first time to use this cleaner. very easy to use; fool proof. worked great; my machine is totally clean-spotless, and gunk free. washer is 6 months old (new), and this worked great. smelled fresh, but not perfumed after cleaning. wiped interior clean after using, again very easy to use and will definitly use again. no residue left after cleaning, was spotless. :)
I didn't find that this made any difference once my washer started to develop a musty smell. However, 1/2 cup Borax in every wash load made a world of difference. I can cut my detergent in half and never have any musty smell in my front load Samsung washer.
I bought this a month ago and I am so happy that I did!
