I normally use 91% isopropyl alcohol (isopropanol) as a cleaner and degreaser for metal surfaces and knife internals. From routine maintenance to cleaning the factory gunk out of a new budget folder, it's been a marvelously cheap, effective, and "less toxic" solution. Aside from metal, it works well on G10 and FRN. G10 can look a little dried out after being cleaned with 91% isopropanol but that is easily remedied by buffing with mineral oil. I've hesitated to use it on wood or Micarta. Does anyone have experience using alcohol to clean Micarta? Sadly, the pandemic has made this product much harder to find. Out of frustration, I bought a gallon of 99.9% isopropanol. Does anyone have experience using "pure" isopropyl alcohol for this hobby? I wouldn't imagine a big difference from losing that 9% water but as a wise man once told me: if you don't know, ask.
