How to clean your shower head: A simple 1-hour science hack for degunking

Mineral buildup is usually the culprit behind clogged spouts and uneven water flow. Here's how to knock it out fast without breaking a sweat.

If you've realized that the water flow from your once-torrential shower head has become a mere trickle, mineral buildup from hard water is probably to blame. Luckily, you can fix this problem with minimal effort -- all you need is just over an hour and a few common household supplies. 

First gather a zip-close food storage bag (like one from Ziploc or Hefty brands) and a sturdy rubber band. Next, locate either some calcium, lime and rust-removing cleaning solution (like CLR brand) -- or, in a pinch, a bottle of white vinegar -- then set aside about 60 minutes to let science do the work for you.

The problem with your jets stems from hard water, which has high levels of dissolved solids -- primarily calcium and magnesium -- according to the Water Quality Association. Over time, these chemicals bond with the metal and plastic in your shower head, causing a buildup that appears as crusty bits around the water spouts.

As this plumbing plaque accrues over time, the holes start to close up and water has to work harder to shoot out. If ignored, eventually it can stop up your spout completely. Shower filters are one way of preventing the problem, but to open up an existing clog, don't worry about calling a plumber, buying expensive replacement hardware or setting aside a whole afternoon to fix it. 

Here's how to degunk your shower head.

1. Gather your cleaning gear

First, gather your supplies. If you've got a small shower head, a sandwich-sized bag should do, but for larger hardware you might have to whip out a gallon bag. You'll need a rubber band to tie it up, and water can get heavy, so be sure to use a strong one. The kind used to hold together produce like asparagus or broccoli is perfect, but your run-of-the-mill rubber band from an office supply store will do, although you might need more than one, especially for a gallon bag. 

For the cleaning solution, you'll need a 50/50 solution of either CLR household cleaner (available at most grocery stores, Walmart and Amazon) or white vinegar (the stuff in your cupboard will do) and plain ol' shower water.

2. Soak away the grime

Fill the bag halfway with either CLR or white vinegar then insert the shower head into the bag as well. Secure it with the rubber band(s), then gently turn on the water to the shower just enough to fill the bag the rest of the way and mix up the solution. Whatever you do, don't crank the shower on full-blast, or else the sudden pressure may inadvertently launch your plastic bag across your bathroom. 

Next, set a timer for 60 minutes, either on your phone or using your smart home assistant. Here's how to set multiple timers with Google Home, as well as with Amazon's Alexa on Echo devices. Now, go relax with a podcast for the next hour.

3. Wipe, rinse and (hopefully) no need to repeat

After your timer goes off, remove the bag from your shower head and let the cleaning solution spill into the drain. Toss the bag in the trash and wipe down your shower hardware with a damp cloth. 

Then, the moment of truth: turn on your shower (full-blast, this time) and see how much more powerful and evenly it sprays. If, for some reason, there are still a few clogged spouts, feel free to repeat this process. But for most clogged shower heads, one round should do the trick.
