This stuff is wonderful! We live in an older home and our main bathroom does not have a vent & we have to keep the door shut because of my out of control 2 year old. So, mold is a problem. I've tried everything! The directions say to spray it and let it sit for a few minutes and wipe off. Well, I sprayed it and got distracted and about an hour later I went to wipe it off and it looked like a brand new bathroom. It has been a while since I found a product I've felt like raving about. I love this stuff!
