place a dish of vinegar in the room on the floor int he center. close any windows and doors. wait one hour. go inside and sniff. come back here and thank me.

you're welcome.

yes, do some dusting

I have a backroom located 15 yards from my parent's house. No windows, wooden outside, plastered material structured in the inside that make up the wall. Anyways, my room has this dust stench that gives me huge headaches, the one where you walk into a room and some sort of dust particles make your nose tingle. How do i replace this stench with actual "air"? I have been told to get an air filter but I am on a budget right now and i like to use my right as soon as possible. Can a portable fan be useful for this situation? Leaving the door open, fan everything out? Any suggestions?
