To clean stubborn stains from your toilet bowl, first if you have a wet/dry vacuum, suck out all the water so you have a virtually liquid free bowl. Then, pour in hydrogen peroxide. It will get rid of all stains and lime.I would suggest using 1/2 a bottle for each cleaning.You might need more or less.ou can also try lemon juice which is citric acid. For stains at the bottom of the bowl, empty all the water out of the toilet and pour in straight vinegar high enough to cover the stain. Then just let it sit until gone.
