From my cursory reading, you'd want both a grit guard at the bottom of the bucket and something else to dry it off than a chammy. A silicone scraper (as the ones used in bathrooms, but in silicone) should be just the ticket. The idea is that you don't want grit or hard surfaces to wear out the non-reflective properties, as you can't "buff it out" as you would a normal looking car.
With this in mind, and although expensive, I would buy Swissvax's "opaque" wax (and precleaner etc.) to protect the surface. It's easier to keep a waxed surface clean. Speaking of which, I'd be slightly worried if my soap/sponge took off colour from the matte surface, as that means it is taking off or rounding off the surface. Matte/"opaque" wax would protect it from that.
I have to say I'm not some perfectionist in this regard, and I could never be a detailer (I don't like shiny stuff, for one), but if one has chosen matte paint, you might as well protect it a bit. Not pamper it or anything, but get a good protective coating on it, as you can't buff anything out. The bonus is, of course, there is no need to buff anything. So it's wax sprayed on (put in bucket water?), and that's about it.
