should remove it. If that don't work.....rubbing compound paste.

I had a seat like that on my JD 210 garden tractor. I tried everything, Fantastik, scrubbing bubbles, bleach, SOS pads, nothing worked. I tried Tilex® Mildew Root™ Penetrator and Remover because I read about it on a forum somewhere. It melted the stains right off without even scrubbing. I had been trying on and off for a year before that product worked for me. Make sure to get the exact product above as they also make a "mold and mildew remover" that I can't vouch for on those stains.

Thanks, I think I will start with Tilex and work from there as I think it is mildew as others have suggested.

Cheers,
