Camper canvas mold removal

Product works very well I ordered it a bit late in the season so probably will know more next season but like what I've done so far

Super clean

Cuts through mold and mildew on a boat cover and brings back the original color.

Highly recommend for Mildew blocker and cleaner

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!!
