How do i clean the glass window

I've found that a couple of cleaners will work.

You can try Simple Green full strength as it doesn't have any nasty fumes and cuts grease really well.

The other is sudsy ammonia, but I personally can't stand the odor when using this.

Another helpful tip is to warm the oven to about 200 degrees before you clean the glass, as that will help soften the gunk (that's a technical term!) and make cleaning it easier. Just turn the oven off and let it cool for about 5 minutes before you start cleaning the glass with the Simple Green (or the ammonia ugh!)

Now clean away with a decent sponge and paper towels.

Hope you found this very helpful and best regards!

simple green. it's non-toxic and biodegradable, so it's ok to use around food, and it works graet on heavy grease. but if all else fails, use easy-off oven cleaner.
