Summer laundry comes with its own challenges. It shows up damp, sandy, sunscreen-smeared, and smelling faintly like a pool noodle. Swimsuits get stretched. Rash guards hang onto sunscreen. Beach towels bring home half the shoreline. Swim bags somehow become their own little weather system.
The good news? You do not need a complicated routine to keep summer gear clean. You just need the right timing, the right detergent, and a few don’ts that are worth following unless you enjoy replacing swimsuits every July.
Rinse First, Wash Later: Why Timing Matters
The best thing you can do for summer gear happens before it ever reaches the laundry room: rinse it. After the beach or pool, rinse these items as soon as you can:
- Swimsuits
- Rash guards
- Beach towels
- Swim shirts and trunks
- Swim bags
- Anything covered in sunscreen, chlorine, salt, or sand
Timing matters because chlorine, salt, sunscreen, sweat, and body oils do not politely wait around. Chlorine and salt can be rough on elastic fibers, sunscreen likes to cling to fabric, and sand has a habit of working its way into towels and even your washing machine.
A quick rinse in cool water helps remove the worst of it before it settles in. You do not need to fully wash everything on the spot. Just rinse, gently squeeze out excess water, and hang items to dry if you are not washing them right away.
How to Wash Swimsuits Without Stretching Them Out
Swimsuits are made to stretch, but they are not made to survive laundry chaos. Heat, harsh washing, and too much detergent can all shorten their lifespan. Here’s the simple method:
- Rinse the swimsuit in cool water after swimming.
- Pretreat any sunscreen or body oil spots before washing.
- Wash in cool water on a gentle cycle, preferably in a mesh bag.
- Use a small amount of detergent that rinses clean.
- Air dry flat or hang away from direct high heat.
For detergent, keep it simple. Charlie’s Soap Natural Laundry Liquid Detergent is a good fit when you want a low-sudsing, fragrance-free wash that cleans without leaving behind extra residue. Swimsuits sit close to the skin, so residue-free cleaning is not just a nice bonus. It is kind of the whole point.
If you prefer powder, Charlie’s Soap Natural Laundry Powder Detergent is another strong choice for regular summer laundry loads, especially when you are washing towels, T-shirts, swim trunks, and other sturdy summer items together.
How to Remove Chlorine Smell From Swimsuit Fabric
If you are trying to remove chlorine smell from swimsuit fabric, start with a cool-water rinse right after swimming. That first rinse helps dilute chlorine before it settles into the fibers.
For a lingering smell, soak the swimsuit in cool water with a small amount of detergent for 15 to 30 minutes, then wash gently. Avoid hot water, bleach, and heavy fragrance boosters. Those can make things harder on elastic fabrics, and fragrance can cover odor without actually solving the cleaning problem.
A detergent that rinses clean helps because leftover detergent can trap odors over time. That is especially true with low-water and HE washers, where using too much detergent can leave gear feeling less fresh even after a wash.
If your swimsuit still smells like a public pool lobby after washing, check two things: how quickly you are rinsing it and how much detergent you are using. More detergent is not always cleaner. Sometimes it is just more stuff to rinse out.
How to Wash Rash Guards Without Wrecking the Stretch
Rash guards are usually made with stretchy synthetic fabrics, which means they need a little more care than the average T-shirt. Here’s how to wash rash guards safely:
- Rinse them in cool water after each use.
- Turn them inside out before washing.
- Wash on a gentle cycle with similar lightweight items.
- Skip fabric softener.
- Air dry instead of using the dryer.
Fabric softener is one of the biggest mistakes people make with stretchy summer gear. It can leave a coating behind, which is not great when the fabric is designed to stretch, move, and sit directly against skin for hours in the sun.
Sunscreen Stains on Clothes and Swim Gear
Sunscreen stains on clothes can be sneaky. Sometimes they look like greasy marks. Sometimes they show up later as yellowish stains, especially around collars, cuffs, straps, and waistbands. The trick is to treat sunscreen like an oily stain, not a mystery.
Try this:
- Gently blot excess sunscreen. Do not rub it deeper into the fabric.
- Rinse the back of the stain with cool water.
- Work a small amount of detergent into the stained area.
- Let it sit for 10 to 15 minutes.
- Wash in the warmest water allowed on the care label.
Do not use chlorine bleach on sunscreen stains. It can interact poorly with certain sunscreen ingredients and may worsen discoloration on certain fabrics.
For family beach loads with sunscreen, sweat, and body oils, Charlie’s Soap Natural Laundry Liquid Detergent is especially handy because it is easy to apply directly to spots before washing. Keep the amount modest. The goal is to clean the fabric, not overwhelm the washer with extra detergent.
Sandy Towels Need a Shake, Not a Shortcut
Beach towels are the golden retrievers of laundry. They come home wet, happy, and carrying evidence of every place they visited. Before washing sandy towels, shake them outside. Really shake them. Then let them dry before shaking again if they are still damp and packed with sand. Wet sand clings to fibers, and your washer does not need that kind of relationship.
Once the extra sand is gone:
- Wash towels separately from swimsuits and rash guards when possible.
- Use warm water if the care label allows.
- Avoid overloading the washer.
- Use the right amount of detergent, not extra.
- Dry thoroughly before storing.
If towels come out stiff, musty, or less absorbent, the issue may be detergent buildup, fabric softener, hard water, or simply too much product in the wash. Charlie’s Soap Natural Laundry Powder Detergent is a solid choice for towel loads because it cleans without optical brighteners, perfumes, or fillers.
If hard water is part of the problem, Charlie’s Soap Booster and Hard Water Treatment can help your detergent work more effectively. Hard water can interfere with cleaning, especially on towels that already deal with sunscreen, sweat, and outdoor grime.
Swim Bags Deserve a Wash Too
Swim bags are easy to ignore because they are not technically clothing. Unfortunately, sunscreen residue, damp towels, snack crumbs, and mystery grit do not care about categories.
If the care label allows machine washing, empty every pocket, shake out sand, and wash the bag on a gentle cycle with cool water. Use a small amount of detergent and air dry completely before using it again.
If the bag is not machine washable, wipe it down with a damp cloth and a small amount of detergent, then rinse with a clean, damp cloth and let it dry fully.
The biggest rule with swim bags is simple: do not store damp gear inside. Hang the bag open after each use so moisture can escape. A closed wet bag is where freshness goes to reconsider its life choices.
What Not to Do With Elastic Summer Fabrics
Swimsuits, rash guards, and stretch swimwear do not need aggressive cleaning. They need smart cleaning. Avoid these common mistakes:
- Do not use hot water unless the care label specifically allows it.
- Do not wring swimsuits or rash guards. Press water out gently instead.
- Do not use fabric softener on performance or stretch fabrics.
- Do not dry swimsuits or rash guards on high heat.
- Do not use extra detergent to “really clean” them.
That last one gets people. Too much detergent can leave residue behind, especially in modern washers that use less water. Residue can make fabrics feel less fresh, trap odor, and irritate sensitive skin. Clean should rinse away. It should not move in and start paying utilities.

Keep Summer Gear Clean Without Making Laundry Weird
Summer gear asks a lot from your laundry routine. It brings home chlorine, salt, sunscreen, sand, sweat, and whatever was living at the bottom of the swim bag. The trick is to deal with it early, wash it gently, and avoid the habits that wear fabrics down faster than necessary.
Rinse swimsuits and rash guards soon after wearing them. Pretreat sunscreen stains before they settle in. Shake out sandy towels before they meet the washer, and skip fabric softener and high heat on stretchy fabrics.
When it’s time to wash, Charlie’s Soap makes it easy to keep summer gear ready for the next trip to the pool or beach. Explore the Charlie’s Soap laundry collection and build a simple routine that keeps swimsuits, rash guards, towels, and everything else ready for the next sunny day.
FAQs About Washing Summer Gear
Can I wash swimsuits in the washing machine?
Yes, many swimsuits can be machine washed if the care label allows it. Use cool water, a gentle cycle, a mesh laundry bag, and a small amount of detergent. Air drying is the safer choice for keeping elastic in better shape.
Should I wash swimsuits after every swim?
A quick rinse after every swim is smart, especially after chlorine or saltwater. You may not need a full wash every single time, but you should not let chlorine, salt, sunscreen, and sweat sit in the fabric for days.
Why does my swimsuit still smell like chlorine after washing?
Chlorine smell can linger if the suit was not rinsed soon after swimming or if detergent residue is trapping odor. Rinse it promptly and wash with a detergent designed to rinse clean.
Can I put rash guards in the dryer?
It is better to air-dry rash guards. Dryer heat can be hard on stretchy synthetic fabrics and may affect fit over time. Hang or lay flat to dry, away from high heat.
How do I keep beach towels from smelling musty?
Shake out sand, wash towels before they sit too long, avoid overloading the washer, and dry them completely before folding. If your towels still smell musty, hard water or detergent residue may be part of the problem.
Is fabric softener okay for beach towels?
Fabric softener can leave a coating that makes towels feel less absorbent over time. If towels are stiff or scratchy, look at detergent amount, washer load size, drying habits, and hard water before reaching for softener.
Can sunscreen permanently stain clothing?
Some sunscreen stains can become stubborn if they sit too long or go through high heat before being treated. Pretreat early, wash according to the care label, and check the stain before drying.
