Has anyone used BKF for lime scale in a porcelain toilet bowl?

BKF says it can be used on sinks, baths, etc., but they don't mention
toilets.

Seems like it might be effective. We've had a problem and neither CLR
nor vinegar has not been helpful!

Any comments appreciated!

yes. it does work somewhat, but not as well as stronger acids.
