A tenant has left me with a nasty cleaning job. I know I can use pumice, but it will scratch the colored finish and quite frankly I'm not sure if pumice is strong enough. I just ordered something called Rooto Corporation Industrial Toilet Bowl Cleaner. If it doesn't do the trick, does anyone know of anything else? I've already tried everything I could find in my hardware store.

The reason I don't automatically replace the toilet is because of the cost of labor and also the toilet is an unusual color that matches the sink and tub. I'd probably have to replace everything to get them to match.

Also, how do I fill the toilet bowl with water in order to soak the grime off? I never thought about this before, but it appears the toilet keeps the bowl water at a certain level.

Thanks.
