Every expert tool you need to say “goodbye” to mildew!

Mildew Remover Kit comes with every product and tool you will need to quickly and effectively rid your boat of the persistent pest that is mildew. Marine 31 Mildew Remover contains expert level cleaner agents that are specifically geared for eliminating a mess that is as stubborn as mildew.

The Microfiber Cleaning Cloths included in this kit make sure that any and all residue is wiped cleanly away and the surface is left looking pristine!

This will come as a shock to absolutely no one, but water is one of the most important factors in boating. Unfortunately, water also happens to be the biggest factor when it comes to the likelihood of mildew growth. This means that no matter how hard you try, mildew is going to grow on your boat surfaces. It’s unavoidable. When your boat surfaces inevitably become covered in mildew, it will take an extremely strong cleaner and an effective scrubbing brush to eliminate it. Luckily, this incredible money-saving kit has exactly that!

Does Exactly As Advertised!
I have bought so many boat seat cleaning products that claim to work. After watching a YouTube video of this one, I decided to try it. This is the BEST cleaning product I have ever tried and will be ordering the gallon size! Highly recommend!
Lake Thunderhead, Unionville, MO
This stuff is beyond amazing! Very little work involved. Spray it on and watch the mildew stains disappear. I have scrubbed the seats on our pontoon for years with many different products and nothing worked. We live on a lake and all our friends have boats. You should see an increase in sales just from all the people I brag about this product to! Highly recommend ??????????

We had a mildew problem on our tan pontoon seats. My husband was getting ready to store it for the winter and I stumbled across this product. It was amazing!!!! Cleaned all the mildew from the tan seats and they look like new!!! Highly recommend! I had to pay for expedited shipping as the boat was going into storage the same week and it was worth every penny! Great way to protect your investment!!

The "BEST" !!!
Prior to purchasing this product, I tried two others with NO results, none. I asked around for recommendations and was given Marine 31. This was going to be my last time to "order" a product. Once in came in, I went to the marina, read the instructions again, and began to try it on one of my vinyl seats. I was in disbelief!! It worked and it removed 99.9% of ALL the mildew stains on my boat. All of my seating on my 23' runabout look new. I highly recommend this product.
ProsQuite easy...spray it on, wait 3 - 5 min and wash it off!! In case of some stubborn spots, spray it again, wait 5 min, scrub it lightly with scrub pad provided and wash it all off. I will recommend you wash all of your seating afterwards with a mild soap. Then apply a moisturizer with UV protectorant.
ConsHonestly, I can NOT think of any.
Great buy
It works

SeaDoo seat
I had some stubborn black mold spots on my SeaDoo's vinyl seat. I tried everything for several years to no avail. I read the positive reviews online about this product and decided to try it. I was very happy to see that it actually does work. It removed 95% of the mold stains that had been annoying me for years. I'm going to see if I can get the last 5% as well with a subsequent application.

This really works. Best I've used. I tried all kinds of mildew remover and other cleaners including Clorox and it doesn't come close to this stuff. I saw an independent user review of it on Youtube and ordered as a result to try. Worth the money.

Truly Amazing
I decided to try this after 2 previous attempts with other cleaners and watching a YouTube video. Couldn't wait to get it, so I could try it out.. This stuff is amazing.. It literally took me 10 minutes to clean the seats and WOW!!! What a difference.. Can't wait to try more of their products. Marine31 customer for life now..
ProsEverything.. Best product hands down..

Marine 31 Mildew Remover
Just simply, this product works!. I used this on my boat interior and it brought the vinyl seats back to a fresh appearance. I used other products that did not help on mildew spots but this product worked like they said it would.

Best mildew cleaner...ever!
My boat is 19 years old and I have tried virtually everything to remove mildew from the seats with no luck. I came across a Jon Ulman video on YouTube that raved about this product and decided to give it a try. This product is amazing! My seats look brand new again! I wish I had found this product years ago.
Naples, FL
Awesome, worked like a charm in minutes!
I used another cleaner from West Marine on my Wave runner seat and had to scrub vigorously for over an hour until I got a decent result. This one worked in minutes with no scrubbing! Just wiped it off with a micro fiber towel and looks like new. I would definitely buy Marine 31 Mildew Remover again!
Oxford MI
I was skeptical as a marine company we test a ton of product for mold and mildew, some older boats we tell our customer they need to just replace or live with old mold stains. Came across this product and ordered waited a few days to start and was blown away. I am excited to save my customers $$$ on their boats.

ProsDoes what it says!
ConsStrong smell and it does dry chalky so the conditioner is a must after use.
