I have been spoiled with self cleaning ovens for the last 10 years...but my 
main oven's mechanism just broke.  I guesstimate is that it would require 
at least $150 dollars in Sears Service to repair so...( and is that worth 
it in 10 year old ovens) any advice on the best and safest way to clean 
ovens in today's world.  Easy Off was the cleanser used in my previous 
life.  In advance...thanks.
