I am new( 1month) to Melaleuca products. The Sol-U-Mel is a wonderful product. I used it on a painting done on canvas to remove very strong moldy odors. from being stored in a damp basement. I first sprayed the back of the canvas with a light mist and let it dry over night. I repeated this process and then got brave enough to spray the front of the painting. The odors are completely gone and there was no damage done to the painting. I will continue to use this product.
