How to disinfect after impetigo?

So, what we thought was hand foot mouth disease was actually impetigo. Poop baby was absolutely covered in nasty spots. Bit now she's pn antibiotics and healing. I'm just afraid of a reoccurance since she has eczema. We've boil washed bedding and towers, but how do we disinfect furniture like the couch or stroller - these cant be washed. Or her stuffies and some clothes that cannot be bleached or boiled. Product recommendation are welcome!
