Stacy,believe me this is a massive job.
Went through this myself.I used Soilex and so did my wife.We each had a bucket and a sponge.I went first,she followed behind.
Washing,wiping,rinseing with clean cold water.
We did twice around and let dry as Steve said.
Primed everything with Kilz and painted.Looks great(used good paint).
House is NON SMOKING now!!Luck
