I take a couple of Clorox brand Handi-Wipes. They are highly absorbent, dry in a few minutes, last through several launderings before being tossed. They also weigh next to nothing. 0.6 oz for the pair, and they dry so fast that I never have to carry them wet. Since I also use them for cleaning kitchen counters (far more sanitary than a sponge), I always have them around the house anyway.

Like most of the others here, I'm happy with what I use and see no reason to spend money on anything different. I really don't think that this is where your market will be.
