This is going to sound completely off the wall, but for leather cleaning, go to a commercial laundromat and just put the leathers in the machine. Seriously. Of course, take your amour out, but that's what a bunch of us do here. Remember that we ride in the rain all the time and wet leathers are nothing. If you think of all the sweat you put in them too, getting leathers soaked is not a big deal. You just have to replenish the oils after.
So after the wash, we let them dry for 2 to 3 days. Once dry, we give them a good coating of mink oil. You can find mink oil at any shoe place, and sometimes even safeway in the shoe polish section. Give a good coating of mink oil, wait 2 days and then wipe off the excess. Leather will be supple again and clean.
