We have a reoccurring issue with mold and/or mineral deposits under the rim of the toilets coming from the water holes (jets) that we haven't been able to completely clear out with a regular toilet brush and cleaners. Would Bio Drain gel help?
InVade Bio Drain probably won't be the best product to use in your situation. You can turn the water off to the toilet and flush it so that the bowl and the tank are empty. Thoroughly scrub both, paying special attention to the area under the lip of the bowl and the tank. While the toilet is drained, you can apply Invade Hot Shot Foam to the tank and the bowl and let it sit overnight to clean all of the cracks and crevices that you may not be able to clean properly. This process may need to be repeated a few times before you are able to get rid of all of the gunk that has built up over time.
