I use the spray as a handyman to clean my foam gun. You can screw the socket directly to the gun and this easy clean it. To clean the gun from the outside or the connection thread for foam cans Cleaner Spray is a spray head. This is attached with a thin plastic strand to the can. Unfortunately, this is broken very quickly. Now you just have to spray head with adhesive tape on the can so that it stick is not lost. The cleaning spray is this is not a disadvantage. Foam residues but you should still remove them from drying out.
