Summer is a season of contradictions. The days are long and warm, the pace slows down, and there’s finally time to relax. But summer is also a mess. Sand invades every crevice of your car and home. Sunscreen leaves yellow stains on white shirts and orange rings on collars. Beach towels develop that particular funk that no amount of regular washing seems to fix. And somehow, even though you’re spending more time outdoors, your house seems to get dirtier faster.
Jolie Kerr, the cleaning columnist at the Washington Post, recently published a guide to handling summer’s worst messes, and it’s a reminder that a few targeted techniques make the difference between spending your Sunday scrubbing and actually enjoying the season. Here’s how to handle the main offenders.
Sand: The Gift That Keeps on Giving
Sand has a physics-defying ability to travel. It gets between car seats, embeds itself in beach bag seams, and somehow ends up in your bathroom even if you showered at the beach. The standard response — aggressive vacuuming followed by sweeping followed by more vacuuming — works eventually, but it’s inefficient.
Baby powder or cornstarch is the secret weapon. Sprinkle it liberally on sandy skin, sandy car seats, or sandy gear. The powder absorbs moisture, which is what makes sand stick. Wait a minute, then brush or wipe it off. The sand comes with the powder instead of grinding into fabric and skin.
For car interiors, a stiff-bristled brush gets sand out of fabric seams better than a vacuum alone. Brush the sand loose first, then vacuum. For floor mats, take them out of the car and whack them against a hard surface before vacuuming. The whacking does 80% of the work.
For the house, keep a dedicated “beach towel” that goes straight into a sealed plastic bag after the beach and straight into the washer when you get home. The bag contains the sand and prevents it from spreading to every surface between the front door and the laundry room. This is the single most effective habit change for keeping sand out of your living space.
Sunscreen Stains: The Yellow Menace
Sunscreen stains are caused by avobenzone, the chemical that absorbs UVA rays. When avobenzone mixes with minerals in hard water during washing, it creates yellowish-brown stains that set into fabric. The stains are particularly visible on white and light-colored clothing — which is, of course, what most people wear in summer.
The fix depends on when you catch the stain.
For fresh sunscreen stains, apply liquid dish soap directly to the stain and rub the fabric against itself. Dish soap is designed to break down oils, and sunscreen is essentially an oil-based product. Let it sit for five minutes, then wash in the hottest water the fabric can handle. Hot water is important — it keeps the avobenzone from binding with minerals.
For set-in stains that have already been through the wash, you need an oxygen bleach soak. Fill a bucket or sink with hot water, add a scoop of oxygen bleach (OxiClean or equivalent), and submerge the stained garment. Let it soak for at least four hours, ideally overnight. The oxygen bleach breaks down the avobenzone-mineral bonds that have already formed. After soaking, wash normally.
One prevention tip worth knowing: if you have hard water, add a water softener like Calgon to your laundry when washing clothes with sunscreen residue. It prevents the mineral reaction that causes the staining in the first place.
The Musty Beach Towel Problem
Beach towels face an unusually difficult set of conditions. They get wet with salt water, which doesn’t fully rinse out in a standard wash cycle. They sit damp in a beach bag for hours before reaching the washer. And they’re often made of thick cotton that takes forever to dry completely, creating ideal conditions for mildew.
The musty smell that develops isn’t dirt. It’s bacteria and mildew feeding on residual organic matter in the towel fibers. Regular detergent doesn’t reliably kill them, especially in cold water.
The fix is vinegar. Add one cup of white vinegar to the rinse cycle instead of fabric softener. Vinegar kills the odor-causing bacteria, dissolves mineral buildup from hard water, and leaves no residual smell once the towels are dry. Do not use fabric softener on towels — it coats the fibers with a waxy residue that reduces absorbency and traps odors.
After washing, dry towels completely. If your dryer has a sanitize cycle, use it. If line-drying, make sure towels are in full sun — UV light is a natural disinfectant and the heat helps kill remaining bacteria. Towels that feel slightly damp after the dryer cycle need more time. Put them back in.
For towels that have already developed a persistent funk, pre-soak them in hot water with one cup of vinegar and a quarter cup of baking soda for two hours before washing. The combination breaks down the biofilm that bacteria build on towel fibers.
Sweat and Deodorant Residue
Summer means sweat, and sweat means two problems: odor and residue. The odor is caused by bacteria breaking down sweat on fabric. The residue — the crusty white or yellow buildup on shirt underarms — is a combination of sweat, deodorant, and dead skin cells.
For the odor, the key is washing athletic and summer wear as soon as possible after wearing. Letting sweaty clothes sit in a hamper for days gives bacteria time to multiply. If you can’t wash immediately, at least hang sweaty clothes to dry before putting them in the hamper. Dry fabric is far less hospitable to bacteria.
For deodorant residue, pre-treat the underarm area of shirts with a paste made from baking soda and water. Rub it in gently with an old toothbrush, let it sit for 15 minutes, then wash normally. The baking soda is mildly abrasive enough to loosen the residue without damaging the fabric, and it neutralizes odors at the same time.
For white dress shirts that have developed yellow underarm staining over time — a common summer problem for anyone who wears button-downs — the same oxygen bleach soak that works on sunscreen stains also works here. The yellowing is caused by a reaction between aluminum in antiperspirant and proteins in sweat. Oxygen bleach breaks those bonds.
Coolers and Beach Gear
The cooler that held your picnic last weekend shouldn’t still smell like it. Rinse coolers immediately after emptying them, but the real cleaning should happen with a bleach solution: one tablespoon of bleach per gallon of water. Fill the cooler partway, close it, shake it around, then let it sit for five minutes before rinsing thoroughly. The bleach kills whatever bacteria survived the rinse water. Let the cooler dry completely with the lid open before storing. A closed, damp cooler is a mold incubator.
Beach toys, snorkel gear, and sand buckets should be rinsed with fresh water immediately after use. Salt water is corrosive, and dried-on salt crystals are abrasive. A five-gallon bucket of fresh water in the garage or on the patio makes this easy — dunk everything on the way in from the car, then let it air-dry in the sun.
A Realistic Summer Cleaning Routine
The goal of summer cleaning isn’t perfection. It’s containment. You’re not trying to maintain a spotless house through beach season. You’re trying to make sure the mess from one weekend doesn’t compound into a problem that ruins the next one.
The efficient approach is to clean the entry points. The area between your front door and your laundry room, and the area around your back door or patio entrance, see the most summer traffic. If those zones are clean, the rest of the house stays manageable. A quick evening sweep of these areas — five minutes, no more — prevents sand from migrating to every room.
For families with kids, a “de-sanding station” by the door works wonders. Keep a large plastic tub or a small inflatable kiddie pool just outside the entrance. Everyone rinses feet, shakes out towels, and drops sandy items before coming inside. It sounds fussy, but it takes 30 seconds and saves 30 minutes of vacuuming later. Some families keep a pump sprayer filled with fresh water by the door for the same purpose — quick rinse, towel off, enter.
If sand has already migrated throughout the house, don’t try to clean it all at once. That’s how you lose an entire Saturday. Instead, run a cordless vacuum for five minutes in the highest-traffic rooms each evening. A cordless stick vacuum that lives in a charging dock near the kitchen or entryway gets used far more often than a heavy canister vacuum stored in a closet. The barrier to use is everything. If you have to drag a vacuum out of a closet, unspool the cord, and plug it in, you’ll do it once a week. If you can grab it off the wall and be done in three minutes, you’ll do it daily. The difference in total sand removed over a summer is dramatic.
One more thing about floors: summer means bare feet, and bare feet mean foot oils and sweat on hard floors. A quick microfiber mop pass — the kind with a spray trigger built into the handle — every other day keeps floors from developing that sticky summer film that builds up from bare feet, humidity, and open windows. You don’t need a full mop-and-bucket routine. Thirty seconds per room with a spray mop is enough.
And here’s the permission you might need: it’s okay if the house isn’t perfect. Summer is short. The sand will still be there in September. So will the sunscreen stains. A few targeted habits — the dedicated beach bag, the vinegar rinse, the post-beach rinse bucket — keep the season enjoyable without letting the mess take over your life. Everything else can wait.
