Out standard procedure with Wipe-Out is to insert an O-ring-sealed cleaning rod guide into the chamber and then squirt through the muzzle in short puffs. Put a towel or rag on the comb of your stock and watch for a little bit of foam to exit the rod guide. We usually wait 30 minutes for the bubbles to dissipate, then do a second foam application. Be sure to clean off any excess foam before it drips on your stock.

Applying Wipe-Out from Breech
You can also apply Wipe-Out from the breech. To allow breech-first application, Wipe-Out cans now come with a short plastic tube and a plastic tip that fits in your chamber. These can also be purchased separately for $2.50. However, we’ve found the plastic tip is too big for some chambers and it is not always easy to get a good, secure seal even if it does fit. Jason Baney has come up with a solution. READ Jason’s Wipe-Out Article.

Use Fitted Tubing for Breech-First Applications of Wipe-Out
You can apply Wipe-Out through the breech very effectively if you use fitted, plastic tubing. While this works well for bolt-actions, breech application is particularly handy for the Garand, M1A and other semi-autos. Jason Baney has written a short article describing this process. In a nutshell, you need one piece of tubing that fits the chamber tightly and then connects with a second, smaller diameter tube that attaches to the Wipe-Out can. This avoids any “over-spray” of foam in the action area, providing a clean, simple solution. Just squirt for a second or so, and wait for white foam to come out of the muzzle. Be sure to keep Wipe-Out off fine wood stocks.
