Dawn + Vinegar = Soap Scum KILLA! So it's pretty simple. Heat up some vinegar. Then pour it in your spray bottle, add an equal amount of blue Dawn (the website comments were pretty specific about getting the blue kind), shake gently, and voila! Spray on, let sit for 30 mins -2 hours and wipe clean with a damp sponge.
OK, this works! My shower has never been this squeaky clean. 1 cup White vinegar heated up (microwave 1-2 min) with equal amount blue Dawn, gently shake and spray on and wait and then wipe away the soap scum. Thank you Pinterest!
"Life Crafts & Whatever: Dawn + Vinegar = Soap Scum KILLA" Used this to clean the bathroom sinks and tub- works way better on hard water and soap scum film than scrubbing bubbles ever did for me! Also used it to clean outdoor kid toys (see other pin). I'm sold! Equal parts hot vinegar and dish soap
