A few people have asked how to clean the grooves where the lid clips in on the tmx. Mine is a mess after a weekend of making jam, biscuits, the varoma etc. I use a damp chux cloth worked through the groove - similar to flossing. I then run a dry tea towel through it. I got this idea from a friend and it works well so I haven't tried any other way. Some people will use small brushes to clean the groove then dry with a dry cloth.
