You can use mild detergents to clean vitreous china products as necessary. Avoid caustic-based cleaning products, as they will scratch and dull the surface.
Wipe any splashes of cleaner solutions from plastic or plated surfaces immediately.
Do not use cistern blocks or in-tank toilet cleaners, as they can damage the flush valve or other working parts.
Avoid using aerosol products on toilet seats, and don’t allow abrasive chemicals or cosmetics (e.g. fingernail polish or aftershave) to come in contact with the seat, as they can damage the finish.
