I used Simple Clean Orgabic recently to do my master bedroom at my house. I have a baby and always am concerned with chemicals in my home and I am very sensitive to smells as well. I was very pleased that there was no strong smell or odor just a light fresh smell. One review on here said there was a white powder and I was nervous to see my outcome, but after vacuuming 3 times after my carpet dried I did not have any powder in my vaccine canister. We did the deep clean for my carpet that was it no added enzymes or anything like that. I was not only pleased with the lack of smell post cleaning but it actually took away the area on my beige carpet that gets horribly dirty from foot traffic of my husbands shoes. We will definitely be using this company again.
