17 Proven Hammock Cleaning Questions Answered 2026

Top Questions About Hammock Cleaning

I've spent the last eight years testing and washing dozens of backyard and camping hammocks. From cotton rope to coated nylon, I've seen every stain. Here are the most common hammock cleaning questions I get from readers, answered with real-world methods.

Common Hammock Cleaning Questions

Can I put my cotton rope hammock in the washing machine?

I'll be honest, tossing a heavy cotton rope hammock into a standard washing machine is a massive gamble. The thick ropes can easily unweave, tangle, or even damage your machine's internal agitator. If you have a modern front-loader without an agitator, you can try a delicate cycle with cold water. But in my experience cleaning outdoor gear for years, hand-washing it in a plastic kiddie pool with a cup of mild detergent like Woolite yields much better results. You avoid the fraying and keep the ropes intact.

How do I clean mildew off a Sunbrella fabric hammock?

Sunbrella fabric is incredibly durable, but it still traps mildew if left damp in the shade. I mix one cup of bleach, a quarter cup of mild soap like Dawn, and a gallon of water. Spray it directly on the black spots and let it sit for exactly 15 minutes. Scrub lightly with a soft-bristle brush, then rinse thoroughly with a garden hose. The fabric won't fade if you stick to this exact ratio.

What's the best way to remove tree sap from nylon?

Tree sap is a nightmare for camping hammocks. I've tested rubbing alcohol, and it works wonders on coated nylon without stripping the waterproofing. Just dab a microfiber cloth in 70% isopropyl alcohol and gently rub the sap until it dissolves. Don't scrub too hard, or you'll damage the DWR (Durable Water Repellent) coating.

How often should I wash my outdoor hammock?

It really depends on your environment. If you live under oak trees or have kids who track mud everywhere, a quick rinse every two weeks is necessary. For standard backyard use, I recommend a deep clean twice a season—once in May and again in September. This prevents pollen and bird droppings from setting into the fibers permanently.

Can I use bleach on a colored polyester hammock?

Don't do it. Chlorine bleach will instantly strip the dye from colored polyester, leaving you with a blotchy, faded mess. Instead, I use OxiClean Versatile Stain Remover. Dissolve one scoop in a gallon of warm water (around 90°F) and soak the hammock for 30 minutes. It lifts the stains while keeping the colors vibrant.

How do I clean the metal carabiners and spreader bars?

Hardware needs love too, especially if you live near the coast. Salt air corrodes aluminum carabiners fast. I wipe mine down with a damp cloth and a drop of 3-IN-ONE oil every month. For wooden spreader bars, a quick sanding with 220-grit sandpaper followed by a coat of teak oil keeps them from splintering and rotting.

Is it safe to pressure wash a hammock?

Absolutely not. I made this mistake once with a Kärcher K1700 on a low setting, and it shredded the cotton weave instantly. The concentrated PSI is just too aggressive for woven fabrics. Stick to a standard garden hose with a spray nozzle set to the "shower" or "flat" setting for a safe, effective rinse.

How do I get bird poop off my hammock quickly?

Speed is everything here. If you let it bake in the sun, it bonds to the fibers. I keep a bottle of Folex Instant Carpet Spot Remover in my patio cabinet. Spray it on the fresh droppings, wait two minutes, and wipe it away with a damp paper towel. It works flawlessly on both canvas and nylon.

What water temperature is best for washing parachute nylon?

Parachute nylon (like the stuff used in ENO hammocks) melts or warps under high heat. Always use cold or lukewarm water, ideally below 85°F. Hot water compromises the structural integrity of the ripstop weave. I wash mine in a bathtub with a tablespoon of Nikwax Tech Wash to preserve the fabric's breathability.

How do I dry a thick cotton hammock without it getting musty?

Cotton holds a massive amount of water, and laying it flat guarantees a mildew smell. After squeezing out the excess water, I hang it fully extended on a clothesline in direct sunlight. Flip it every two hours. If it's humid outside, I point a Vornado oscillating fan directly at the thickest knots to speed up the 24-hour drying process.

Can I use dish soap on a waterproof camping hammock?

Standard dish soaps like Dawn are designed to strip grease, which means they'll also strip your hammock's factory waterproofing. I only use specialized cleaners like Gear Aid Revivex Pro Cleaner. This isn't the cheapest option at $15-25 a bottle, but it cleans the dirt without ruining the DWR finish. You'll save money in the long run by not having to re-waterproof it constantly.

How do I remove sunscreen stains from white fabric?

Sunscreen contains avobenzone, which reacts with iron in hard water to create stubborn orange rust stains. I've found that applying a paste of baking soda and white vinegar directly to the stain breaks down the oils. Let it fizz for 10 minutes, scrub with an old toothbrush, and rinse with cold water.

How do I clean a Mayan hammock without tangling the strings?

Mayan hammocks are notorious for turning into a giant bird's nest in the wash. I tightly bind the end loops together with a heavy-duty rubber band or zip tie before submerging it. Wash it gently by hand in a tub with cool water and a splash of baby shampoo. Never put a Mayan hammock in a washing machine, no matter what the tag says.

What's the best way to wash a hammock with a built-in pillow?

Built-in pillows usually contain poly-fill that clumps when soaked. I spot-clean the pillow area with a damp sponge and upholstery cleaner. For the rest of the hammock body, I submerge it in a tub while keeping the pillow propped up on the edge. If the whole thing must be washed, throw three clean tennis balls in the dryer on low heat to break up the clumps.

How do I remove rust stains from the fabric near the carabiners?

Rust transfers easily from cheap steel hardware to fabric. I squeeze fresh lemon juice directly onto the orange spots and sprinkle a little table salt over it. Let it sit in direct sunlight for an hour. The UV rays activate the acid, lifting the rust right out of the weave.

Expert Tips for Hammock Maintenance

• Reapply DWR Annually: Waterproof camping hammocks lose their factory coating after a season of heavy use. I spray mine with Gear Aid Revivex Durable Water Repellent every spring. Hang the dry hammock outside, spray an even coat from 8 inches away, and let it cure for 24 hours before packing it away.
• Use a Hammock Sock: When your landlord inspects next week or you just need to clear the patio, don't just bunch the hammock up. I use a dedicated nylon stuff sack (often called a hammock sock) to store it. This keeps spiders out and prevents the suspension straps from tangling with the fabric.
• Inspect the Suspension Webbing: The fabric might be clean, but the straps hold your weight. I check my tree straps for micro-tears and UV degradation every time I wash the hammock. If the webbing feels stiff or looks faded, replace it immediately. A $20 strap failure will ruin your afternoon.
• Wash the Carabiners Separately: Never wash your metal hardware in the same bucket as your fabric. Grit and sand trapped in the carabiner gate will scratch the anodized aluminum. I wash my carabiners in a separate bowl of warm soapy water, dry them completely, and lubricate the gate with a dry graphite powder.

Frequently Asked Questions

Can I dry clean my hammock?

I strongly advise against dry cleaning. The harsh chemical solvents used in the process will degrade the synthetic fibers and strip any waterproof coatings. Stick to gentle hand-washing or a delicate machine cycle with mild detergent to preserve the fabric's lifespan.

How do I get rid of a lingering smoke smell?

Campfire smoke clings to nylon and cotton like glue. I fill a spray bottle with equal parts white vinegar and water, then mist the entire hammock. Hang it outside in a breezy spot for two days. The vinegar smell dissipates completely, taking the smoke odor with it.

Is it safe to wash a hammock with a built-in mosquito net?

You can wash it, but you must protect the netting. Mosquito net mesh tears easily on zippers or agitators. I turn the hammock inside out and place it in a large mesh laundry bag before washing. Use a gentle cycle and absolutely no fabric softener, which clogs the tiny mesh holes.
