First of all, do not ever thin the K-Spray glue or the DAP Weldwood Top and Trim Contact adhesive. They work fine right out of their containers and do not need to be thinned. Neither one will hold properly if thinned to spray properly. If the Critter doesn't spray, it is not adjusted correctly, it is not the glue. The Critter sprayer will not spray the DAP contact adhesive, don't even try it. Leave the glue in the mason jar on the Critter, don't ever pour either glue back into the cans they came in. If you want to, you can take the mason jar off the Critter sprayer and cover it with a lid and screw top, but it is definitely not necessary. The only time I do that is if I change from one color glue to another.
Second of all, I have had Critter sprayers for a long time, and have never ever taken one apart and cleaned one. The only thing I do is not leave the sprayer hooked up to the air hose. Once it is adjusted to spray the K-Spray correctly, the Critter can sit for weeks without being used and still spray just fine. The only thing that ever needs to be cleaned is the opening to the vertical nozzle right below the horizontal nozzle, and that is only if a film of glue covers over that opening, which happens once in a while. That will stop the Critter from spraying until you use some mineral spirits to clear the opening off. The only thing that is a solvent for the K-Spray or the DAP is mineral spirits or Xylol, which is just a better (more expensive) grade of mineral spirits. Do not try anything else, it simply won't work.
No one lives forever, the trick is creating something that will.
