Stain remover yellowed shirt arm pits, grease, wine, etc. 1 part Dawn dishwashing liquid and 2 parts hydrogen peroxide. May add a bit of baking soda for scrubbing. Let it sit.
This ain't called "Miracle Soap Scum Remover" for nothin'. I have never found anything to clean soap scum as well as this does! Fair warning: Your bathroom will reek of vinegar for hours, especially if you let it sit overnight (which is really the key), and your arm will be sore from all the scrubbing. But... it's totally worth it in the end when it looks like you have a BRAND NEW shower.
Need to try this...miracle soap scum remover
