I'm updating the family's bobs and GHBs and am including cleaning kits for the various weapons we will have. Barrel swabbing and cleaning will be via bore snakes, patches will be included in the kit but I'm having an issue with the cleaning and oiling solutions. My thought is to include glass vials of both and eye droppers for application and volume control so none is wasted. The problem is that any solvent would eat away either the rubber of the dropper or the plastic of the pipette...I think. The storage container I'll be using is 2x3x8 and is sealed so no scent can be detected through it by either man or beast(well, maybe beast) and it'll have one set of cleaning implements for each calibre we've got. The only snag is that storage of the liquids.
