Marine 31 Mildew Remover Refill Kit

Marine 31 Mildew Remover Refill Kit
Keep mildew gone all year long!

Mildew is a constant struggle for those who own a boat. It will always rear its ugly head, even if you remove ever bit of it the first time around. So, you’ll probably need to remove it more frequently than you would like, and that requires A LOT of Mildew Remover. The Marine 31 Mildew Remover Refill Kit will provide you with plenty of Mildew Remover to get the job done several times over. You will also get the tools you’ll need to clean the mildew and a special funnel to make filling your spray bottle even easier!

Items in this kit:

Marine 31 Mildew Remover 20 oz. & 128 oz.
Marine 31 Mildew Remover 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 Remover 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 Remover.

Vinyl Scrub Brush
The Vinyl Scrub Brush is composed of gentle and soft Tampico bristles that are guaranteed to be gentle on any vinyl surface. The Vinyl Scrub Brush will work the product deeper into the minute pore of your vinyl, allowing it to penetrate and work more effectively than rubbing alone!

Black Edgeless Microfiber Towels
The Black Edgeless Microfiber towels are ideal for cleaning various surfaces. The edgeless design ensures that there is no unwanted scratch potential due to any flaws in the seams. The 16”x 16” size gives you enough surface area to have up to 8 working quarters when folded properly, but it is not so large that it becomes unwieldly. Because they are black in color, they will not show staining even after many uses in various cleaning processes.

Threaded Refill Funnel
Threaded Refill Funnels attach to most bottles ranging from 4 to 35 ounces, making it much easier to refill your favorite car care product from a larger half gallon or gallon jug. Use them once and you’ll wonder how you ever went without them! Since the Threaded Refill Funnels help prevent accidental spills, they should pay for themselves the first time you use them!

Kit includes
1 x 20 oz. Marine 31 Mildew Remover
1 x 128 oz. Marine 31 Mildew Remover
1 x Vinyl & Leather Scrub Brush
3 x Black Edgeless Microfiber Towels, 16”x 16”

Marine 31 Mildew Remover - BEST PRODUCT BY FAR!!
Marine 31 Mildew Remover is the best of its type! I have owned boats for 30 years and this product outperforms everything I have every used to combat mildew. This year we opened up a family owned boat that had not been uncovered for two seasons. The boat had been stored in a shady area with a full cover over the cockpit and bow covers. Once uncovered, there was mass mildew all over boat. The seats, cushions, dash and steering wheel were covered with mildew. The covers and top half of boat were bad also. After scrubbing attempts using several different products that I have tried over the years with no luck, the family was disappointed, even contemplating selling the boat at a loss. I came across Marine 31 products and figured why not, let's try. Miracle product!! Amazing!! The mildew melted away with zero scrubbing! Simply spray on, wait a few minutes, wipe away and then simply rinse with water. 100% of the mildew was removed. I truly wish I would have taken before and after pictures. Unbelievable success! During the next holiday family gathering at the water, I surprised everyone by pulling the completely mildew free boat up to the dock. Everyone was in disbelief that this product alone made the boat look new again. Several thought I must have had the entire boat reupholstered. I cannot say enough about the ease and results of this product. *** Read the label *** Not for fabrics, carpets or certain covers. It will "bleach out" fabrics... but will not harm colored vinyl. BUY WITH CONFIDENCE.
Prosease and results
ConsBleaches fabrics. There is a warning on label so be aware. Put down a drop cloth - do not let it drip on carpet. Success of product is AMAZING though, best product I have used in 30 years of fighting mildew and mildew stains.

Been waiting for a product that really works
We had black moldy spots on all of our pontoon boat seats.(For a few years) We literally tired everything to get it off. A friend told me they had the same problem and raves about Marine 31. I had my doubts but oh my goodness! It was truly amazing! Every bit just disappeared with hardly any effort. So glad to have finally found the answer. Have recommended it to everyone!! Don’t waste any more money on anything else.

Marine 31 mold remover
Product worked amazingly well. We did have an issue where the bottle was shipped in a box that was too small. The lid had come loose and half the product was in the bottom of the box and bag it was shipped in. We emailed the company that sent it but regrettably have not heard back.
ProsWorks amazing
ConsCompany that shipped did not do a good job with packaging and half the product was lost
Great Product
I use Marine 31 on my Seadoo, Boat and Golf Cart. Works Great.
Ventuta County, CA
It just works
For mild issues, it's simply just a spray and wipe job. When the scum gets nasty, just spray and let it sit for a bit, scrub and wipe. Pretty amazing stuff..

Worked better than anything we have used
The product worked just like advertised. We have had the seats of our 17 year old pontoon cleaned in the past where we store the boat in the winter. Did not do that this year so it had over a year or mold/mildew. Bought this based on the reviews and hoping for the best. It brought the seats back to almost new. Very little effort on my part. Spray, wait & scrub with brush, rinse & dry.

Miracle in a jug!
Marine 31 Mildew Remover is literally a miracle in a jug. It easily removes mildew from our pontoon seats and other components in less than 10 minutes. It cleaned our Bimini top with no issues (it was mildewed for years prior to us purchasing the boat). No bleaching out or discolorations. Super happy with purchase. One thing I'd like to address. The first gallon arrived damaged (leaked over half out). Customer service is fantastic. They replaced the gallon. That shipment was damaged prior to arrival, and yet again, they replaced. The way it was packaged this time, ensured the jug couldn't be jostled around, so we received the full product. Maybe some sort of seal under the lid would prevent future product loss. Will definitely order again.

Marine 31 mildew remover works outstanding
I have white interior in my Cobalt and this product made first of year cleaning so easy. Worked so easy, even sprayed on dock locker and rinsed off all mold was gone!
Marine 31 Mildew Remover
I've used it on the runabout vinyl seats and on sailboat non-skid. Magic on vinyl and mold gone on Gelcoat non-skid with a little bit of work.
ProsIt works!
ConsSmells very much like bleach...ruins clothes like bleach...may be bleach with an expensive marine label. Spray pump easy broke when refilling bottle. I ordered a kit and one item (funnel) had to be back-ordered; so, it took three and a half weeks to receive product. Not sure why they couldn't send the bulk of the order and back-order the balance.
Lake Greenwood SC
Works great!
This cleaner is amazing! Well worth the price because this is the only cleaner you need.
ProsWorks great with very little scrubbing required
Works well
Used this product on my recent reconditioning project. It has performed well. I tried many different types in the past but this one did the job. Only drawback is the strong chemical oder. Not good for below deck without a ventilation system.
ProsStrong product
ConsChemical odor can be overwhelming if not used outside or without proper ventilation

Marine 31 Mildew Remover Refill Kit
Was thrilled at the way this product removes mildew on our boat cushions. A friend gave us a sample, we tried it and ordered your product. We have also recommended it to several friends to try. Very pleased with the results.

The best
Bought a used boat. Broker said it will need cushions because of black mildew he knocked a lot of money off. I brought it home, bought Marine 31. in a matter of minutes the black mildew dissapeared.

Hot Springs Village, AR
Works as Advertized
A contractor working at my house said, "Sure, let me know how that works for you." When he saw the boat seats the next day, he asked for the name of the product so he could buy some, also.
ProsThis product works exactly as advertized. No scrubbing required, just spray on and watch it disappear in minutes.
