The washes look good, Reinhard - looks like you'll be showering alone. 
Adding dish detergent to the washes is a good idea, but you need only a couple of drops per half-litre or so. I generally use washes in a similar manner, but use a good-size brush (1/2", 1", or 2") depending on the size of the structure. In most cases, it's applied very liberally at the top of the wall, then the building is set on several sheets of newspaper and the wash allowed to run down the walls. The brush can be used to add a little more in places where the natural flow misses. As the newspaper becomes saturated with the run-off, the structure should be moved to a drier portion, and, as the drying process follows the wash down the wall, the brush can be used to remove the excess which collects at the bottom - left in place, it usually creates very distinct and irregular lines which don't look too realistic.
You can apply successive washes (same as the first or of different colours) to build-up the weathered appearance, but you can also allow the structure to lie flat for all- or a portion of the drying time. Another option is to prop up the building at an angle to lessen the rate at which the wash proceeds down the wall - this allows more of it to dry before reaching the bottom.
