General rules for toilet

This is the one surface in the house where a bleach based cleaner is the obvious and correct choice, because the hygiene question is real and the material tolerates it.

Deal with the visible mess first with paper and warm soapy water, then disinfect. That order matters here as everywhere else, and it also means you are not scrubbing at something while a disinfectant is working.

The seat, the hinges and the rim underneath are where the actual problem is. The bowl looks after itself.

Check the label

A toilet bowl is glazed china and tolerates a bleach based cleaner, which matters when the sickness came with a stomach bug. Bathroom suppliers warn specifically not to put bleach in the cistern, because it damages the internal fittings, and never to mix it with anything acidic.

Stains on toilet

A toilet is vitreous china, a plastic seat and a set of hinges, and only the first of those is easy.

The bowl is inert

Glazed china tolerates bleach, detergent and mild descalers, so cleaning it is a matter of choosing one and rinsing.

The seat and hinges are plastic

They scratch, they yellow with strong bleach over time, and the hinge recesses collect everything. Most seats have hinge caps that lift so the recess can be cleaned, which is worth knowing.

Bleach does not go in the cistern

Bathroom suppliers say so directly: it damages the internal fittings, which are rubber and plastic. In the bowl it is fine.

Never with an acid

Many limescale removers are acidic, and chlorine bleach with acid releases chlorine gas in a small room.
