Yeah adults don't seem to share the same sense of humor as young'uns do sometimes. I get bigger and better understand that myself.

Coleman Fuel is a great gun cleaner, cleaner period. More than one person still cleans steel guns with this Coleman Fuel.
They take an empty Coleman Fuel can , or Antifreeze gallon container and cut out the side, put parts, guns whatever and clean, then just unscrew the cap, and pour back thru a cloth or whatever filter and back into a Coleman Fuel can marked to indicate "Cleaning Mixture" or somesuch.
To keep from getting cut by metal or plastic edges - take a pc of Aquarium tubing, windshield washer tubing or similar, slit it, and apply to where cut out.
