This review is from: Ona Blocks - Natural Odor Neutralizer 175g Professional (Kitchen & Home)
Works like magic, used this in a damp cupboard and it killed off the mildew smell immediately. Now using same jar in a damp porch and it is doing a grand job. Remember that you will need to solve the root of the underlying smell though for a more permanent solution!
