Maybe not fun or glamorous but an acid based product will bust scum, remove rings and kill all of the bacteria along the way. If you have a tough ring you can use a nylon backed scrub sponge along with the acid cleaner. Another useful tip if you have a china toilet bowl is to use a pumice stone on stubborn rings and stains, just make sure to keep the stone wet as you work!
