To clean the parts of a garden sprayer, use plenty of clean water for rinsing the tank and the nozzle several times. Remove any small particles clogging the nozzle. Lubricate the gaskets, and use an anti-corrosive agent on the moving parts of the sprayer.
Before cleaning the parts of a garden sprayer, ensure that the tank is empty. Use all the pesticide in the sprayer, instead of discarding it.
To clean the tank, slowly open the garden sprayer to reduce the pressure within. Now, pour clean and fresh water in the sprayer's tank, and replace its lid. Swirl the water in the tank, increase the pressure within using the pump assembly, and spray the water out. This forces water out of the sprayer's nozzle and cleans it in the process.
For cleaning the nozzle, detach the head fitting of the nozzle by unscrewing it. Then, spray water via the nozzle without its fitting. If the head fitting is clogged, use a blade of grass or a twig to remove the particles. Avoid using a wire for this purpose as it may damage the nozzle and alter its spray pattern.
Repeat the water rinsing process in the tank and nozzle three times. Reduce the pressure of the sprayer, undo the lid, and empty the tank on soil. Run plenty of water on the soil to avoid polluting it with chemicals.
To lubricate the gaskets, use petroleum jelly or a lubricant specified in the owner's manual. Apply the anti-corrosive agent on the pump assembly and the sprayer's handle. After cleaning, keep the tank in an upside-down position, without the lid.
