So I bought a new (used) boat this fall. The original owner took immaculate care of this beauty...I mean for a 20 yr old craft, there's not a single scratch, scuff, or ding on the entire hull or interior fiberglass. The engine compartment you could literally eat out of. They took really good care of her...with the exception of the seat covers. The vinyl has really bad mildew stains from not being properly cared for. No idea why they overlooked this. But anyway....I have been able to remove quite a bit of it with old fashioned elbow grease, oxyclean, x14, scrubbing, and multiple washings/cleanings. There are still quite a few mildew spots/areas, however.

Does anyone have any way to clean these better? I'm about to resort to bleach and magic erasers, but I know this will probably cause more damage. Rather keep the original embroidered seat covers than replace with new. They're white btw.....any help appreciated. TYIA
