Best way to remove disintegrated foam insulation?
I had placed some foam insulation (bought at Home Depot) in between the gap of my window in the open position with the installation of my window AC, and now all of that foam has disintegrated to the point that if it is touched, it turns to dust-like particles and is really messy and gets in the air. I need to remove this disintegrated foam, but I would like advice as to what is the best way to remove it without making a huge mess in my bedroom. I'm not so sure that it would be a good idea to vacuum the foam up with my household vacuum cleaner, and I don't own a shop vac. Does anyone know if it is a hazard to breathe these disintegrated foam particles? I also want to get that AC unit out of the window so that I can do a thorough cleaning in the window where lots of spider webs have formed. I'm not fond of spiders.
Thanks for any advice.
