Milfoam foam is a high-tech method of barrel cleaning. It works as easy as through an insertion of a foam into a barrel duct. After the insertion it is neccesary to make sure that the thick, white foam fullfills the entire barrel. After the fullfilment wait 20-30 minutes, afterwards remove it with a use of a blade. Foam, during the chemical reaction with copper, turn a color blue; and after a contact with a powder and coal/carbon it becomes of a black color. Now, when the barrel is perfectly clean (in a situation of a major dirt repeat a cleaning procedure) it holds out to maintain it with a Milfoam oil.
