Just stay away from Drano or any cleaner containing a high percentage of sulphuric acid. If you get any of that on your wood grips it'll totally ruin your day. JUST KIDDING! Seriously, Mobil 1 is good, never tried the frog lube and all of the Hoppes products are good. In my mind, as long as you strip them and clean them, no matter what you use, your guns will stay like new forever.
