Silica-Based Powdered Cleansers
There are many powdered cleansers on the market, and they clean well because they contain abrasives that scrub dirt and grime from surfaces.
Keep in mind that silica-based cleansers like Comet or Ajax will scratch porcelain, so you need to be careful where you use them. A nonabrasive powdered cleanser like Bon Ami, which is made of crushed feldspar, is gentle on all surfaces but still effective.
