For a long time I also used a modified ...Eds Red... formula..
1 part K1
1 part Dexron ATF
This for a general cleaner, lube..
I mixed
2 parts K1
1 part Dexron ATF
This for tougher jobs, like when we cleaned Firearms Safety Class 22 rifles once a year..
The old retired Federal Cartridge chemist I met recomended this mix.. NEVER using acetone, lanolin, amonia.. As these corrode worse than powder fowling..
My 5 cents of experience..
