How to Clean a Garden Sprayer

Use every bit of the pesticide in the sprayer. Never leave unused chemicals in the sprayer for more than a few hours.

Clean the empty tank over a dirt area, never over concrete or in a sink. Unused chemicals may flow into waterways, causing harm to fish and wildlife. Make sure you have plenty of fresh water on hand.

Open the sprayer slowly to release the pressure.

Fill the tank with fresh, clean water, close the lid, then swish the water around inside the tank.

Pump up the pressure and spray the fresh water through the nozzle.

Unscrew the nozzle fitting to check for clogs. Spray clear water though the nozzle with the head fitting removed.

Dislodge small particles from the nozzle with a small twig or blade of grass. Never use wire to clean the nozzle since it may scratch the metal and cause a change in the flow pattern.

Release the pressure, open the lid and pour the water onto the bare soil. If you are working with a garden hose as your source of water, let it run to dilute the chemical on the soil.

Rinse the tank three separate times, spraying clean water through the nozzle each time.

Store the tank upside down with the lid open.
