Summary in progress. (sale on ebay)

A Guide to the Unknown collects articles written for a general audience to explain how statistics were used in research, to improve understanding.

Each essay is listed below, and summarized.

How to Clean Gas Range Burner Grates

For each grate:

1 gallon zipper plastic bag

1/4 cup ammonia

Put the grate into the bag, and add ammonia.  Seal the bag and wait 12 hours.  Remove grate from the bag, and clean off grates with a sponge.

I read this here and here.  I can verify that it works.

Another way I tried to clean grates was with a soak in washing soda and hot water.  This worked somewhat, and helped reduce the grease, but the ammonia method above was cheaper and better.

Ammonia works on even the blackened, hardened fats. It didn’t clean mine entirely, but still did a visibly good job.
