303 16 oz Mold & Mildew Cleaner Plus Blocker

I wish I would have known about this product back in 2018 when i first bought my pontoon boat. I have tried a number of products over the past 8 years and nothing compares to this, Period. I feel like I've tried them all. My only recommendation is to grab a small bottle of the 303 Aerospace UV protector when you are done to re-protect the vinyl. I'm sure others would work too, I just know the 303 aerospace was designed to be compatible with this mold and mildew blocker so that's what I use. Highly recommend that product as well for protecting the vinyl from the sun.

This product really works well. I would buy again.

Love the product...ordered for a friend as well and he loved it...he tried to re-order and had some problems but he really liked it too. It works...that is the main thing! Car, golf cart and even an outside rug.

I love it! It immediately takes off any traces of mildew without scrubbing. Any spider poop comes off easier after this has been put on also. I will definitely be keeping this on board!!

I've been a 303 Fabric Guard user for several years and am not aware of any other product that works as well. I used the new Mold & Mildew Cleaner + Blocker on my boat seats and was similarly impressed. Took very little elbow grease to wipe the mildew stains right off. I have not had time to test the blocker capabilities but am optimistic it works as claimed there, too. I'd recommend this product and will buy in the future myself.

worked very well on most areas. not vinyl seats or tub completely

Did not work. Should work better for the price. Will not order again.

I did not get the 303 Mold %26 Mildew 2-in-1 Blocker. I got the less expensive version without the blocker.

I didn't get what I ordered but was charged for the more expensive product. That's just ripping people off. Check your email. I'm sending the cheap stuff back.

I used this on my boat seats and it did not remove one speck of the mold. Do not buy this product for boat seat cleaning.
