My husband noticed that our shower heads were clogged with calcium and mineral deposits. We have hard water, and it tends to collect on the openings of the facets It makes them look ugly and it tends to be hard to remove.
So genious that he is, he soaked them in vinegar overnight and...Voila! Unclogged shower heads. Pretty cool!
It was easy and took no effort to clean (the hardest part was removing the faucets, but that was easy too, they just twist off!)
