Remove hard water deposits from lawn sprinklers

Who says the lawn is greener on the other side of the fence? Not Carol, from Riverside County, California. Our second winner of the CLR 101 Uses Contest writes, 

I use it CLR to refresh my outdoor sprinklers in the spring. It clears the hard water deposits and helps them work well.

Over time, water flow from sprinklers can be hampered due to a build-up of calcium or rust. As a result, water is unable to spread evenly on the lawn causing green patches and brown grass, while flooding other areas. A build-up of rust on the sprinkler heads may even leave rust stains on sidewalks, driveways, cars and other items. To combat this, it’s important to maintain a clean sprinkler.

Things you will need:

  • CLR® Calcium, Lime, Rust Remover
  • Brush, cloth or sponge
  • Rubber or latex gloves
  • Warm water and a bucket

Let’s get started:

  1. In a well-ventilated area, mix equal amounts of CLR and warm water. Never mix CLR with other household cleaners or bleach. 
  2. Inspect your sprinkler heads to assess the amount of calcium build-up and grime that might be affecting your water flow. 
  3. If the build-up is minimal, simply wipe the sprinkler head with a brush, cloth, or sponge. After 2-3 minutes, rinse with cold water. 
  4. If you see extensive build up, you may need to remove and submerge the sprinkler heads in the CLR/warm water solution. Immediately rinse with cold water and replace the head.
  5. Enjoy your beautiful lawn!
