First, are you talking about cartridges or muzzleloading? If you're talking about muzzle loaders, you can eliminate the "cushion" wad. Just damp wipe after each shot and use only the over powder wad and the over shot card. If you use anything greasy on the wads, you're more likely to have smoldering than if there is nothing on them. Lubing the "cushion" wad with something containing mostly water will kill smoldering but I don't think you'd want water in cartridges. The so-called cushion wad is mainly useful as a filler or a cleaner in ML shooting. It won't do anything else for you. If you're talking about cartridges, use the wad column (dry) you need to fill the shell. Spray the bores frequently with "moose milk" or your favorite concoction containing mostly water. This will minimize fouling.
