I loaned my carpet steamer to a friend a couple of weeks ago. She was taking her puppy to the Vet today and had told me she was gonna bring my steamer home. Got a message from her tonight that they'd just left the Vet and he'd kept their dog...she has PARVO! Anyway, she said she bring the steamer hime in the morning. Now, I'm concerned if I want the steamer here...around MY own dogs (one of which is a puppy). Would it be dangerous? Is there some way to disinfect the steamer..or do I need to do that?
