I have a remedy! It may not be the best and for sure you don't want to get this on your machine's finish or decals! There is nothing quite as good for getting rid of offensive odors as cotton balls soaked in some 100% pure vanilla flavoring (and/or almond extract). Both the vanilla and the almond extract smell great! Just put the soaked cotton balls in a small open container and sit it in the case! Again, be very careful -- DO NOT get the vanilla or almond extract on the finish of the machine -- these extracts contain ALCOHOL which will damage or destroy the finish!
