Great purchase
Did exactly what it was supposed to. I was liery at first bc I hadn’t heard of this brand and was nervous about hurting/staining the seats, etc. however after using the product and seeing the results, I have already made another purchase and it is now a common name and I will spread the word
ProsDoes exactly what it is supposed to do
ConsFollow the directions, that?s what they?re there for. **Leave on the recommenced time, if not you will see marks/stains

Removed the mold
It didn't take away the old Orange spots but, it did take away all the gray and black mold best product I've found yet to take care of the boat cushions and seats. Would recommend. I've tried a lot of products for boat cushions and this is by far the best.
Not happy with this product at all
The product didn’t take out much of anything. I tried letting it sit for different time intervals, wiping, scrubbing, etc. save the $ and just buy an off brand mildew remover, worked better than this. Also this took out some of the blue in the upholstery that it ran down onto, so now I have to have my seats redone.
Just works!
tried more then a few items with the same claim, nothing works as well as your Mildew remover. I use so much doing demo's for all my fellow lake friends
ProsQuick, easy, always works.
Consrinse off, and careful if it gets on your clothes. Has a bleaching effect.

Very disappointed
I am very disappointed... with myself for not knowing about Marine 31 Mildew Remover sooner. I could have saved myself literally hours of scrubbing, spraying, eating money on other products that just don't work like they promise. This is the real deal and does what they say. I am very happy with the results and have already sold a few new customers on this awesome sauce.
ProsVirtually effortless removal of mildew stains that I was unable to clean for several years. I started with my Captain's seat, which looked horrible, and said to my girlfriend "Here goes nothing. Let's see what this stuff does". I sprayed it top to bottom, set the spray bottle down and grabbed a cold beverage to give it some time to work. Literally within one minute we both looked at each other and said no way! It looks like it's half clean already. I'd be happy with half clean since I'd basically given up on ever seeing my nice white seats again. Within 3 to 4 minutes the seat looked like new. This is seriously good stuff.
ConsDon't buy the quart size to try. Just go big and get the gallon. I wish I'd done that but I was skeptical. I bought the quart and hadn't even finished before I went inside and ordered the gallon. I have a 24 for pontoon with standard seating. It was in bad shape and I ended up using right at 3 what's to complete the job, bow to stern.

1 year old Key West 219 FS. The upholstery was covered with mildew. I tried everything! Nothing I could think of would touch it...NOTHING. I gave this a shot and within 5 minutes the stains were gone. Impressive stuff!!
ConsExpensive but worth it!
Fort Lauderdale
Don't hesitate to buy!
I leave my boat in Florida for the summer months, somewhat unattended. I came back this year to mold on sun pads and rear seat.........nasty black, almost paint like, which seemed to be absorbed into the fabric. Tried expensive marine products.......no success. I took the sun pads off, planning to toss in the dumpster, but saved for pattern for a canvas guy to make new pads. Found a recommendation for Marine 31 online, and decided to try. I figured I was being scammed and would get some citrus based cleaner. Results: ABSOLUTELY AMAZING, I was smiling like a kid Christmas morning and started calling and sending pictures to everyone I knew. AWESOME product.
ProsNo heavy lifting whatsoever. Spray on, wait, wipe off.
ConsMy son, yacht Captain recommend sealing with an marine product after application. Say harsh chemicals could cause vinyl to crack????
Gulfport, MS
This stuff works just like the videos show. Spray it on, wait a few minutes, and wipe it off. Brings boat cushions back to life.

BUT--it definitely contains bleach. I ruined a pair of pants.
ConsContains Bleach
St Petersburg
Works as advertised
Immediately removed the mildew from my boat cushions. Very satisfied!
Prosdoes what its supposed to do
ConsDon't get it on any clothing that you don't want turned white.
