clean your pinch roller... with gasoline!

The other day I got an old Craig portable reel-to-reel machine at a thrift store; quite a find, still has all the accesories; and as I was browsing through the 1961 instruction manual... It said that an alternative chemical to clean your rubber pinch roller with is, yes-, gasoline.

I have brought up this thread purely for amusement. I wouldn't clean any rubber parts with gasoline nowadays; as it contains ethenol, rubber's nemesis.
