How to Use Them:

First, disconnect the powder hose from the hopper/pump and gun.

Next, insert one hose cleaner into one end of the hose.

Next, use an air blow gun to force compressed air into the hose, shooting the cleaners out the other end.

Repeat this process 2-3 times until plug returns clean.
