MIRACLE CLEANING PASTE!! This $9 AMAZON CLEANING PASTE TOOK OFF 1 weeks worth of calcium build up. I know it looks disgusting, but our town has very hard water and we don’t have a water softener. This @lovestardrops is the only product I’ve found that has easily taken off the buildup! It can also be used on other surfaces and comes in a spray bottle as well! LTKunder100 LTKunder50 LTKhome
