how do you clean the wall after sanding drywall , before putting on the next coat of mud?

Damp rag.
Dry wall finishing done right should only need sanding on the final coat.
After the first and second coat just drag the drywall knife over the seam to knock off the high spots.
Your trying to build it up, why sand it off to just reapply more compound?

Joe is right, I use a 8" knife just for this. Before next coat use the knife to scrape off the ridges and lumps.
Then apply next coat. Is only final coat you sand.

yup no sand just scrap, when you do come to sanding i use a broom and brush the walls and take a dry paint brush to get in the corners and tight spots. then shop vac the floor. then put a damp rag on a pole and do a quick once over on the walls again.

That said and if you did get ridges that need to be sanded in your first coats? Shop vac with a wide floor brush attachment. When vacuuming drywall use bags in the shop vac.

Shut off HVAC while sanding, have a cheap box fan blowing out a window after the screens remove.

drywall dust is nasty, Sometimes I will prefer to do a 4th coat and zero sanding... depends on surroundings.
Sometime I do 2 heavy coats and sand.
Also depends on what texture is being applied, but always avoid sanding as much as possible.

in homes i set up a containment with plastic on the floors and plastic on the walls that arent being worked on. plastic off hvac and doorways. i set up an air scrubber. i sand roll up the plastic and toss the dust in the trash.

Depending on the situation Zip poles make a fast and easy containment area.
