The detergent added to the wash breaks up the surface tension and allows the wash to seep more deeply into crevices it might otherwise fail to reach. Some add glue to the mix to add durability. I prefer to do a top coat of clear spray after the wash is dry.
Glue can also be used to increase the surface tension, if you want to colour the area as well as shade it, I think it might decrease the shinyness too.
Detergent as rightly pointed out helps to increase the flow of the paint so as it doesn't form air bubbles which then don't get inked.
Up, up and away!
I wouldn't recommend adding glue to washes - unless you are using a junk brush you don't care about. That would be a quick way of destroying your brush.
That said - there are many different ways to get even coverage. Believe it or not the easiest is to simply add water and not overload your brush. If you overload the brush you tend to get pooling. If you wick off the majority from the brush and use several passes you can end up with nice even glazing...
If you want to add stuff to break the surface tension there are indeed many ways to go about it. A touch of soap/dish detergent will work as well as any number of professional paint extenders and mediums.
Myself - I use a mix that was recommended that consists of about 40% water, 15% liquitex extender, and about 45% future floor wax. (these are rough estimates...).
I posted this in the other thread and some people found it helpful so I will post it here too.I agree with slorak that you might need some sort of liquid extender if you are mixing custom ink color to make sure they stay liquids longer. I have found that simply a drop of vallejo glaze medium along with some water will do the trick. If you don't want you ink to shine as much adding a small drop of a similar color paint can do the trick. For whatever reason even the littlest bit of paint drops the sheen of inks down considerably.
Instead of adding detergent to break surface tension you can use it to your advantage to get into the crevices better. You can then use a second brush that is dry to soak up the excess. Use slow spinning motion and wick away the extra ink. I have found that this technique works great and saves you from making errors when mixing detergent and offers you more control.
Not to mention - if you are that worried about the shine (and in most cases different paints have different levels of shine to begin with)... you can always use a matte or satin varnish to tone it down. Dullcote or any other equivalent should work marvels for killing any unwanted shine!
I use future floor wax for my washes. It works great!
