how can I make my panasonic upright vaccuum cleaner stop smeling bad? Possible pet fecies picked up underneath bed. dried before pickup with vaccum but non the less it stinks so bad and I love my panasonic vaccum cleaner and miss using it. Have to replace belt and bag but want to continue using without the terrible sour smell. thank you. heaven4all@suddenlink.net, or donnacarlisle45@yahoo.com
