First, flush your water heater once a year. Sediment settles at the bottom and can trap air, causing persistent cloudiness. It’s a simple DIY task (YouTube is your friend).
Second, consider installing a pressure-reducing valve if your home sees high water pressure (above 80 psi). That lowers the chance of trapped air and also protects your pipes.

Third, if you’re a renter, just send your landlord a short text: “Hey, my hot water looks milky. It’s probably just air, but can you check the water heater temp?” It shows you’re proactive without being dramatic.
Fun Fact for Your Next Dinner Party
Milky hot water is actually more common in winter. Colder incoming groundwater holds more dissolved air, which then expands wildly when heated. So if you’re sipping white-looking tea in January, blame the season.
In contrast, summer water—warmer from the start—releases less air. So the cloudiness is literally a seasonal trend. Who knew plumbing had a fashion cycle?
Also, showerheads aerate water intentionally—that’s why some sprays feel softer. That same aeration can make your bathwater look like a latté. Embrace the foam.
