Here’s the thing nobody tells you: a boil water advisory is terrifying enough without adding dirty underwear to the mix. I tried to logic my way through it. Is water dangerous to clothes? Or only to my stomach? Spoiler: I’m a writer, not a scientist, so I immediately texted my friend Karen, who is both a microbiologist and a mom of three. She didn’t laugh, which means it’s a real question.
Turns out, yes, you can do laundry under a boil water advisory—but only if you’re smart about it. And no, you don’t need to boil your jeans on the stove. (Though I admire the commitment.) The key is temperature and contact time. Modern washing machines can hit 140°F, which is hot enough to kill most bugs if the cycle runs long enough.
Hot Water Is Your BFF
If you own a washing machine with a “sanitary” or “heavy duty” cycle, you’re golden. Set it to hot (at least 130°F) and add your regular detergent. The combination of heat and soap actually does a better job than boiling water alone—soap breaks down the germs’ outer shell, and heat finishes them off. Trust the science.
But what if you’re like me and have a cheap machine that only has “warm” and “cold”? Don’t panic. You can still do laundry, but you need to add a sanitizing step. Bleach is your friend here. For whites, add ½ cup of regular chlorine bleach after the wash cycle starts. For colors, use a laundry sanitizer like Lysol or OxiClean. Read the label—they’re designed to kill bacteria even in cool water.
And here’s the ironic part: your clothes are actually cleaner after a boil water advisory wash than they usually are. Because who runs a “sanitary” cycle on a normal Tuesday? Nobody. So pat yourself on the back.
