Is the method tub + tile cleaner safe on acrylic or fiberglass?
Yes, method’s tub + tile cleaner is in fact safe to use on acrylic and/or fiberglass as directed on the labels. As with all of our cleaners, the tub + tile spray is naturally derived, non-toxic and non-corrosive, meaning it will not damage, dry out or corrode common household surfaces. As a general precaution, we always recommend testing a small, inconspicuous area first when dealing with unsealed stone, painted or unfinished wood or any other surface you are particularly concerned about.
