I get the “cheaper” version of Mr. Clean magic erasers and then to stretch them even further. Once I wet them… put a dab of dollar store baby shampoo on them to clean out the tub and sink.
Works like nobodys business!!! The shampoo works great at breaking down any buildup on the tub without alot of work. Saves me from breaking a sweat and tearing up my neat little sponge!
May be all in my head but, I swear it makes them last longer.
