I tried all of the solutions mentioned here for the smell, which I read somewhere is rancid oil. Nothing totally took the odor away. Putting the case in the sun worked the best. I do keep an absorbant 'stone' in mine, but it still smells, though not as much as when I first purchased it. I wonder if there are solutions for rancid and old oil odors in other situations. What about containers that held rancid nuts, such as peanuts? Also, I am thinking about pictures I see of people using wood plant flooring from or in old mills for new households. The Featherweight cases are made of wood so the oil must have soaked into it in some way, from machine itself or oil container. Does anyone clean old
oil soak rags?
I hadn't thought of using a lamp. Perhaps a hairdryer would work. I have one of the original home hair dryers from the 1950's. It has a hood attached to a hose coming off a round motor. I never use the hood, but the hose and heater sure works great when defrosting my deep freezer.
I am not into antique for antique sake so I may purchase a new replica for myself. My machine, itself does not have an odor.
