Q: Does the bottom of can rust if I leave it on the floor in the shower?

Great question. The bottoms of our can have a special plastic coating to make them rust-resistant, but they are not rust-proof. If the can is stored in a damp or moist place, it can rust over time. We do not recommend storing the can in the shower or tub. We suggest wiping the bottom of the can dry after each use and storing it in a dry place. -The Gillette Team
