A handlheld clothing steamer is just about perfect for the job and can be had for a few dollars at a second hand store. When sanitizing an area, fill the reservoir with 30% hydrogen peroxide and plug in the device. Spray down your container when the element is fully warmed. Be warned: a small amount of H2O2 may be left in the element from previous uses and can spray without warning during heat up. Also… don’t use the vaporizer to steam your drapes afterwards.
