Let the solution work it’s magic for about five minutes then flush the toilet. Now comes the dirty part--cleaning out the jet holes. With a piece of wire, scrape out each jet hole, using the hand mirror to make sure you get them all. After this you will want to clean around the jets with bowl cleaner and a scrubbing pad. Follow this up by pouring more bleach solution into the overflow tube.
If bacteria build up is a reoccurring problem, you may want to put a tablespoon of bleach into the overflow tube periodically. Never attempt to remedy the problem with in-tank cleaners. The chemicals they contain will deteriorate rubber parts in the tank, like the flapper or tank ball. They also negate any manufacturer’s warranty.
