How to Properly Clean Your Gun With a Spray Gun Cleaner
When using spray guns, it is important to remember to follow the manufacturer's instructions. While it is not always necessary to do so, some precautions are usually taken for safety reasons. There are some gun cleaners that contain solvents that can be hazardous to both the gun and the user. The main things to consider when using a spray gun cleaner are:
To clean the nozzle, a special spray gun cleaner kit and some chemicals may need to be used. Clean capacity: It should be strong enough to force out the smallest particles. Nylon fiber: A nozzle should be able to fit into a nylon fiber filter well. This makes the nozzle less likely to clog. Rag: A rag should be used to wipe away any excess solvent residue, which will prevent the gun from working as well as possible.
When cleaning the gun's paint cup, care should be taken so as not to damage the plastic lining. In some models, a gun can be purchased that comes with a primer pocket. In other models, the paint cup must be removed before the cleaning takes place. For the first test, put a drop or two of the solvent in the gun's paint cup and then insert the needle into the gun's primer pocket. If the cleaner leaks out, this means the gun needs to be repaired.
After the gun has been disassembled, a solution of one part water to three parts oil should be added to the compressed air. The gun should be allowed to dry thoroughly between cycles. Once the solvent has been removed by shaking, the compressed air should be pumped in the gun's crankcase. The solvent will settle in the buttstock and then be vacuumed out.
Next, the solvent will need to be squeezed out of the compressed air cap. The gun should be loaded again and then shot with a stream of compressed air. As the compressed air hits the air cap, the solvent will be blown out through the nozzle. The cleaner will settle in the tube on the bottom of the gun and will need to be squeezed again. Once the solvent is removed completely, the gun should be reloaded. It may take several times of these repetitions for the solvent to be completely removed.
With every cleaning cycle, the gun should be shot with a fresh stream of compressed air. This will help ensure that no remaining solvent will be drawn back into the air cylinder. This ensures that the gun will always be completely clean when it is returned to its user. If the reservoir is dirty, however, even these simple cleaning procedures won't prevent the gun from shooting uncontrollably.
Spray gun cleaning requires a specific regimen that will take away all of the gun's finishing materials. These materials include the finish and any special paints that were used during manufacturing. Also, the oils and other chemicals that were used to lubricate the moving parts will need to be taken away. These items should always be wiped away before cleaning the moving parts of the gun. It will also help to give the cleaner time to work. Without doing this, the cleaner can possibly remove too much cleaning product and air.
After the gun is thoroughly cleaned, it will then be necessary to give it a thorough rinse in order to remove all of the remaining solvent and air from the moving parts. The nozzle should be carefully washed with a detergent specifically designed for gun cleaning. It will help to use a nozzle brush while working in order to scrub off any hardeners and other materials. If there is any hardener in the nozzle, a good quality wire brush can be used to properly remove it.
