Our cover sprung a leak and mildew grew quickly. This stuff is amazing, you spray it on and watch the mildew disappear. Made our seats look like new again. 4 months later, the mildew has not returned. Make sure to buy a good vinyl conditioner to apply after use, this stuff has a high bleach content and could break down the material. Boat seats should have UV protection applied regularly anyway, so i use a conditioner with uv protection in it. Attached before and after photos of two of the worst areas. ### ⭐⭐⭐⭐⭐ THIS STUFF REALLY WORKS!!!!! *by T***. on Reviewed in the United States on July 24, 2021* This stuff is amazing, I tried everything to get the mildew stains out of my pontoon boat seats and was very skeptical of this stuff. I read the reviews and decided why not give one more thing a try and boy am I glad I did. This stuff is like no other product out there. Simply spray it on, let it sit for five minutes, and watch it work. After five minutes just lightly wipe with a damp cloth to remove the loosened mildew and it's done, that simple. ### ⭐ Damaged the vinyl coloring on first use! *by B***R on Reviewed in the United States on November 29, 2020* Of course the jug doesn't list the ingredients but I can tell you that's it's nothing more than diluted bleach.It claims to be safe for [marine] vinyl but I can tell you that it took the color off the small spot that I tested it on. I used *maybe* a few drops of the stuff and the coloring ended up on my towel.Absolutely not safe for vinyl. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/84237350-marine-31-mildew-remover-128-and-20-oz-combo](https://www.desertcart.us/products/84237350-marine-31-mildew-remover-128-and-20-oz-combo) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-23*
