How can I clean rust from a bathroom toilet?

Products like Iron Out or CLR are widely available and work well. We use the spray form of Iron Out and it cleans the rust in our toilet very well.

You can also try a scouring stick if it builds up a ring.

Try The Works toilet bowl cleaner from the Dollar Store. It will also clean your tank from all rust that contributes to your bowl being stained.

Lysol Lime & Rust Remover Toilet Bowl cleaner, comes in a black squirt bottle. Scrub with Scrub Daddy or Mr. Clean Magic Eraser. If stubborn, use a scouring stick to scrub.
