For best results, clean toilet bowl thoroughly. Separate blister from package and take the tablet out. Remove lid from the toilet tank and flush. When water is low, drop the tablet into the right corner of the tank away from the float assembly. Do not flush for 20 minutes so that the tablet can adhere to the bottom of the tank. When water is no longer blue, add another Bowl Fresh Blue Tablet.
Bowl Fresh In-Tank Toilet Bowl Cleaners inactivate minerals in hard water so the ingredients can loosen, disperse and suspend soils for removal. Use in toilets that are flushed on a regular basis or at least once per day.
