You should note that while a single use (like to kill mould) may be fine, regular use on stone, metal or wood (i.e. most stuff in a bathroom) is not recommended because it is a powerful oxidizer that will considerably damage these surfaces if used regularly. That's because it releases hydroxyl radicals that destroy not only molecular bonds in stains and microorganism cell walls, but also attacks treated surfaces and corrodes metals.
