I'm a pro cleaner & here are three things you probably didn't know!1- bar soap causes more soap scum buildup than liquid soap 2- if mildew is so severe that it is embedded in the caulk or grout, you will need to regrout or recaulk to completely remove the mildew 3- 70% isopropyl alcohol is a great disinfectant but don't dilute it. Don't use 91%, 70% is more effective. Let it sit a minimum of 30 seconds before wiping away #cleaningtipsandhacks #mildewremoval #CleaningMadeEasy | Zapata’s Cleaning
