Review on Rust-O-Less: Black 🦾 Large-Foam Sized Rust Prevention Solution by Donna Harvey

All right, does what it's supposed to, sits on the bottom of the shaving cream jar and prevents rust stains on the tub or wherever the jar is in the tub/shower. I have standard Barbizol lenses which are thicker and larger. Mine is a bit loose, I think if you take the jar and shake it that rubber thing might come loose from the jar but I can deal with that, just wish it was a little tighter. I thought of wrapping the bottom of the jar in duct tape or something but it wasn't worth the effort. I doubt they are made for this application as the rubber is very heavy and over the top, but someone figured out they might work and are selling them for it and wonder what else might work. I don't like rust stains from cans so a good product will prevent that.
