Lysol Power toilet bowl cleaner gel, Cleaning, Disinfecting and Stain Removal, 24 oz, Pack of 2

Works great for toilets. But I accidentally found out it works great for iron stains. We recently purchased an older home and there was carpets in the bathroom! Crazy right!! So the second day there I ripped up the carpets and found the original tile to the home. 1965 tile like new… incredible. But the grout lines was black, brown, yellow just nasty. I used straight bleach and it didn't touch the stains. I used iron remover and still nothing. I said why not let's use this… and oh my goodness my floors are beautiful! This will forever be my go to for grout lines.
