(The oven needs a damn good clean and whether I do it or get someone in, the manual says don't try and clean the catalytic surfaces any other way. I actually have one of those Lakeland kits with big plastic bags that you chuck the racks in with a caustic solution + a spray on and leave bottle of stuff for the glass and non-catalytic surfaces. There's also gloves and arm protectors!).
Roasting chickens in it has taken its toll.
