Had a apt manger call me today to clean a apt that in her words "the guy smoked a lot and the washed the walls and were tryin to get the smoke out so they could rent." So I get there and the living was orange, except for where the furniture was. So, I mixed up some O2 and hot sause, 400 psi, and 230 temp. vac, pre spray, rake in, (would love to have a buffer) extract. Looked really good. all came out except for the really bad areas around the furiture legs. What would you have done? Could I have used some thing additional? This was my first time doing something like this. I did think about spraying some somke out on the bad areas before the pre spray.
