mind: ceramic toilets are heavy, so lift with your legs, not your back to avoid injury, and if possible, have someone available to help with the heavy lifting.
squirt a bit of the lime removing cleaner into and around the toilet jet holes. let it sit for 10-15 minutes then use the stiff brush to clean out the hole. pour a bit of water over the area to rinse it off. if more lime remains, repeat this step.
