Ideally, when attempting a wash like this you want a collection of good quality microfibre cloths, folded into quarters, so that no one side of the cloth sees contact with the car twice. No matter how clean your microfibre cloth looks coming off the panel there will always be dirt and grit caught in the fibres. This is the advantage of microfibre. It's like a magnet. It picks up a lot. At the same time though, it is an excellent mechanism to transfer grit back onto the panel if you're not careful.
The problem too with using a single bucket is that you're contaminating the wash solution with dirt and grit coming off the microfibre when you rinse it. The dirt and grit swirls around the bucket and re-attaches itself to the cloth the next time you dunk it into the bucket.
If waterless or rinseless wash is your only option, I highly recommend checking out the Garry Dean Method. It is the best way of ensuring there is minimum marring done to the car's paintwork.
See the following video. He better explains some of the things I've mentioned here.
Just a note on this, you don't need to use his Infinite Detailing Juice to use this method. Any waterless/rinseless wash product will work. I personally like Optimum as is has a very high level of lubricity, which is exactly the sort of thing you want for this sort of washing.
