Well, technically, no. However, if you want to improve your water flow it is a very good idea. It’s also very cheap to clean and very earth friendly and also, easy. You will need:
Add vinegar to a ziplock bag and use the rubber band to secure it around the shower head. Wait an hour and voila…clean and unclogged shower head. Cleaned using a green method too!
I know, right, who sits around and thinks up this stuff?
