There are alot of new products out there that are good for this but still requier some elbo greese to get it all off. I like to stick with the good old stand by (Gunk). It does everthing I need it to do. sometimes I will use (Greesed Lighting) if its not to much of a buildup. If you have access to a steam cleaner you can get most of the buildup off with out using a cleaner.
