Okay, this is a bit different. I let my wife take one of our home PC's to school where she teaches middle school aged students because the school provided PC's are slow junk. So this year, she has been using one of my custom builds with an AMD X3-720 and Win 7. However, because of the odors of her students, e.g. smoke on clothes, pet odors, perspiration, ripe tennis shoes and all sorts of noxious scents, she has used a potpourri pot to mask the stench and had it sitting beside the PC all year. Now this PC has absorbed the potpourri scents she used to where when you turn it on, the fans belch out a floral pipe tobacco (best descriptor) smell which appears to never dissipate. I tried soaking a cloth in Febreze and laying it inside the PC case in the hope it would help. Now the PC stinks of potpourri AND Febreze. There is no fabric/filter inside the PC, just the usual metal and plastic parts; the case is steel. Any ideas on how to clear the stink from this PC? I am about ready to try the car wash or purging by fire!
