Disconnect and Prepare the Sprayer

First, ensure that the paint sprayer is disconnected from the power source. If the sprayer contains any remaining paint, carefully pour it back into the paint container. Remove any detachable parts, such as the spray tip, nozzle, and paint container, according to the manufacturer’s instructions.

Flush the System

Fill a container with an appropriate solvent or paint thinner recommended by the paint sprayer manufacturer. Attach the container to the sprayer, following the instructions provided. Turn on the sprayer and allow the solvent to flow through the system, flushing out any remaining paint.

Disassemble and Clean Detachable Parts

While the solvent is flowing through the system, disassemble the detachable parts. Use a cleaning brush dipped in solvent to scrub the spray tip, nozzle, and paint container thoroughly. Pay special attention to any clogged or hardened paint deposits, ensuring they are completely removed. Rinse the parts with clean water to remove any residual solvent or paint.

Clean the Spray Gun

Once the system is flushed and the detachable parts are cleaned, focus on cleaning the spray gun itself. Remove the spray gun from the paint sprayer unit, following the manufacturer’s instructions. Using a brush and solvent, clean the interior and exterior of the spray gun, including the trigger mechanism, fluid passages, and air cap.

Rinse and Reassemble

After thorough cleaning, rinse all the parts with clean water to remove any remaining solvent or paint residue. Dry the components using a clean cloth or allow them to air dry completely. Once dry, reassemble the detachable parts, ensuring they are securely attached to the paint sprayer.

Final Checks and Storage

Before storing the paint sprayer, perform a final check to ensure all parts are properly cleaned and reassembled. Inspect the spray gun for any signs of clogs or remaining paint particles. If necessary, repeat the cleaning process for stubborn deposits. Store the paint sprayer in a clean and dry location, away from extreme temperatures and direct sunlight.
