Q: We replaced our shower head about a year ago and it’s already starting to show lime scale buildup. How do we prevent this?
A: This is fairly common here in NE Florida given the aquifer below is porous limestone. Actual prevention of this challenge requires changing the water chemistry, which you can do with a water softener. There are both installation and ongoing costs associated with this approach, but many take this path.
Periodically removing the scale is another option. A mild acid will do the trick, including vinegar, lemon juice or a commercial lime scale remover. The trick is keeping the acid in contact with the item being cleaned, as this is not a wipe-on/wipe-off solution. Immersion and time will be required, with heavier buildup taking longer to dissolve. Removing the shower head periodically and submerging it is the easiest way to do this.
