Pour a half cup of hydrogen peroxide in the toilet and let it sit 20-30 minutes. Use your toilet brush as you normally would.
Pour half a cup of hydrogen peroxide in your toilets to clean and sanitize them. Allow it sit for half an hour. Then, follow up with your toilet brush.
With 3% solution (common), I would pour the entire 12 or 16 Oz bottle in there. It’s $1 at the dollar stores.
I wouldn’t waste food grade hp on my toilet.

It's easy to make and easy to use... I would recommend using microfiber clothes with it, you would be surprised to see the result.
Hope it helps! Bushra
