Clean your coffeemaker
Fill your percolator or the water chamber of your drip coffeemaker with water and plop in four Alka-Seltzer tablets. When the Alka-Seltzer has dissolved, put the coffeemaker through a brew cycle to clean the tubes. Rinse the chamber out two or three times, then run a brew cycle with plain water before making coffee.
Clean a vase
That stuck-on residue at the bottom of narrow-neck vases may seem impossible to scrub out, but you can easily bubble it away. Fill the vase halfway with water and drop in two Alka-Seltzer tablets. Wait until the fizzing stops, then rinse the vase clean. The same trick works for cleaning glass thermoses.
Clean glass cookware
Say so long to scouring those stubborn stains off your ovenproof glass cookware. Just fill the container with water, add up to six Alka-Seltzer tablets, and let it soak for an hour. The stains should easily scrub away.
Clean your toilet
The citric acid in Alka-Seltzer combined with its fizzing action is an effective toilet bowl cleaner. Simply drop a couple of tablets into the bowl and find something else to do for 20 minutes or so. When you return, a few swipes with a toilet brush will leave your bowl gleaming.
Drop your dull-looking jewelry in a glass of fizzing Alka-Seltzer for a couple of minutes. It will sparkle and shine when you pull it out.
Unclog a drain
Drain clogged again? Get almost instant relief: Drop a couple of Alka-Seltzer tablets down the opening, then pour in a cup of vinegar. Wait a few minutes and then run the hot water at full force to clear the clog. This is also a good way to eliminate kitchen drain odors.
