Pitch & PackQuick answer
To remove odors from a tent, start by airing it out in sunlight, then clean with a mild soap solution or enzyme cleaner for organic smells. For mildew, use a vinegar or specialized tent cleaner. Always dry completely before storage to prevent future odors.

A tent that smells of mildew, campfire smoke, or stale air can make a night outdoors less enjoyable. Odors often build up from moisture, body oils, and improper storage. The good news is that most smells can be eliminated with simple cleaning and airing techniques. In this guide, we’ll walk you through how to remove odors from a tent, from quick fresh-air fixes to deep cleaning with enzyme cleaners and vinegar. For stubborn mildew smells, you may also need to check out our guide on how to remove mold from tent fabric.
Identify the Odor Source
Before you start cleaning, pinpoint what you’re dealing with. A musty, earthy smell usually points to mildew or mold from storing the tent damp. A sour, body-odor-like scent comes from sweat and skin oils. Smoke smells cling to fabric after campfires, while food odors can attract pests. Identifying the source helps you choose the right cleaning method. For example, mildew needs a disinfecting approach, while smoke may require an enzyme cleaner. If you see visible mold spots, stop and read our guide on how to remove mold from tent fabric before proceeding, as that requires a more targeted treatment.
Air Out Your Tent
Often, the simplest solution is the most effective. Set up your tent in a dry, breezy spot out of direct sunlight for a few hours. UV rays can degrade fabric over time, so a shaded area with good airflow is ideal. If the weather cooperates, leave it up overnight. Fresh air helps dissipate volatile compounds that cause smells. For mild odors, this alone may be enough. Flip the tent inside out to air both sides, and unzip all doors and vents. If the tent is damp, make sure it’s completely dry before packing, as any residual moisture will restart the odor cycle.
Wash with Mild Soap
When airing isn’t enough, a gentle hand wash is the next step. Use a bathtub or large basin filled with cool or lukewarm water and a cleaner specifically made for tents, or a very mild, non-detergent soap. Avoid laundry detergents, fabric softeners, and bleach, which can strip waterproof coatings. Submerge the tent and gently agitate, paying extra attention to areas that touch skin, like the floor and sleeping area. Rinse thoroughly with clean water until no suds remain. To preserve your tent’s waterproofing, always use a cleaner that won’t leave residue, and consider reapplying DWR after washing.
Use Vinegar or Baking Soda
For organic smells like sweat or mildew, natural deodorizers work well. Mix one part white vinegar with four parts water and spray or sponge it onto the affected areas. Let it sit for 15–20 minutes, then rinse. Vinegar neutralizes odors and has mild antimicrobial properties. Alternatively, sprinkle baking soda over the floor and let it absorb smells overnight, then vacuum or shake it out. Both methods are safe for most tent fabrics, but try in an inconspicuous spot first. Be aware that harsh cleaners can strip waterproof coatings; if you need to reapply, see our guide on how to waterproof a tent.
Enzyme Cleaners for Tough Smells
When smells persist after washing, an enzyme cleaner can break down the proteins and oils causing the odor. These cleaners are especially effective on body oils, pet accidents, and food spills. Look for a product labeled safe for synthetic fabrics and follow the manufacturer’s instructions. Typically, you’ll spray or soak the area, let it sit for the recommended time, then rinse. Enzyme cleaners work best when the tent is warm and damp, so do this on a mild day. After treatment, rinse thoroughly and dry completely. This step often rescues a tent that seems permanently funky.
Dry and Store Properly
The best defense against odors is proper drying and storage. Never pack a tent away damp, even for a few hours. After cleaning or a rainy trip, hang it or set it up indoors with a fan until every seam and corner is bone dry. Store the tent loosely in a breathable cotton sack or large mesh bag, not compressed in its stuff sack, which can trap moisture. Keep it in a cool, dry place away from direct sunlight.

Frequently asked questions
Can I use bleach to remove tent odors?
No, bleach is too harsh for tent fabrics and can damage waterproof coatings, weaken seams, and discolor materials. Instead, use a mild soap, vinegar solution, or an enzyme cleaner designed for outdoor gear. If you must disinfect, a diluted hydrogen peroxide solution is safer, but always try on a small hidden area first.
How do I get campfire smoke smell out of a tent?
Airing out is the first step. Set the tent up in a well-ventilated area, ideally in sunlight, for several hours. If the smell persists, hand wash with a mixture of warm water and mild soap, then rinse thoroughly. For stubborn smoke, an enzyme cleaner or a vinegar soak can break down the particles. Always dry completely before packing.
Will washing my tent damage the waterproof coating?
It can, especially if you use harsh detergents or scrub aggressively. Always use a cleaner specifically formulated for tents or a very mild, non-detergent soap. After cleaning, you may need to reapply a DWR coating to restore water repellency. For more on that, check our guide on how to make a tent more waterproof.
How often should I clean my tent?
A deep clean once or twice a season is usually enough, but spot-clean spills and dirt after each trip. If you camp frequently in humid or dusty conditions, you may need to clean more often. The key is to never store a damp or dirty tent, as that’s the fastest route to mildew and odors.
Can I put my tent in the washing machine?
No, a washing machine can stretch, tear, or delaminate tent fabrics and damage the mesh. Even front-loaders without agitators are risky. Always hand wash your tent in a bathtub or large basin using cool water and a gentle cleaner. Rinse well and air dry.
Bottom line
A fresh-smelling tent makes every trip more pleasant. By airing it out, cleaning gently, and drying completely before storage, you can keep odors at bay for years. Regular care not only eliminates smells but also extends the life of your shelter. For more ways to improve your camping experience, see our guide on how to make a tent more comfortable.
