Good morning~
Some great tips here, though must of the unpleasant smell in my case has dissipated now after several years.
I had not heard that rancid oil from the machine can be a cause. My understanding from the FW Yahoo Group is that it's usually the glue used to adhere the fabric lining to the walls of the case. In any event, I have GOT to remember charcoal for situations like this. Last time, I used a bunch of saved silicon packets and found a little relief with that.
