I may try Lucas. a friend of mine is sponsered by them. however, my real problem is with the solvent cleaners, not so much the lube. Break free does not bother me much, but I cant stand Kroil or Hoppes #9 anymore. so I might stick with the Frog lube cleaners until I run out, anyway. Any comments on using a non-petrol natural cleaner with a petrol based lube?
