Marine 31 Mildew Stain Remover Gel Gallon & 20 oz.

Marine 31 Mildew Stain Remover Gel Gallon & 20 oz.
Clings as it cleans!

Marine 31 Mildew Stain Remover Gel has a higher viscosity than the standard formula. This means that Marine 31 Mildew Stain Remover Gel won’t be pulled off the surface by gravity as quickly, giving it more surface time to do its business! As with any cleaning product, the longer Marine 31 Mildew Stain Remover Gel is on the surface, the more thorough the cleaning!

Marine 31 Mildew Remover Gel quickly and safely removes stubborn mildew stains on virtually all marine surfaces, including vinyl seat cushions, rubber fenders, fiberglass, Gel coat, canopies, and more! Marine 31 Mildew Stain Remover Gel forgoes volatile cleaners and instead relies on smart chemistry; even severe mildew growth is no match for the incredible cleaning power of Marine 31 Mildew Stain Remover Gel.

Marine 31 Mildew Stain Remover Gel is the best boat mildew cleaner available! If you’re a boater, chances are you’ve dealt with stubborn mildew stains on vinyl cushions. If you’re reading this product description, chances are you’ve been less than satisfied with the performance of other so-called marine mildew cleaners. Fortunately for you, we’ve compared Marine 31 Mildew Stain Remover Gel against other marine mildew cleaners and have found that it removes mildew stains faster, with less effort.

Not all marine mildew stain removes are created equal! Most over-the-counter marine mildew stain cleaners rely on heavy concentrations of bleach and other volatile chemicals that actually cause more harm than good. Marine 31 Mildew Stain Remover Gel removes stubborn mildew stains without discoloring, dulling, or drying out vinyl surfaces. Best of all, it still retains the powerful cleaning ability to remove mildew stains – FAST!

Use Marine 31 Mildew Stain Remover Gel on:
Vinyl cushions and chairs
Rubber fenders Fiberglass
Gel coat
Boat tops

Marine 31 Mildew Stain Remover Gel works wonders for household cleaning as well! Use this professional strength formula to clean tile, grout, showers, bathtubs, counters, and sinks.

Marine 31 Mildew Stain Remover Gel works FAST!

Spray directly onto surface and allow 1-3 minutes for penetration.
If necessary, agitate surface with a brush or terrycloth towel.
For stubborn stains, allow cleaner to penetrate for 5 minutes before agitating.
Thoroughly rinse and dry surface.
Follow with Marine 31 Mildew Stain Guard to protect treated surfaces.

Great product
Marine 31 Gel is the best product ever.
The spray is good but the gel is better on the vertical surface

Absolutely amazing!
As most people usually say, I'm not being paid in any way for giving this testimonial. I was recommended to use Marine 31 from a doc mate who said it would do a great job on the interior of my boat. My wife and I over the last 10 plus years have tried various products and nothing really worked. I had seen many YouTube videos on how amazing this product was and it did not fail to miss the expectation. I have a 1993 pontoon boat which had new interior put in 18 years ago. We applied the Marine 31 cleaner and were amazed how it looked after just one application. Because of the age of the interior we applied a second application and we're completely blown away at the results. Due to the age of our interior it is still not 100% but truly amazing at conservatively 90% restoration towards new! I have and would highly recommend this product for anyone to use! It is worth its weight and gold!
ProsMy next purchase will be the Marine 31 protector and sealant for the interior to keep it looking good.
ConsNothing negative to say about the product whatsoever. I would highly recommend that you read and follow the instructions on the back as you will need to wear some rubber gloves.
