How to Clean an Airless Paint Sprayer

Maintaining your airless paint sprayer is crucial to ensure its longevity and optimal performance. Cleaning the sprayer after each use not only keeps it in top shape but also improves the quality of your paint jobs. In this article, we will guide you through the process of effectively cleaning an airless paint sprayer, providing you with the knowledge needed to achieve professional results.

Before delving into the step-by-step cleaning process, it’s important to understand the components of an airless paint sprayer. Generally consisting of a pump, hose, gun, and tip, each part plays a vital role in paint application. Cleaning these components thoroughly is essential for maintaining their functionality and preventing clogs or other issues.

Step 1: Gather the necessary supplies

To begin the cleaning process, you’ll need the following supplies:

– Safety goggles and gloves

– A bucket or container for cleaning solution

– A wire brush or toothbrush for scrubbing

– A wrench or pliers for removing the tip

– A cleaning solution, such as water, mineral spirits, or a specialized paint thinner

– A clean cloth or rag for wiping

Step 2: Prepare the cleaning solution

Depending on the type of paint you used, you’ll need to choose an appropriate cleaning solution. Water works well for latex-based paints, while mineral spirits or paint thinner are more suitable for oil-based paints. Alternatively, there are also cleaning solutions available specifically designed for airless paint sprayers. Follow the manufacturer’s instructions when using these products.

Step 3: Flush out the sprayer

Begin by removing the paint from the sprayer. If there is any leftover paint in the container, transfer it to a separate storage container for future use. Then, remove the spray tip and guard from the gun using a wrench or pliers. Take care not to damage the tip threads. Place these parts in the cleaning solution for a thorough soak.

With the tip and guard removed, set the sprayer’s prime valve to “siphon” or “bypass” mode. This setting allows the cleaning solution to flow through the pump, hose, and gun without pressurizing the system. Aim the gun into the bucket or container and trigger the sprayer to flush out any remaining paint within the airless system. Repeat this step until the expelled liquid is clear.

Step 4: Clean the components

Now that the bulk of the paint is out of the system, it’s time to clean each individual component. Start with the spray tip and guard that have been soaking in the cleaning solution. Gently scrub them with a brush to remove any residual paint or debris. Rinse them thoroughly with water and set them aside to dry.

Next, clean the gun by disassembling its parts carefully. Depending on the design, you may need to remove the nozzle, trigger, and filters. Use the wire brush or toothbrush to scrub away any paint residue. Rinse each piece thoroughly with water and dry with a clean cloth before reassembling the gun.

Step 5: Reassemble and store

Once all the components are clean and dry, reassemble the airless paint sprayer. Ensure that all parts fit together securely and that there are no loose or damaged items. Properly store the sprayer in a clean and dry environment, ready for the next painting project.

Remember, the cleaning process should be repeated after every use. Neglecting to clean your airless paint sprayer regularly can result in clogs, decreased performance, and even permanent damage to the equipment. By following these cleaning instructions, you can extend the lifespan of your sprayer and maintain its high-quality performance.
