I was just gifted a bag of beautiful (mostly) 40s from a hoarder house. These particular pieces were in a garment bag, the only reason they didn't face the holey moth eaten fate the rest of the (once) gorgeous pieces in the closet faced. They are still covered in 30+ years of dirt, dust, and probably more. Normally I would steam pieces I bring inside to get rid of the odor, dust mites, and hopefully killing any freeloading creatures that caught a ride in the process. I know I have a lot of risky cleaning ahead of me so the last thing I want to do is make it harder on myself. SO, my big question is.... is steam going to set these stains?
