Our toilets are actually porcelain so don't need to worry about scratches. I was more worried about clogging things, damaging things, or causing chemical reactions that I'm not aware of in a black water tank (which is a bit different from a sticks and bricks home toilet system). The bleach I bought is a 'green' bleach meaning it's chlorine-free so I used it, and all is good.
