Gel formula clings for maximum mildew removal!

Nautical One Xtreme Mildew Remover was voted #1 mildew remover of 2020 and 2021! This viscous cleaner is formulated to cut through years of mold and mildew, leaving your vinyl seat cushions and rubber bumpers looking new. This thick, gel-like formula clings to vertical surfaces, allowing maximum dwell time so minimum agitation is required. Simply spray on, allow to dwell for a minute or two, and rinse off to reveal a clean surface. Use in conjunction with a brush for stubborn stains.

Nautical One Xtreme Mildew Remover works great inside and outside the house too! Stay away from BLEACH! While effective at removing mildew stains, bleach actually eats away at the vinyl, causing it to flake and peel over time. Even worse, bleach will destroy your vinyl seat cushion's stitching. Nautical One Xtreme Mildew Remover forgoes bleach and other caustic ingredients, instead relying on quality chemistry. Nautical One Xtreme Mildew Remover is not detrimental to the vinyl or the stitching.  What's more, you can also use Xtreme Mildew Remover on RIB boats!


Spray directly onto surface and wipe clean using an old towel. Stubborn stains may require agitation with a nylon brush after allowing 3-20 minutes of dwell time. After cleaning, remove residue with a rag or strong jet of water from a hose. Once the material is clean and dry, apply Nautical One Mildew Shield for Vinyl to protect the surface.

Best for mold/milder on boat seats

I've tried a lot of other products, but nothing got the stains out of my boat vinyl like this stuff does!

Bought a boat that had been covered for a few years. Opened it up, and everything was black with mold. Power washed it down, and the vinyl was horrible. I first used Starbrite mildew stain remover - didn't touch this stuff. Used their Ultimate Mildew remover - NO EFFECT. Grrr! Then I went to Purple Power and Clorox, my secret weapon against mold, and it didn't touch this stuff. I was surprised and a little shocked. Desperate, I went to straight Clorox in a rag, laid on a spot... Nothing! At this point, I figured this was a lost cause. But then, on forums, the Nautical One Extreme was being touted as a miracle. One guy after another started out skeptical, and then came back and said it worked. I was VERY doubtful, but I decided to try it before re-doing the vinyl in the boat. I've read some of those guys posts for years, and believe them. Once it arrived, I sprayed it on a spot, and was shocked when the black mold started turning brown almost instantly. WHAT??? CRAZY!!! I used the brush that came in the 2-bottle kit, and I watched the mildew fade to pale yellow. Excited now, I moved down the bench seat and applied everywhere, and agitated it with the brush. By the time I got back to where I started, those nasty, black, deeply ingrained mildew stains were GONE! It's been over a week, and I still can't believe it. I rarely ever "drink the Kool Aid," but man, this stuff is everything it's touted to be. Simply amazing. Saved me a TON of money. Highly, highly recommended! Yeah, looking at my post above, I sound like a crazy person, but I don't care. This is 100% truth. -Tony Hill, Fredericksburg, Virginia

Best product for stained boat seats I have ever used!

This was my second purchase of the Mildew Remover. The first seats were so bad that I was planning to have them redone. All I did was spray it on, let is set a little while, scrub with a brush and wiped off with a towel . A few really bad areas took a second coat, but that was only because the rest looked so good!. The seats look nearly brand new! Now I'm doing my "extra" cushions that I typically do not use on the boat (center console) just to make sure they are ready to go if we need them. So far, the exact same results. I HIGHLY RECOMMEND THIS PRODUCT! There is absolutely no reason to not try it.
