The O-Cedar steam mop does not require the use of chemicals or disinfectants in particular. When it comes to adding substances to a steam mop's water tank (in case there is one to use), make sure you pick them only according to the manufacturer's suggestions and instructions. When heated, some cleaning chemicals and disinfectants can release toxic fumes. Even if you can add cleaning products to a steam mop's tank, only do so by following the manufacturer's instructions to a tee.
