Things You'll Need
Canned air duster
If your plumbing suffers from hard water, the result of excess mineral deposits in your water supply, you have likely noticed the unpleasant results in a number of ways, from the taste of your tap water to the hard-water spots on your newly-washed car. A water softener solves this problem by filtering the minerals out of your water supply, but to keep your water softener working properly, you must keep your injectors clean.
Switch the control valve on the water softener control to "Bypass" mode. You should find the valve between the hard-water and soft-water pipes connected to the water softener.

Unplug your water softener unit from its electrical source if it is connected to live electricity.
Unscrew your injector cap beneath your control valve, using a screwdriver. If you do not know the exact location of your injector cap, refer to your owner's manual, as the location will vary depending on your model.
Remove the injector screen beneath the control valve on the water softener component. Scrub it with soap and warm water. Rinse thoroughly when finished. Replace the screen immediately if you see any signs of damage.
Remove the injector nozzle from your component. Look for it beneath your control valve, opposite the injector screen.
Clean your injector nozzle, using a canned air duster or paper clip to remove the buildup.
Reassemble your water softener, using a screwdriver.
