But, before you start cleaning off the latex paint, you must assemble the cleaning items. It includes:

  2. A soft-bristled brush 
  3. A garden hose for supplying water 
  4. Two large buckets or container 
  5. A set of pliers 

Step 1: Removing the nozzle of the paint sprayer 

Firstly, start with the tip of the sprayer nozzle. It slides right through a tiny hole. Thus, it easily gets clogged with dry latex paint. You can scrape away the paint from the tip with a soft-bristled brush. Make sure it reaches the tip properly and apply firm pressure to remove the dry paint. 

After that, follow the user instructions of the sprayer to dismantle the nozzle carefully. Make sure you don’t break the nozzle tip in the process. Then, spray water on the nozzle tip and remove any remaining paint from it. 

Step 2: Work with the filters inside

HVLP or airless paint sprayers come with filters to safeguard them from debris and dust. It sits inside the handle of the sprayer. Firstly, remove the screws from the handle and access the filter. You can use the pliers to remove the filter from the handle inside. 

Also, the paint has to pass through the filter before you may spray it. Thus, the filter is thickly covered with latex paint, making the cleaning process pretty difficult. Also, it gets clogged sooner than any other part of your paint sprayer, making it difficult to pass the latex paint material. 

Run the garden hose and spray water with the optimal flow right on the paint to soften it. Then apply paint cleaner on it and use the soft-bristled brush to wipe off the remaining paint from the filter. Make sure you have reached every part of the filter and cleaned it thoroughly.

You may need to run water thoroughly on the sprayer body several times to eliminate its paint. Also, use the brush to rinse off the sprayer body properly. Some may even use soapy water for a better cleaning session. 

Step 4: Clean the inlet strainer using the paint cleaner

You may need to wait for a few minutes to allow the paint cleaner to work properly. After that, run the garden hose once again and rinse off the sprayer. After that, reach out the inlet filter right at the siphon tube’s base. Apply the paint cleaner and scrape it off with the brush. Then, run water on it and clean the remaining paint. 

Step 5: Reassemble the paint sprayer 

Once you have cleaned all the parts of the paint sprayer, allow these parts to dry in the open air. When all the parts are dried, reassemble the filters, handle, and inlet strainer. Now, you can store the sprayer for future use.
