It is not often that I use my cheap rechargable electric drill but when I needed it two days ago the plastic body had degraded and it was covered in a sticky residue. Today I successfully cleaned it up not with baking soda as recommended on one website (it was mostly ineffectual) nor with isopropyl alcohol, since I didn't have any, but with caustic soda gel which can be bought as oven cleaner. It did rather a good job but of course you must not get this substance on your skin and all traces have to be removed from the article being cleaned.
