Chlorine is a gas dissolved in water, and it wants to escape. Fill a pitcher and leave it on the counter uncovered for 24 hours—about 90% of the chlorine will simply say goodbye. This is the original “influencer hack,” used by grandmas and fish-tank owners since forever.
For hot water—say, for your morning shower—you can speed things up dramatically. Boil the water for 15 minutes, and the chlorine vanishes like weekend plans before a Monday meeting. Just let it cool, and you’ve got neutral, pool-free water for your tea or pasta.
Pro tip: If you’re in a rush, try the aeration method. Pour water back and forth between two pitchers a few times—the agitation releases the gas instantly. It’s a mini arm workout with a side of chemistry.
