If the paintbrush is not working when you are trying to paint, you may want to clean it partially by spraying water. If you do not want to do a thorough cleaning, do not separate the tube from the paintbrush. Inserting the tube back into the inlet sleeve without washing the tube and the sleeve will cause the tube to stick to the sleeve when the paint dries. Pulling hard on the lid to detach the tube from the sleeve will then loosen the seal, and the paint will no longer spray. A better plan for incomplete cleaning is to leave the tube in the sleeve, unscrew the lid from the jar, and screw it onto another jar full of water or dip the brush and tube in a bucket and operate the brush underwater.

To avoid damaging the seal mentioned above, it is best not to pull on the jar lid to remove the tube from the inlet sleeve. To this end, there is a wider rounded section of the tube that you can grip if you cannot hold on closer to the tube exit.

===Cleaning the Paintbrush with Isopropyl Alcohol - After Using Water===
We are using acrylic paint, which can dissolve in [http://www.artistdaily.com/forums/t/13771.aspx isopropyl alcohol]. After cleaning the paintbrush with water, it should be further cleaned by diluting the alcohol in water and spraying the solution. This cleaning should be done near the hose that draws air out of the lab to avoid breathing the alcohol vapors too much. After spraying the water and alcohol, remember to spray some water without alcohol to clear the brush of alcohol.
