We've been dealing with something here in Boise that I've never had to deal with before...
...Da da duuuumm...
For the life of me I could not figure out why the shower heads in our rental house not only sprayed in seven different directions, but also seemed hell bent on spraying me as hard as they possibly could.
Then I took a closer look and realized that nasty white gunk had built up on the spray nozzle of our shower head, completely covering some of the tiny openings for water (anyone know what those are called?) and making the ones that were still open spray crazily in all directions.
I decided that now would be a good time to try some DIY shower cleaner! In a gallon freezer Ziploc bag I put 2 cups of warm vinegar, and 1/3 cup of baking soda. Then I wrapped it around our shower head and used a hair tie to keep it in place:
Then I left it on for a good eight hours to soak. When I took it off the next morning I scrubbed at it with a sponge to remove any residual crusties, and it works great!
Now, it's an old shower head. So it's not as clean as, say, a brand new one. But what it doesn't do anymore is feel like I'm being sprayed with tiny needles of water from all sides! Instead we have a gentle downpour of water. Hooray! I can highly recommend this DIY to anyone who needs a cleaner, gentler shower.
