tel1958 Posted August 5, 2004 Report Share Posted August 5, 2004 Hi,You can use a weak solution of sodium hydroxide (Caustic Soda).The water/caustic mix depends on the strength of the sodium hydroxide you buy.I use an Oven type cleaner called KLEENOFF, mix about one teaspoon per pint of warm water.works for me.
