currently having to put up with people that have very strong BO smell- won't go into too much detail- there is nothing I can do about changing the fact that they smell- but I need a really strong, odour neutralising air freshener to spray in my - fairly large room- all windows are open to aid the airing - but I need to smell fresher again fairly quickly- no option to burn candles etc - I really do need something quick and chemical to help- what are your recommendations?
