My wonder cleaner is \"CitraSolv\" a biodegradable citrus degreaser. It comes as a concentrate which you dilute depending on the job in hand. Most fantastic result: used neat on the cooker extractor fan filter (a wire mesh like thing!) this immediately dissolved all the built up grease where copious amounts of boiling water & dish liquid had failed! Diluted it is gentle enough to wipe down wooden galley surfaces where greasy finger prints abound - it smells good too.

I love Barkeepers friend. The stuff will clean any stove or pot/pan that you can't get clean. Can be found at most grocery stores, or by larger quantities at http://www.barkeepersfriend.com/products.htm

A good trick for the metal mesh filters is to clean them about once a month (or after heavy use) in the dishwasher. Just put it in with a load of dishes. Sure beats scrubbing.
