That is true. However, make sure to get one containing lye. Some of today's oven cleaner sprays use other chemicals which might not strip the paint or might actually melt the plastic. Oven cleaner is also a pain to use as you have to spray it out which results in a fine spray of very irritating mist (if you're not careful). I prefer using liquids containing lye, such as Castrol Super Clean (or one of the generic versions) or "Strip A Kit" from Hangar 3 Arlee (email: doghaus at montana dot com).
