Clean Clogged Sprinklers

If you have a lot of iron or other minerals in your water, then you likely know how much of a problem they can create. Iron builds up on the working parts and in the holes of sprinklers, which over time can make them quit working altogether. Here’s the good news: a simple soaking in a rust-removing solution followed by a spritz of silicone lubricant is all it takes to rejuvenate your sprinkler.

Step 1

Soak Sprinklers in Rust Remover

Fill a freezer bag half full of rust remover and drop your sprinkler into the bag. We used CLR Calcium, Lime, and Rust Remover, but other rust-removing solutions will also work. Swish it around occasionally to distribute the solution. Remove the sprinkler after 30 minutes and rinse it in clear water.

Step 2

Spray With Silicone

Clean off any remaining mineral or rust buildup with a brass-bristle brush. Spray silicone on the cleaned-up sprinkler to lubricate the parts and to prevent iron and mineral buildup.
