You just pour in a cup or 2, making sure to get some of it around the rim. Let it sit and work, then flush.
Pour a full can around the rim so that it fully coats the bowl, then let it sit for at least an hour to allow the acids in the soda to break down the stains. Scrub with a toilet brush, then flush
I've always left it in over night (except when my husband flushed the toilet buy accident!) - I've found it really does work.
Hello there, Leave it in all night before you flush it again.............Good luck
