On smelly refrigerators
June 26, 2017
| A version of this story appeared in
Volume 95, Issue 26
A recent humorous Newscripts article concerning smelly refrigerators (C&EN, May 8, page 40) prompts me to suggest a simple cure. Cut a large hole in the lid of an empty plastic coffee can. To the can add 100 g of diatomaceous earth. Then add 50 g of conc. sulfuric acid. Stir the mixture with a spoon to evenly disperse the acid. The resulting powder should be free flowing. Stretch a porous cloth over the top of the can and use the cut lid as a retaining ring for the cloth. The odor remover acts by forming nonvolatile “-onium” salts of molecules containing oxygen, sulfur, nitrogen, or double bonds. The odor absorber is placed in the bottom of a refrigerator and is useful for six to 12 months. It works a lot better than charcoal or paraffin shavings.

Corrections:
June 19, page 8: A production error led to a page from the Jan. 9 issue printing in place of the correct page of science concentrates from the June 19 issue. Read the stories missing from the June 19 print edition online at cenm.ag/solarcolors and cenm.ag/fdaopioid.
The power is now in your (nitrile gloved) hands
