I made the mistake of inviting a friend over for about 2 weeks. I even stayed with my girlfriend and let him sleep on my bed. The problem? He decided not to shower for 2 weeks. He showered a grand total of one time the whole time he was here despite me telling him to. So he's left this horrible sweaty sour smell in my entire apartment. I've left all the windows open for 3 days, washed my blankets and sheets twice, febreezed everything twice including the carpet... AND IT STILL REEKS OF HIM. I need some advice on how to get rid of this smell because it's killing me. I can't even stay in this apartment and my roommate is pretty pissed off too.
