What do they mean?

I'm reading a book called the complete illustrated guide to coin collecting. They say " generally speaking, a good decreasing solvent will work wonders in removing surface grime. A drop or two of good quality lighter fuel on the surface of the coin, gently wipe off with a very soft cloth, will remove all of or most of the dirt." Beforehand they are talking about human hands oil. My question is, what is lighter fuel? I found 3 different types listed in wikki.

    "My question is, what is lighter fuel?"

    It is the fuel/fluid that is commonly used in Zippo lighters.

    I would not recommend it for cleaning coins. Hot water, acetone or Isopropyl alcohol would be better.

    Edited to add: Don't wipe your coins while cleaning.

    Wow - that is new enough that I would not expect to see that sort of advice. But what do I know. :D

    In general, the age of a book can be very significant since acceptable methods, trends, and even known varieties can change or be missing. The topic reminds me of a book I have: "The Modern Practice of Photography"....printed in the 1850s. :o

    Acetone good. Wiping bad! Gentle pat of coin surface with acetone soaked qtip is doable. Peace Roy
