Simple and easy! I use this outside my home on the wall with the least a mount of sunshine. Spray it on, wait about 10 minutes. Spray hose. Repeat maybe once more for really moldy areas. Done!

It really works!

Works wonderfully! Smell is not overwhelming. Gets rid of mold quick and easily. Works on painted walls and ceiling. Would definitely buy again.

It might be magic, but I'll take it.

I used this on extensive mold/mildew on the bamboo edging of my tiki bar. I figured I'd spray it all and then go back to the beginning and scrub it. Well, I got to the end and looked back and THE BLACK MARKS AND STREAKS WERE GONE! Totally gone. No trace of them. And they haven't returned. This stuff works better than anything I've tried, and I've tried a lot.
