I just made my first batch of Dutch's recipe of Moose Milk. I.e. 22 parts water (I used distilled), 1 part Ballistol and one part Pinesol. My question is, how long will it keep in storage? I made about a half gallon or a little more. I intend to use it as a between shot cleaner sparingly on the wiping patches. May also use it to clean my rifles after shooting. Theoretically, there is nothing in it that should go bad. Just wondered what is the consensus of others who have much more experience than I do with this stuff. Thanks.
