No. 13 is water-based cleaner, not really a solvent - so essentially you are still using water (along with other additives). I do use No. 13 for a quick cleanup at the range, but still prefer to use water with a touch of soap for a full cleaning when I get home, as I believe it does a more thorough job of rinsing out places where a patch might not necessarily make contact with. I shoot sidelocks though, which have a small flash channel from the nipple area into the breech - no such worry for an inline of course but I bet there are still areas of the breech that a patch doesn't reach. I suppose you could also remove the breech plug and clean that with hot water, and simply use wet patches to swab the bore.
