For a bunch of home brews go to:
and look under "Homemade Cleaners and Lubricants"
I heard this gentleman writes companies and requests some government mandate form that lists all the contents of their products. I think it's some EPA required thing. From that he can replicate the brew. Rumor has it some very popular cleaning goops and lubing goos are VERY common stuff, BIG PROFITS! No wonder there's a new one every month...
