Dirty burner grate & drip pan?

My wife found replacement drip pans online for our stove the other day because i am a mess in the kitchen and they are filthy. When she showed me the price i needed to look and see if I can find an alternative first. I read about every miracle cleaner that would do the trick (many I have tried before)until one post suggested placing the burner grates & drip pans in the oven during self clean mode. Holy Cow! they are SPOTLESS the grates and drop pans are totally clean and all i had to do was stink up the house for 3 hours. I believe it works so well that I would borrow a self cleaning oven before I ever try and scrub, soak, scrub those things clean ever again. This may not be authorized according to the oven manufacturer but as good as it looks i cant complain.
