That depends on what material your toilet is made of. If it is porcelain then you can clean with the same cleaners as home. If it is plastic, and it probably is, then do not use abrasive or harsh chemical cleaners. We use soft scrub on the plastic toilet, sink, and shower stall in our motorhome. Since space is often at a premium try to use a few basic cleaners instead of a whole bunch which you will have to find space for. We use the SS for countertops, plastic dinette table, and even the stove top and fridge.
