I need to replace the insullation around my dishwasher because of a rodent problem thats caused it to really smell. Can I use regular fiberglass insullation from Home Depot or is it necessary for me to order the high priced stuff from an appliance repair parts site?
As gregzoll said, you don't want regular fiberglass batt there, it would send out little glass slivers to the kitchen while the motor is running. Hard on the lungs- people, dogs, cats, birds, iguanas, etc. to get in the return air of furnace and give all sorts of health problems (Fiberglass is a suspected carcinogen and carries a hazard warning label).

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?
