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

Wow, that sounds like a lot of work! I can't help you as I still have a little ol' Broan that uses mesh filters, which I put in the dishwasher. Is your hood working properly, meaning is any grease getting to the cabinets, ceiling, etc?

I don't have a tea kettle but I would assume that if you had a tea kettle with just a little bit of water sitting on the stove when not in use, bacteria, dust and other items present in the air will fall in the kettle and can create a slime factory over time if not cleaned. I personally use an electric tea kettle (British upbringing) and now graduated to a Japanese Airpot. I love my airpot. When I used an electric kettle, I never left water in it and washed it out weekly. I have filtered water and never had a problem with the tea kettles. I clean my airpot out weekly when I have no water left in it. Good luck!

2. Protect Oven: The excessive debris building up on the bottom of appliance can be prevented by the oven liners and washed and reused time and again. This is begging for trouble when those liners melt. I don't know of a single oven manufacturer that doesn't say, "Don't use liners!". You can see some of the threads here for more on the problems they create. Also, for #4, randomly pouring drano et al is foolish, wasteful, and not good for the environment. Keeping a plunger available for if you have a problem and using common sense like not pouring hot fat down the sink are both better ways to avoid clogged drains. But working methodically to avoid going back over where you were is a good recommendation.
