clean. I usually soak them in hot, soapy water and then clean them with a wet cloth and cleanser -- the non-abrasive kind -- but often then have to use a Brillo-type pad for tough spots. But even so, then I have to use a knife for tiny spots in corners and unless I'm in a very dedicated mood, I still leave small areas. It's a chore and a half and surely I must have overlooked a product that will make this an easy job. Suggestions?
