There are more things you can do with Alka-Seltzer than just quiet an upset tummy:
Clean a toilet. Drop in two Alka-Seltzer tablets; wait twenty minutes, brush, and flush. The citric acid and effervescent action clean vitreous china.
Clean a vase. To remove a stain from the bottom of a glass vase or cruet, fill with water and drop in two Alka-Seltzer tablets.
Polish jewelry. Drop two Alka-Seltzer tablets into a glass of water and immerse the jewelry for two minutes.
Clean a thermos bottle. Fill the bottle with water, drop in four Alka-Seltzer tablets, and let soak for an hour (or longer, if necessary).
Remove burned-on grease from a pot or pan. Fill the pot or pan with water, drop in six Alka-Seltzer tablets, let soak for one hour, then scrub as usual.
Unclog a drain. Clear the sink drain by dropping three Alka-Seltzer tablets down the drain followed by a cup of Heinz White Vinegar. Wait a few minutes, then run the hot water.
Get short-term relief from nicotine withdrawal symptoms. As long as you're not on a low-sodium diet or have peptic ulcers, drink two Alka-Seltzer tablets dissolved in a glass of water at every meal.
Soothe insect bites. Dissolve two Alka-Seltzer tablets in a glass of water, dip a cloth into the solution, and place the cloth on the bite for twenty minutes.
