 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.

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.

 ==Looking at the Fiber==
-What you see depends on how you hold the fiber. The fibers have a square cross-section. If your line of sight is perpendicular to a face of the fiber, you may see only the paint. But holding the fiber up to the light or rotating it can make the underlying color visible. If you rotate the fiber, you can see the color on the shaded underside. Gaining familiarity with the appearance of the fiber as it is rotated may help the worker to recognize a good paint coat.
+What you see depends on how you hold the fiber. The fibers have (approximately) a square cross-section. (What look like the sides of the square are in fact curved.) If your line of sight is perpendicular to a face of the fiber, you may see only the paint. But holding the fiber up to the light or rotating it can make the underlying color visible. If you rotate the fiber, you can see the color on the shaded underside. Gaining familiarity with the appearance of the fiber as it is rotated may help the worker to recognize a good paint coat.
 ==Measuring the Paint Coat==
 Using a micrometer to measure the paint thickness can damage the paint on a fiber. The sharp edges of the spindle and the anvil can easily scrape off paint as the the fiber is placed between them and as the screw is tightened. Putting masking tape over these sharp edges may reduce damage to the paint. To avoid scraping the paint after recording a measurement, let the fiber fall rather than holding on to it as you are loosening the screw.
