Consider what needs to be cleaned. If it's just normal dirt, the method below will be fine. If it's crayons or heavy smoke, you will need more- possibly stain-seal primer like kilz, because paint won't adhere to crayon wax and will rapidly discolor over smoke residue and many stains. For example, you can paint over a pencil mark, but not over ball-point pen ink; it will discolor the new paint. You have to seal such things to prevent that.
On most walls, we brush away cobwebs or such, then we lightly sand the wall with a drywall sanding pole, and the sanding does the job. Not only cuts away surface dirt, but it removes paint runs or ridges- all the uneven points that otherwise will telegraph to your new paint. It also opens the surface just enough for a good bond. After sanding, we brush or vacuum away the dirt. If there are any nail holes, gouges or indentations in the drywall, we fill these with lightweight spackle. Then we paint; this process makes the walls come out looking more like new walls rather than repainted ones; it's also fast and easy with the pole sanding tool.

If the walls have been painted, you are cleaning paint. You can use a strong vinegar solution, rinse, then scuff slightly with fairly fine sandpaper. That should set you up for the best bond for your next coat. If the Sheetrock has not been painted, you are cleaning cardboard, and it is very porous. Unless it is obviously stained, I think I would lightly run some sandpaper over it and paint it.

The reason why you paint is because of dirty walls! If your going through all those motions to clean why don't you use a bucket of paint and a roller instead of a bucket of soapy water and a rag, going through the same motions so why not just use the paint. I don't see the need if there's no mildew or grease. Cob webs, dust of any kind or loose boogers just dust them off with a rag or broom. Smoke damage your gonna need a primer, sealer, stain killer, its all in one can, Zinseer makes a great product. Think your wasting too much time on the cleaning part, paint does wonders! good luck

If there is mold or you suspect mold (such as in a bathroom or kitchen) you need to spray (with a cheap pump up sprayer like the bug man uses) a 50/50 solutiuon of water and bleach on the walls to kill it. If you don't, the paint will blister off from the mold. Let it dry and then apply a stain blocking primer (such as kilz) and paint right over it and you should have a very nice paint job.

Need to know whats on them?
Sanding them then dusting them will help. But, if they are very bad....primer will work best.
Also, many bonding agents you could use.....or some call them "Deglosser" which clean AND take the shine/sheen off. Be careful with them...usually harsh on hands, carpet...ect.
Contact me if ya need any further advice or brand names.

Already painted TSP (tri-sodium-phosphate) is a good solution.

I would not worry about it, just apply two coats and forget it.
