Bar Keepers Friend Spray and Foam Cleaner

Does this product work on tiled shower floor with lime build-up staining?

can this remove metal scratches from a plumbers snake on a toilet?

Seller: i'm confused. your photo shows 2 bottles of product, with a huge + sign between bottles. are you selling 1 or 2 bottles for price shown??

Will this clean an oven without leaving a strong smell?
