There are two types of can foam; "Gun Foam, and Straw Foam (used w/ a plastic straw)".

 They produce similar foam results. Gun foams offer greater control and savings, as you can use some now and later. 

Our guns, like all foam guns, work with all “gun foams”. And who’s ever "gun foam" you choose to use; they will also sell a Gun cleaner.

 This cleaner will have the same style attachment as the foam.

Your gun will not need to be cleaned after each use. 

You should never store your gun with an empty can, OR without a can attached, and always store with full or partial can upside down(Gun upright).

 Use the cleaner to "flush" the gun every 6 to 8 cans when using consistently. 

If you store the gun, as said above, for a length of time (a month or longer), 

finish the attached can of foam upon the next use, remove and attach the cleaner. 

Use only 10 to 15% of the cleaner to flush the gun, attach a new can of foam and your ready to go.

While hardened foam on the outside is more difficult to remove, you will be able to get it off using the cleaner in small amounts.

 IMPORTANT; be very careful not to scratch or damage the "Ball stopper" in the gun where the can attaches!
