Magic in a bottle
We pulled our boat out of storage last week and all the vinyl was covered in mold and mildew. After 2 hours of scrubbing with mold and mildew remover and then trying a magic eraser - I was very upset thinking we would have to have the cushions recovered. The mildew had stained all the cushions and I couldn't get them to come off. I found this product online and figured I would try it before searching for someone to recover our seats. This stuff is MAGIC! I didn't even have to scrub the spots. It took awhile for the stains to disappear - but after about 15 minutes - every single spot was GONE! I will buy this product every year - and I am going to try the mildew preventer before we put the boat away at the end of the summer. HIGHLY recommend this product!!

Marine 31 Mildew Remover
Absolute wonderful product. For health reason, boat sat for two years in North Carolina's humid, moist weather. Was covered with canvas boat cover for 1 year. Last year sat out in elements uncovered. In effort to clean, I researched internet and decided to test four methods of removing mildew: 1) Marine 31; 2) 3M mildew remover; 3) comet spray gel (vinyl only); and 4) magic eraser. Applied all 4 products to boat platform, left for 5 to 10 minutes. Marine 31 results were unbelievable. Person that was helping me could not believe the difference in the results as compared to the others. Family and Friends that have visited, I take them out to see the boat. Also boat owners, they understand the effort and frustration in trying to removed mildew/mold. Needless to say, they have ordered the Marine 31 to clean their pontoon. The mildew//mold on platform was heavier, darker, and thicker than what is shown in the cushion pictures below. It was just the only items I didn't get cleaned before I ran out of Marine 31 and have reordered. A picture is included to show how great the platform looks now. Like New. It was only when I was reordering to complete the project (cushions shown) that I decided I had to write the review. So wish I had a before and after on platform. Writing reviews is out of character for me, BUT I had to let others know. I have invested too much time in previously cleaning our boat and by no mean got the results obtain with Marine 31. The Marine 31 actually removed the gray spots left from previous cleanings where mildew stain could not be removed. The boat is a Renken (oldie but goodie) with lots of wonderful memories. My excitement from using the Marine 31 Mildew Remover has given me such confidence in this Brand that I will be ordering their oxidation products.
ProsQuick, efficient, and does the job. Spray on, leave 5 to 10 minutes, wipe off Cleans much older (gray) mildew stains that were left when previously clean the boat (3 years ago)
Worth EVERY Penny - Order 1 to use and 1 to save for later
This stuff just flat works. After trying all the brands and nothing worked, including Mr. Clean Magic Erasers and 3M Mildew cleaner and scrubbing. I found a link to this online and ordered 2 bottles. We tried a hidden spot. My husband said, that will never come out. Wrong. Even the spots that were the worst, but hidden are gone. The seats are clean, clean, clean. No harm to anything. Thank you. We thought they were a lost cause. We used 1 bottle and now have a spare in the boat house, just in case.
ProsWorks as described. No harm to seats or surrounding carpet. They look brand new.

Very Good
The online videos show people spraying it on and wiping it right off and Presto! Completely clean. Nope. Gotta let it sit for a while then scrub pretty hard with a stiff brush. After a while you get the mold and mildew off but it still takes work. Also, the smell of this stuff is Strong! I think it is probably the better of the products offered out there...

Miracle Product
I never take the time to write reviews. However, this product certainly deserves one. My husband and I have tried every mildew remover product out there. Nothing worked. I came across this site online and read other's reviews. Decided to try one last product before giving up. This is truly a miracle product. One piece of advice---wait the 3-5 minutes after spraying. then use either a scrub brush or scrub pad. You will not believe the difference. to all you boaters---this is definitely worth the money. I just ordered the gallon refill jug to have on hand in the future. If your boat interior is bad with mildew, just order the gallon jug. You will use it up fast. It doesn't take off every little spec, but close to it.
ProsIt works!!!

Marine 31 Mildew remover
Most amazing product I ever bought. Tried everytning to clean the seats on an old neglected pontoon we bought last summer and nothing worked. I ordered Marine 31 Mildew Remover and the mildew disappeared like magic after spraying it on the seats. They look almost new. I’m going to order the rest of their products to keep the seats looking new and to preserve them.

Absolutely Unbelievable
I tried 2 other products to remove mold / mildew from my golf car seats, they didn’t work. I even used a “power brush” with these products thinking this would break it up. Not so lucky. Started looking online for replacement covers / seats to resolve my issue. My wife was also searching online for another type of cleaner when she came across a video of someone using Marine 31. In the video, it was hard to believe it was so easy to use and worked so well. We ordered some and It worked better than one could ever imagine. Sprayed it on, let it set for 3 minutes and wiped it off. UNBELIEVABLE, the mold / mildew was completely gone. I was amazed ! This product absolutely does what it claims to do, remove mold / mildew. I have already recommended it to a friend of ours who owns a marina, sending him a video of the results. Thanks Marine 31 for saving us both time and money.
We only ordered one bottle to make sure we were not wasting money on something that didn't work, because we had tried everything already. We will be ordering more, this stuff is amazing and it does everything it says. Our boat seats look like we replaced them with new ones, but all we did was use marine 31.

Marine 31
I purchased a large bottle of Marine 31 in June but did not use it until today Sept 28 as I winterize the boat. I am totally shocked at how fast this product made the mildew disappear. Four minutes I would guess with no scrubbing...I was floored. I spent the whole summer apologizing to my lake guests regarding this black mildew on my bimini top. I considered purchasing a replacement fabric for my bimini top this fall. Wow, wow and wow I'm overjoyed!
This really works!
I keep my boat on a covered lift but there is often condensation on the seats and they get mildew on them. I’ve tried lots of products and nothing worked very well until Marine 31. Wow! I sprayed it on, let it sit a few minutes and you can see the dark stains disappear. Just wiped it off and the seats look like new. I was actually considering having the seats redone but this saved me $3700.

Works as great
Product works great, however I do wonder how a product that requires gloves and That you have to avoid breathing in, can be environmentally friendly.

Are you kidding me!

Marine 31 Mildew Remover
I was amazed at how well this product worked. I had tried everything to remove the mildew from our pontoon vinyl seat. I let the product on for 5 minutes and then removed the mildew. I have already recommended it to two of our neighbors with boats.
ProsIt worked.
ConsA couple of spots remained but I hope to apply it again to see if I can remove them.

Works like a champ

Mooresville, NC
Great Product!
I had given up on being able to clean my pontoon seats. Last chance try with Marine 31 was a huge success. Ended up having to buy the galloon refill to finish the work. All of my slip neighbors were shocked at the results. They are all now first hand witnesses to your products performance.
Best for vinyl
Tried many other products. This was the best at removing stains without discoloration of the upholstery. Highly recommended
Works great
Removed all mildew in boat seats. Works as advertized
Marine 31 Mildew Remover is the BEST
Marine 31 Mildew Remover works better than anything that I have ever used to remove mildew from boat seats. Wish that I had known about this product sooner, it could have saved me many hours working to clean the boat seats. Other products that I used did not work nearly so well and required a lot more effort on my part.
This stuff is awesome. I didn't even need to scrub it in order to remove the black spots.
Athens, Georgia
Amazing product
I actually bought the marine 31 for my golf cart. Its been years since I cleaned the seats and they were really black from mildew. I tried many things but nothing worked. I almost gave up but decided to give marine 31 a chance and the results were unbelievable. I sprayed the front and back seats and by the time I was done spraying the back the front almost looked like new. I hardly had to even wipe them. I wish I would have taken before pics.. I got some after the fact and all I had to do was wipe them dry!
Southern Illinois
amazing product
After using everything I could think of to clean my pontoon seats with no luck I saw a comparison video with 4-5 products and marine 31 was the clear winner so I ordered it. Let me tell you it is amazing.Simply spray on seats and watch mildew get lighter, after 3-4 minutes hit stuborn spots with a soft brush, rinse off and towel dry. Get Marine 31 mildew remover, IT WORKS

No other product out there compares! We thought we were going to have to replace our boat cushions because nothing we tried would touch the black stains. This product is magic!

Best Cleaner Ever
Marine 31 is by far the easiest to use and best cleaner for vinyl boat seats I've ever found. It's a little pricey, but well worth every penny.

Miracle Worker!
Marine 31 works miracles. We had tried numerous other highly rated products with no success. Marine 31 removed the mildew black spots from our white upholstery completely! Our boat looks brand new! Well worth the money.
