Don't paint it unless it's a paint for high heat, otherwise it will cause problems down the road for the future owners. You might try one of those Mr. Clean Magic Erasers. Might also try a piece of paper towel folded to the right size, soaked with a degreaser & let it sit on the area for a while. Good Luck.

In the old days --- uh-oh, there's the chronic old fart warning klaxon -- we used to heat the oven to warm (about 200F), shut it off, put in a bowl with a cup of ammonia, and leave it sit over-night. Then, toss the ammonia down the sink, and scrub the walls etc. with a scrubby and dish detergent. There were commercial (i.e., restaurant and institutional grade) oven cleaners but they were incredibly caustic and a big problem for anything that was not stainless steel. (Old fashioned Lutefisk might have smelled worse, but it was a pretty close call!) The instructions for my NXR say not to use "commerciaL" oven cleaners and I'm pretty sure (and have been told) that this means the actual "commercial" products not the residential grade stuff like Fume-free Easy Off, I've used the latter several times with no apparent ill effects (basically after the massive cooking marathons of Thanksgiving and Christmas). "No ill effects" means that I have not stripped the shine off the oven lining. As I understand it it, the warnings about not using "commercial" oven cleaners refer to the restaurant/insitutional grade products, not the "residential" products like Easy Off. (Do be aware, however, that some Easy-Off products are pretty d@*& strong. So, during your stove's warranty period, you want to use the "gentler" stuff like Fume Free rather than the Extra-Strength. What I do most of the time is a modified version of what Whirlpool calls "Acqua-lift."Basically, I get the oven very hot and let a bunch of water vapor in. (Typically, by putting a CI pan of water in the bottom of the oven when I'm baking bread.) Once the oven walls have cooled past the too-hot-to-touch stage, I scrub the walls using Dawn and blue scrubbie. That usually takes care of the problem. When it does not, I use the Fume Free Easy-Off. This post was edited by JWVideo on Fri, Apr 25, 14 at 23:48

I highly suggest before you attempt to take apart your oven to clean the inside of the glass that you review your owners manual. I had the same issue with my Whirlpool wall ovens and I thought how hard could it be to take apart and clean. Please note my ovens are over 20 years old. I was able to remove the door and get to the inner glass pane but I failed to realize that the inner and outer glass panes are sealed and once the seal is broken its near impossible for a lay person to put back together. Well long story short I am now in the process of replacing my double ovens. According to my Appliance Guy some ovens cannot be opened to clean the inner glass panes. His resolution was for any future oven call in for service and let them replace the glass. If I had only known!!! But again the ovens were 20 years old and really needed to be replaced, but if I was thinking I would have waited until after Thanksgiving!

Thank you Trailrunner for your sage advise! I trust your methods implicitly, as I'm sure you know your way around the kitchen much better than I do, and cleaning up is always such an important part of process. I know your kitchen doesn't just look pretty, but sees alot of action, as I've seen the culinary creations you've turned out! You're right though, I plan to follow your suggestion of cleaning up spatters when they're fresh (so much easier), and will try those products you mentioned. MileHighDiva and cloud_swift- Just trying to keep the repairman away...and maybe will try the self-clean feature every once in awhile, but will try to avoid if I can, since I know how hot it gets during the cleaning cycle when I'd use it on my old Kitchenaid range. And yes, those french doors are really neat. I saw them on an episode of "Little People" when Jen and Bill were picking out the aplliances for their new home, but even for an average size person they make alot of sense. circuspeanut...my luck, I'd cut myself with the razorblade. Yes, the interior is dark-speckled enamel, but probably not the heavy-duty, high quality of your vintage range! They don't make anything to last anymore... PS I'm saving these tips by writing out and placing safely inside my copy of "Hints from Heloise", I inherited from my dear mother. Thank you all.
