Your comment on the smell going away is odd; do you mean that once the smell of smoke went away the other smells of urine and stale beer then dominated?
If so, how did they then go away?
Do only smokers pee and spill beer or is it that you now spend so much time there that you have become oblivious to the smell?
There's these two magical ingredients called soap and water. You mix them together, rub them on surfaces and dirt and smells are removed.
