You're fine, no worries. Just make sure you keep it away from the burners. You don't want any gas not burning.

I clean my stove. I use SoftScrub or non-abrasive Comet or something like that if something is tough/burnt on, but I clean pretty much every time I use the stove.

Your roommate and you need to stop talking about the aluminum foil on the stove; otherwise, people will think that you're married. Either he lives with the aluminum foil, or he cleans the stove; end of discussion.

Melting Point:
660C (1220F)


a normal stove can't get to 1220F let alone 4221F

it depends on the foil. if its that thin cheap crap made by shurfine it will melt on a stove top. ive done it. heavy-duty Reynolds wrap is more durable and if left long enough will still burn a hole in it.

If you put the foil under the element just keep a safe distance from where the element plugs in. That's 240 volts, you don't want that doing a parrallel arc since that will be nasty...

The electric element is actually a casing that's at ground potential. The resistance (heating) wire made of nickel-chromium alloy (nichrome) is much thinner and sits in the middle of the casing. High temperature dielectric refractory not much different than diatomaceous earth surrounds this wire. This is why it takes long for the casing to get hot - glowing hot on HIGH - after first turned on.

It's true that Al foil can make its way near the lugs which have 120VAC respective to ground which can cause a fault. On newer ranges with AFCI protection it will trip faster than you can say arky sparky. On regular ranges though it can arc and start a nasty fire.

Sometimes larger elements in the bottom of ovens can fault themselves and burn along the outer casing. If allowed to continue the results can be spectacular! Text

Some believe the foil can work as a reflector collimating the longwave IR causing the element to overheat and fail prematurely like above. I have no idea if this is really the case.

I'm not sure if you've answered these questions or not-
1. Gas or electric?
2. Where are you putting the foil?
3. Why are you putting foil on your stove?

1) Gas

Its of this nature, although the layout is different.
I put it in the white area, and around the knobs on the right in case a nasty spill appears I don't touch the burners at all.

thats exactly what i would do



3) Minimize scrubbing I need to do on the Stove. This way, one can throw away the foil after 2-3 months and put on new foil. In a place where no one wants to clean (and I sure as hell don't want to clean after their mess that they ignore) this is a Godsend.

the foil doesnt even touch the food.

That is a sealed gas burner. Now I'm really confused. How do you keep a spill from going underneath the foil? I hope you don't caulk the foil down. You might as well coat the grate in foil and make a hat while you're at it. I would think the aluminum would scratch the shit out of the enamel over time.

We all know an MSDS can just say "no info" across the board. While it contains some hazard information, it can be anywhere from 1 page of nothing to 12 pages of detailed stuff explaining all possible problems.

That's simple corrosion. You can corrode a lot other things. You know canned foods essentially corrode the tin in cans? It's just that tin is relatively acceptable by the human body.

I'm confused as to what putting aluminum foil on the coils will even do for you. Anything that gets on them will just burn off anyway. I think everyone puts aluminum foil under the coils to make spills easier to cleanup, but it never gets that hot underneath.

Sounds like it. What's the point? I think I just let whatever falls in burn into carbon and bought new cheap ones at the supermarket at the end of the lease.

So you won't have to spend 1+ hr cleaning them with Ajax/Comet and Brillo pads?
It's easier and cheaper to put foil in the bowl and just change it every few months.

The oven can't hit those temperatures, but the flames of natural gas can hit ~2000 degrees C.
