I have read how to properly clean a toilet. They always give directions on cleaning the bowl, but not the toilet seat and lid. Is it wrong to use the wet brush from the bowl and clean the seat at the same time, or does this spread germs? If I spray cleaner, like Clorox Cleanup on seat and use sponge, I feel like I should rinse with water, then dry. Then, shouldn't use sponge for any other purpose. Right? I want to avoid scratching plastic seat, or etching painted wood seats by using too strong of chemicals or too rough of cleansers.
