I’m shocked! WORKS SO WELL
I almost never leave reviews but I cannot believe how well this works!! We are new to having a boat and when the mildew stains started showing up, I didn’t know what to do. Tried a different brand and it didn’t work at all. $30 wasted. So I was skeptical that this would work. I’m soooo shocked - our vinyl seats look good as new! Spray it on, let it sit. The longer it sat the better it worked. I used a magic eraser boat sponge and scrubbed, but really, it was more about letting it sit and giving it time. I swear the stains continued to fade even after I was done! HIGHLY RECOMMEND.

Good cleaner for outdoor marine leather. Took a while to arrive, but then it did come from the USA. Quite expensive.
