To clean an airless sprayer after latex paint, flush it with water right after spraying, then clean the gun, tip, and filter. Follow the manual for pressure relief and storage, because the steps and parts can differ by model.

Work promptly while the paint is still wet. Keep the trigger pointed into a suitable waste container during flushing, and wear eye protection and gloves.

What should you do before cleaning an airless sprayer?

Relieve pressure and make the sprayer safe before disconnecting or cleaning any parts. Follow your model's manual for the pressure-relief procedure, trigger lock, and power switch.

Airless equipment can hold pressure after the motor stops. Never point the gun at yourself or anyone else, and don't put a hand near the spray tip.

Gather clean water, a waste container, and soft brushes or cloths approved by the manual. Keep water away from electrical connections, cords, and the motor.

How do you flush latex paint from the pump and hose?

Flush the pump and hose with water until the discharge runs clear. Use the intake and waste setup in the manual, and keep the gun directed into the waste container.

1. Turn the sprayer off and relieve pressure as instructed.
2. Move the intake tube from the paint into clean water.
3. Place the drain or return tube in a waste container.
4. Start the flushing cycle described in the manual.
5. When the return flow is clear, switch to the spray gun if the manual calls for it.
6. Flush through the gun into the waste container until the water is clear.

Don't run the pump dry or let a bucket run empty. If the paint has started to dry, stop and check the manual rather than forcing the system to run.

For a Graco unit, the Magnum X5 includes a PowerFlush adapter. Match any flushing accessory to your model's instructions.

How do you clean the spray gun, tip, and filter?

After flushing, relieve pressure again and clean removable parts as the manual directs. Rinse the gun, tip, guard, and filters with water, and use a soft brush to loosen wet paint.

Don't scrape the tip with a pin, wire, or knife. A damaged opening can affect the spray pattern.

Check the filter and other removable parts for dried paint or clogs. Reassemble them in the correct order, using the manual's diagrams if needed.

If the sprayer starts spitting on the next job, a blocked tip or dirty filter may be one cause. Our guide to why a paint sprayer is spitting covers other causes and checks.

Which cleaners and brushes should you use?

Use water for latex paint unless your paint or sprayer instructions specify another cleaner. A soft brush can help with wet residue on removable parts, but the manual sets the limits for your model.

The Wagner Control Pro 130 is described as gravity-fed for priming and cleaning, with a flush-and-rinse cleanup process. Follow Wagner's Control Pro 130 instructions for the correct steps.

Don't use a strong solvent or abrasive tool just because paint remains. Check the paint label and sprayer manual before changing cleaners.

How do you clean an airless sprayer tip safely?

Rinse the tip and guard after relieving pressure, and use only a soft brush for remaining wet paint. Keep the tip turned away from people, and follow the manual's removal and reinstallation steps.

If paint has dried inside the opening, don't force a sharp object through it. Use the cleaning method approved for your tip, or contact the manufacturer for guidance.

Check the tip and guard for damage before reinstalling them. Keep the guard in place whenever you spray.

How should you store the sprayer after cleanup?

Complete the storage steps in your sprayer manual before putting the equipment away. Some models call for a storage fluid or another procedure after flushing, so clear water alone may not be the full process.

The Magnum X5 includes Pump Armor storage fluid. Use it only as directed for that sprayer, and don't assume it is right for another model.

The Graco TrueCoat One is designed for projects up to 3 gallons and includes a 25 ft hose and PowerFlush adapter. Check its manual for how to flush and store that model.

Store the sprayer and cleaned parts in a dry place, with the hose and gun arranged as the manual recommends. For coating preparation next time, see water-to-paint ratio for a paint sprayer.

What mistakes make airless sprayer cleanup harder?

Waiting until paint dries is the main cleanup mistake. Flush the system promptly, and don't leave paint in the pump, hose, gun, or tip while you clean other tools.

Other mistakes can damage the sprayer or create a hazard:

• Skipping the pressure-relief steps.
• Running the pump without enough water.
• Using a metal pick on the tip.
• Immersing the motor or electrical parts.
• Storing the sprayer without its required storage procedure.

What is the right cleanup routine after latex paint?

For anyone learning how to clean an airless sprayer, flush promptly, clean removable parts, then follow the model's storage steps. The manual is the guide for pressure relief, part removal, cleaning fluid, and storage.

The Magnum X5 includes a PowerFlush adapter and Pump Armor storage fluid. The Control Pro 130 uses a gravity-fed setup and a flush-and-rinse cleanup process, while the TrueCoat One includes a PowerFlush adapter.

Choose the cleaning steps for your specific sprayer, and start before latex paint dries. When you're ready for another job, use our airless sprayer picks to compare equipment options.

Frequently asked questions

Can I leave latex paint in an airless sprayer overnight?

Don't leave latex paint sitting in the sprayer overnight. Flush it promptly, since paint left in the pump, hose, gun, or tip can dry and make cleanup harder.

If you must pause, follow the manual for your model and keep the system in the specified safe state.

Do you clean an airless sprayer with water?

Water is commonly used to flush water-based latex paint, but follow your sprayer and paint instructions for the right cleaning fluid. Flush until the discharge runs clear, then clean removable parts as directed.

Don't immerse electrical parts or use solvents unless the manual allows them.

How do I clean an airless sprayer tip?

Relieve pressure first, remove the tip and guard as directed, and rinse them with water. Use a soft brush if paint remains, and avoid metal objects that can damage the opening.

Reinstall the parts only after checking the manual's orientation and assembly instructions.

How often should I clean an airless paint sprayer?

Clean an airless paint sprayer after each session, including short jobs, before paint can dry inside the system. If you change colors or coatings, flush as the manual directs before loading the next material.

Complete the model's storage steps if you won't use it soon.
