RMR-86M Marine Stain Remover, Professional-Strength Mold Stain & Mildew Stain Eliminating Cleaning Spray For Boats & Marine Surfaces, 32 oz

This deserves TEN stars!!!! Literally. I have a very nice tritoon boat (Avalon brand) with really nice , “luxury vinyl” seats. I had tried countless other products to clean the seats from the mold, mildew, growth etc, you name it, l tried it, and a few did work. But only with a TON of scrubbing and sweating and took multiple uses to work. This stuff, IS. MAGIC. PERIOD. lol. I don’t even know how to put it any other way. It says to spray it on and just rinse off. Which absolutely does work. However I just spray it onto a microfiber towel, and then wipe down the area, and INSTANTLY. And I do mean literally, instantly, not only does the mold and or mildew just vanish, the seats also somehow look like they’ve also been cleaned and conditioned. Like, they look brand new again. I paid a boat detailer $300 to do my seats, and he did do a good job, but no better of a job than this $20 bottle and 20 minutes of work did. This stuff is that good. Can’t say if it had a harsh or strong smell or not, as I wore a respirator just to be safe (probably was overkill,but it says to use eye protection and something about mouth yada yada) so I just wore my $30 Amazon full face respirator that also covers your eyes,. To be safe. I don’t write reviews all that often. But this is so worthy of a review. Many others have made similar posts about this, which is why I gave it a try. I didn’t think it was possible that it worked as good and as easily , as many of the reviews say, yet it sure as heII does. Pure magic!

I never write an Amazon review positive or negative. However today I used this to clean up some beach chairs that had mold and mildew on them. I bought them secondhand and figured since I spent so little on them I might as well give this a try even if the color faded. I should have done a before and after, but I didn't have the highest expectations and had no intention of writing a review so I don't have pictures. But holy wow! I had attempted to clean them with Dawn dish soap and scrubbing, and it removed just surface dirt. The chairs were wet when I sprayed them so I tested the spray on the shoulder strap and the color didn't fade so I just went for it. Once I sprayed on the product it took longer than "15 seconds," most likely upwards of 2 minutes but it was extremely fast and got every piece of mold and mildew and discoloration! The chairs seriously look brand new! I highly recommend this product. I was concerned about color fastness and had no issues with the canvas on the beach chairs. Interested to see if it affects the fabric long-term but I bought them so cheaply at this point I really don't care. I always gave up hope when materials had mold or mildew on them, but now this gives me hope that there is an alternative that could work. 10/10 recommend!

I wish I had taken more before and after pictures. I have a 2006 Formula 48 PC. I removed my winter cover and discovered some small black spots on my vinyl seating in the rear cockpit . I thought it might have been some type of mold but thought that the summer sun would kill it. I left the rear canopy top off for several weeks to expose it to the sun however it just seemed to get worse! That made me think that maybe it was mold and that perhaps the previous owner had used some vinyl paint spray on them. Thinking the paint was. Wearing off! I’ve only owned this boat for five years. Well I saw an ad on Facebook for a spray to remove mold from vinyl. The product was around $60 and I thought that’s expensive for something that might not work. That’s when I search Amazon for a similar product. Well I read the reviews saying it worked and invested way less than the $60 for the FB product . I sprayed this product on my seats and I was amazed that in the 15 seconds the spots were gone. The liquid sprays on clear and turns a little orange to brown color residue that washes off went hit with water. No scrubbing just rinse with water! Note: it did have a hint of bleach smell so I made sure to thoroughly wash off and areas with thread as I know bleach may damage the threads in seats. I am totally exceeding happy with this product. Again I wish I had taken more before and after pics but trust me it works. BTW I did try other cleaning product on the seats and the spots remained

This stuff is awesome, after I tried it on very moldy golf cart seats and it worked so well I made a second order. The speed in which it worked just as it said that it would. It did not bleach or change the color on the seats that I had and the are black and silver. There is no an offensive smell and the bottle did not leak. I will definitely buy again.

This works really good, and made the boat seats look good. The only problem I have is it has bleach in it.

This is one of the best cleaning chemicals to use to remove mold, mildew, or anything off outdoor seats. I used this on my Jetski to remove four year old mildew from the seats and it made it like new. Follow the instructions and within 15 seconds it will be gone. The smell it gives off is a normal mildew cleaner smell. But your supposed to wash it off afterwards. This product is easy to use, all you need to do is spray and boom, its gone. Its a very effective product which took all of the mildew off of all my seats that I tried it on as well.

This is some good stuff! Works great on boat! Cleans almost any my thing off! Highly recommend! Gets all the nasty stuff of white boats and seats, that other products can’t get off.

This stuff works miracles! So these pictures dont do it justice as they are the old seats ripped off my pontoon that I figured I'd put this stuff to the test. These stuff removes stains with ease. Great value. It does smell like bleach so be sure to use in a well ventilated area, I did all my work outside. These pictures I am posting were taken a 30 seconds after I sprayed. I did not use a brush or spend much time just a simple spray, and spray ... I will be using this a few times a year to keep the build up down. This products clears all mess's faster than any other product I've ever used.
