Marykate Mildew Stain Remover

I have been using this product for at least three years, purchasing this product through our local marina to remove the light mold and mildew that comes with storing my boat over the winter months. Last year I left the area for one year and placed my boat in long term storage outside, my mistake. When I returned this year March 2012 and retrieved my boat from storage, then removed the boat cover it was covered with mold and mildew from front to back.I did not hesitate to purchase this product again. Light mold and mildew will vanish after a few minutes, then wipe with a damp cloth. I did have to treat my vinyl seats twice due to the highly concentrated areas of mold and mildew that existed on my seats.Packaging is not very good on this product however with Amazon, a roll of bubble wrap and a cardboard box. One Container was damaged and leaked during the shipping process.For some reason the sprayers failed during use and had to transfer the product into a different container for use.I am rating the product five stars, two stars for Amazon and packing and shipping.

Didn't remove all the mildew. It cleaned the boat seats ok but mildew still there after 3 applications. Gonna try another product.

It works as described but I could of mixed my own with bleach. Nothing special about it. Mix your own

My genius mechanic left the drain plug in our boat over the winter, and the cover leaked, so it filled with water. Mildew EVERYWHERE! Totally disgusting. We tried washing it off, but no dice. Tried a lot of stuff - no dice. We were just about to have the seats reupholstered and gave this stuff a last-ditch effort. Oh. My. Gosh. We couldn't believe it. The directions say to spray it on and wait for the stains to disappear. I was skeptical... until it worked! I wish I could attach pictures. So amazing! The mildew was so thick, but it disappeared. I used the entire bottle doing my whole boat (21 feet V-drive Sanger V210). Thank you so much for making this stuff!

My pontoon boat had been sitting covered for almost two years. When I took the cover off, it was so covered with black mold (on white vinyl) that I was sure the seats would have to be recovered. Some one recommended MaryKate Mildew Stain Remover. I felt it was a waste of time, but tried it anyway. I am amazed! My seats cleaned up great! After the first cleaning, the seats were so clean most people would not have felt they needed another cleaning. But, I am picky and wanted to see if I could remove the few light stains that remained. I let the seats dry completely and cleaned them again. They are absolutely mold and stain free. I used a vinly conditioner and they really look new!

This remover absolutely works as advertised! We have a pontoon boat that is covered and put in a shed and when it is taken out in the springtime it is completely covered with mildew. Just black! Nothing I have previously tried worked very well, only taking removing a small amount.The vinyl seats are white, so it shows up terrible! I sprayed the Mildew Remover on the seats and allowed it to soak in for about 5 minutes. Then wipe with a damp cloth and ALL mildew will be gone. It works best if sprayed and allowed to soak in direct sunlight.This product ABSOLUTELY WORKS!!!!!!!!

Great working product. This is the second bottle I have bought. Problem was this last bottle is it arrived about 30% full. Luckily it was in double bags and had not leaked everywhere. I was able to recover some, but still only had less than half of the 32 oz ordered. Since it is considered hazardous, it doesn't allow returns. Now looking how to get compensated for the undelivered amount.

I bought this on the strength of reviews I had read. Before it arrived I used a solution of Odo Ban on my boat seats and got very good results. My initial reaction is that the Odo Ban did a better job and was much cheaper. Will have to use this again to make a final determination.
