Amazing Product, never used anything better
This product is by far the best to use on boat seats I've ever seen or used. Looked horrible before, like new after use. Simple answer, just give it a try and you'll never buy anything else again. see photos!

Amazing!!
My wife told me we had to get rid of the boat because the seats were so ugly. I sprayed on Marine 31 Cleaner and without even scrubbing the mildew stain just disappeared. I thought it would take two days to clean the boat but I was done in four hours. My boat hasn't looked this good since 2000 when it was new. Thank you very much!!

Best product ever
If you have mildew on anything just spray this on you can watch it die and disappear. No work at all. It is like magic! Sprayed it on my mildew covered boat canvas and only had to rinse it off. Sprayed it on the boat itself, the boat seats and the house. It works. Don’t buy anything else

The best cleaner
This removed spots that were on my boat for eight years. I cleaned my entire 20 foot pontoon boat in about one hour, Just sprayed it on waited three minutes and hosed it off. You could just watch as the spots just disappeared. I had spent hours and at least ten different cleaners trying to remove the mildew spots on my light tan seats and couches.
Prosexcellent product

Couldn’t Believe My Eyes
The heavy black mold and staining covering our boat seating literally disappeared before my eyes. We tried everything to no avail, the mold would not come out of the tiny textures of the vinyl. This product removed it in three minutes and all I had to do was rinse! I really wish I had taken before and after pics! Definitely buy the gallon and spray bottle pack. If you have a lot of mold and seating it’s worth the money and you’ll need more than one bottle.

Does everything it says it does
We bought a used boat and the seats were very moldy. We sprayed on the mildew remover and watched the mold disappear like magic. We couldn’t be happier with the purchase.

Don't waste your money on this product. Go buy bleach. It is basically the same thing and will probably work better. Did not remove mildew from my Pontoon boat seats. Yes I followed all instructions.
Did not remove light to medium mildew stains from my pontoon boat seats. Did not even make a dent in heavy mildew stains. Based on odor I would say that product is nothing more than bleach that has been repackaged. Live and learn....
ProsNone
ConsExpensive and does not work well

Best stuff I've ever used!
I've tried everything over the years for the stubborn mildew on my boat seats. And having to scrub and spend hours cleaning the boat at the beginning of the season. Nothing compares to Marine 31 at all! I just sprayed it on, rubbed it in and let it sit for a bit and it took all the mildew right off!
Missouri
A wonderful product to use works better than anything that i have used in the past works great on above ground pools & vinyl seats
One of the best products i have ever used
Warrior River Alabama
Nothing better for mildew, mold and spider droppings.
This stuff is great for hundreds of applications. We use it on boats, golf carts and is great at removing green mold from concrete with absolutely no scrubbing. We live on a huge reservoir in the south where humidity abounds. This years during the "break out the summer toys routine" I demonstrated Marine 31 Products to my neighbors. They could not believe the fast results when cleaning Vinyl seats and boat tops. Spray it on, let it soak a few minutes, brush it and rinse it, DONE! Some neighbors have ordered others will be. GREAT STUFF.
Fabric and Vinyl Cleaner and Vinyl Protectant work well also.

Marine 31 Mildew Remover
I've been trying for the last five years to get the mildew off my boat seats. The year that my husband passed away I decided not to open the boat and uncover it. The next year when I uncovered it all of the seats and the deck were covered in mildew. I tried everything that I could think of to get that mildew off but it would not budge. That was five years ago and this year I discovered Marine 31. It was easy and extremely effective. The mildew is no longer even noticeable on my seats or my deck! It's like having a brand new boat again! I would recommend this product to everyone.
Key Largo, Florida
Great product
This product is perfect for removing stains off your boat. My boat was just about ruined from the white fly treatment spray from my neighbor’s yard. I applied the product on the seat cushions, scrubbed, and repeated. Cushions look new. I sprayed two squirts on the non skid, which was just about black, and let it set for a few minutes. Didn’t touch it. Sprayed it off, and it was white. The product is great. Use caution though, it will burn your skin,

Cumming, GA
works great, but packaging is faulty
Gallon container had been opened and 2 small strips of tape to keep closed. There was no sealed vinyl under the plastic cap. Not sure how much leaked out, but paper packaging was all wet.
GREEN BAY
truly amazing !
WOW, spray on, rub lightly, wait 5 mins. apply again if needed,wash off with clean water,LOOKS LIKE NEW ! I used on boat seats that were badly mildew stained I really didn't think that the stains would come out but totally stain free. Very easy to use, make shure to wear gloves, will cause skin to burn after about an hour or so .Great product that really works .

Best mildew cleaner EVER!!!
Was able to get 3 year old mildew stains out of my boat seats. Thought it would be impossible until I purchased Marine 31. Now they look as good as new.
ProsReally works
ConsNone

Great product.
Best mildew remover I've ever used, and I've use several different products. Easily removes
mildew stain from marine upholstery. Rather pricey when purchased in smaller spray bottles but
more reasonably priced in gallon containers, especially with a promotional discount applied.
ProsProbably the best mildew stain remover on the market.
ConsOther than price...none.
Miami
Amazing Product
It truly works as advertised. Surprisingly very little scrubbing.
Word of caution, if used inside a cabin or other confine area, make sure it is well ventilated.
ProsRemoves the most stubborn mildew stains will little or no scrubbing required.

Mildew remover Magic !
I have a wave runner cover I was close to throwing away because of all the mildew on it. I had tried several other products with no results, but then I came across several reviews of Marine31 and wanted to give it a try. This stuff is like a magician in a bottle. You can see the mildew disappear, and my cover looks New again!
