Mold and Mildew Cleaners
One can remove mildew with bleach and several other caustic compounds. The real question is whether one irreparably damages the cushions, or discolors them, after using the product. Can anyone assure me that the treated seats are not damaged in any way? Thanks.
iv used it on my white and red vinyl seats no damage at allcleans good not great
I couldn't remove the mold with bleach. I was using this on a boat cover, very heavy material. I am not sure weather I strained the material from cleaning or it was the age and elements that did it in. I couldn't try it on the boat white seats as the product was shipped late into the fall season and we had already sealed up the boat for the season. We did leave the product in the garage and it did freeze, and was no good this year. Hope this helps.
I haven't had any problems with that, but do get real discoloration from gull droppings. The thing I also like about this product is that the mildew doesn't come back for a long time
Would someone please list the active ingredients of this product and if possible their percent of overall intent?
Best product I have ever bought for cleaning boat seats
Thanks, but with all respect that's not an answer to the question about ingredients. Can you or someone else state the list of active ingredients? Or is this just diluted bleach?
Is it safe to use on a Sunbrella-type boat cover?
Hi Alan,Although I have used this product before, I have not used the ones that Jamestown sent me. In the past I have used them on the inside of my Tahoe Black Bimini top. It does bleach it a bit, but it also works very well. Use a scrub brush and sun to help the process along.
will it work for sails? I have a spinaker that has some mold on it and if it can be cleaned will save having to replace the sail.thanks,Buzz
Ihave used it on surfaces and on vinyl with great results. I suspect it will work fine on a sail. It is a bleach base with soem other cleaners. I think it is worth trying, and my guess is that you will like the product
it cuts thru mold pretty good but not 100% still had some spots that would not come out
Limited Success With Removing Mold Stains
I've used this on a variety of items with limited success in removing mold stains. On my marine vinyl upholstery I've observed that this product will remove light mold stains well. For heavier "deep in" stains this product will lighten them, but not remove the stains completely. It does do very well on the undersides of my bow cushions where I tend to get mold staining quite often.This does work better at removing mold stains than any other product I've used, so I give it four stars.Where this product completely falls down is on the PVC fabric of my inflatable kayak. This product may kill the mold and keep it from spreading further (but I've also used some other products that may have helped kill the mold),but it does not remove even light stains.
Best Product I have ever used
I have tried so many products to get the mildew off of our Pontoon Boat Seats that I have spent a fortune. This product actally removes mildew within a few minutes with no elbow grease. It is truly amazing. It does smell alot like bleach so it should be used in a well ventilated area.
Makes mold dissappear!!

An Awesome Product
We have an '05 Bentley 20 cruise, white with brown and tan accents. We are in south louisiana so boating is great but the mildew is aggressive. Have tried many other products both store label and national brand, nothing....nothing works like this, my only complaint is it doesnt come in a larger size.
