find shit with good alcohol in it like hair spray and shit cause it literally eats up the weird smells and shit. but dont do more than that or else the room smells like shit. have one fan moving the air around in the room and one more props against the window blowing OUT of it so it sucks the air in from the room going out the window.
and
when u want to toke in ur room or something make one of those things u blow throught with teh TIDE bountry sheets stuffed in it. or have a fan going OUT the window...
