Had a little gathering tonight and one of my cousin's kids was sick and spent the evening on one of my sofas. Toward the end of the evening she vomited on the furniture, clear liquid, but still. I clean that up with my Bissell Pro Heat, but I'm wondering how long the germs live in the ares she was laying, it's where I normally sit. I'll toss the blankets she was using in the wash. Any suggestions for the upholstery?
