Three parts of rubbing alcohol, three parts hydrogen peroxide and two parts Murphy's oil soap. Not my recipe, can't remember where I got it or I would give the credit due.
The correct recipe is, 2 parts isoproply alcohol (rubbing alcohol 70%. Walmart has it).....2 parts hydrogen peroxide......1 part Murphy's Oil Soap. Stirred not shaken :wink: . Store in a dark container.
I have used this for YEARS and it is in MHO, the best thing going. Here is HOW i use it....
Dry brush bore with a nylon brush, dump out soot.
Block off nipple and pour barrel full, leave a half inch low at muzzle.
Stand rifle in corner for 30 minutes...it will foam up a little.
Pour out cleaner then brush vigorously while barrel is still wet.
Push wet patches through until no discoloration shows.
Wet/dry patches with CARBURATOR CLEANER to finish clean.
Oil bore with 3 in 1 oil.
I have polished bores that stay mirror finished with this system and on any given day my rifles will shoot clover leaf groups to 100 yards. Hope this helps....
P.S. the wife don't like the smell of carb cleaner but I do....I have a shop to clean my rifles in.
