Thanks for all the great advice. I enclosed the machine in a large lawn and leaf trash bag and set off a roach spray bomb inside the bag. I left it on my back porch for a week. When I was brave enough to open it, I saw about 6 dead roaches (and some kind of worm!). I cleaned it thoroughly inside and out, then oiled it well. I then tested it, using all the stitches and functions and - amazingly - it works fine. I still don't think I want this machine, though. Every time I look at it I remember the horror of the roach nest.




Thanks again for the ideas, I appreciate all of you.
