Gro-King Sprayer and Equipment must be cleaned after every use.

Our Neutralizer is a fine, granular, & non-toxic 100% sodium carbonate formulated to quickly dissolve in water for cleaning your sprayer & accessories. 

To maintain performance & protect your warranty, Gro-King Garden Sprayers include 10lbs. of Neutralizer & cleaning instructions with every sprayer order. 

Cleaning is particularly important to the performance of Gro-King Garden Sprayers when applying compost tea/extract or other solutions that may be sticky or oily. Improper cleaning will clog your sprayer pump, hose & other critical components.

Regular cleaning will extend the life of your equipment and provide several benefits:

• Restore internal surfaces to 7.0 pH
• Prevent cross-contamination by removing residue of solutions from all internal working parts 
• Extends life of pump diaphragm & spray guns

Leaving solutions of any kind (nutrients, pesticides or compost teas) in the sprayer between uses may:

• Result in cross-contamination between nutrients & pesticides
• Allow build-up of bio-film
• Weaken the pump diaphragm & clog internal parts of the spray gun
• Cause parts to become brittle & crack
• Void the Warranty
