Nothing can ruin a camping trip faster than waking up in a damp, musty tent. Having your tent wet is not just uncomfortable – it can lead to mold and mildew, which pose health hazards. Plus, excess moisture buildup can damage your tent’s fabric over time.

That’s why learning how to properly air out a tent is a crucial skill for any camper. Taking the time to dry out your tent after each trip will extend its lifespan and prevent nasty surprises on your next adventure.

Why Airing Out Your Tent is Crucial

The Dangers of a Wet Tent

As mentioned, a persistently wet tent creates an ideal environment for the development of mold and mildew.

Exposure to mold spores can cause everything from headaches and congestion to chronic lung illnesses in those with compromised immune systems. And mildewis also no joke – simply touching a mildewy tent surface can give you a rash.

A moisture buildup inside your tent can also lead to:

  • Unpleasant musty odors

  • Deterioration of waterproof coatings

  • Warping or weakening of poles and fabric

By airing out a tent regularly, you allow moisture to fully evaporate so mold and mildew cannot take hold. This keeps every component of your shelter in peak condition.

The Importance of Tent Care

Buying a tent is a significant investment for avid campers, who often time spend thousands of dollars in a tent with all the specs needed for their trips.

So it doesn’t come as a surprise that with proper maintenance and care, a high-quality tent can serve you on many more camping trips and adventures. But remember: the tricky part is knowing how to take care of your tent.

Here are some tips:

  • Air out your tent after every trip, even short overnighters

  • Check for rips and re-coat with seam sealer if needed

  • Wash the tent body every season

  • Keep it stored loosely when not in use

  • Avoid direct sun exposure when packed

  • Check expiration dates on tent stakes, poles, etc.

Following this basic tent care checklist will add years to your shelter’s lifespan. Don’t wait until it’s too late – some time spent on maintenance as soon as you purchase your tent can save you from unnecessary replacements down the road.

Types of Tents and Their Materials

Let’s go through popular tent materials so you can make the most informed maintenance decisions.

Canvas vs. Synthetic Tents

When it comes to tent material, there are two main options:


  • Made of natural, breathable cotton canvas

  • Heavy duty and extremely durable

  • Can withstand harsh weather well

  • Prone to shrinkage when wet

  • Heavier, making portability harder


  • Usually made of polyester or nylon

  • Coated with waterproofing treatments

  • Lighter weight and more portable

  • Provides less airflow than canvas

As you can see, canvas and synthetic tents both have pros and cons. You may want to go synthetic for backpacking trips and reserve heftier canvas tents for car camping.

Tent Coatings and Waterproofing

To keep you dry in the rain, most new tents come with a durable water repellent (DWR) coating.

This chemical treatment causes water to bead up and roll off the tent surface rather than seeping through. However, DWR coatings degrade over time with sun exposure and abrasion.

You’ll know it’s time to re-coat your tent when you notice:

  • Water soaking into fabric instead of beading up

  • Dark, wet spots left after rainfall

  • Fabric feeling stiff and lifeless

Look for tents with quality, long-lasting DWR formulas. A good DWR coating should last at least a few seasons with proper care. Don’t forget to reapply seam sealing regularly.

How to Air Out a Tent: Step-by-Step Guide

Always let your tent dry completely before packing it away

Now that you know why airing out your tent is so important, let’s get into how to do it right.

Setting Up the Tent for Airing

  • Choose a warm, dry, sunny day to air out your tent

  • Find a flat spot of ground without sticks or rocks nearby

  • Layout the tent footprint if your tent has one

  • Assemble the tent poles and stake corners

  • Try your best to get the tent in full tent set up position

This allows all fabric surfaces to be exposed to fresh air and sunlight. Think of it as a practice pitch to keep your tent set up skills sharp before your next camping trip!

Cleaning and Drying the Tent Floor and Fabric

We’ve written in the past about how to clean & wash tents, so here is the summary:

  • Sweep out debris from the tent floor with a broom or brush

  • Mix a mild soap with warm water

  • Dip a soft non-abrasive sponge in the solution and gently scrub the floor and walls/ceiling to remove dirt and stains from the tent’s fabric

  • Use a dust pan to remove any leaves, grass, etc.

  • Rinse everything thoroughly with clean water

  • Allow the tent to dry completely before packing it up

Give special attention to any visibly soiled spots on your tent walls or doors. Cleaning the tent regularly will also help remove foul odors.

Airing Out the Tent Indoors vs. Outdoors

Ideally, you should air out your tent outdoors on a dry, sunny day. But if hearsh weather forces you inside:

  • Set up the tent in a basement, garage or large room

  • Place fans around the tent to improve airflow

  • Leave tent doors open as much as possible

  • Allow longer dry time since you’re using a less ventilated area

Before taking down an indoor tent, inspect it closely and ensure it’s completely dry. Even a little moisture left inside can cause mildew.

Tips for Quick Drying

If you need to dry out your tent in a hurry before packing it up, this is for you:

Using the Rain Fly and Tent Doors

  • Drape the rain fly off to the side to prevent blocked airflow

  • Fully open all tent doors and roll up door flaps

  • Position the tent to catch prevailing winds

  • Use a towel to absorb any morning dew

This allows for maximum air circulation and acceleration of the drying process. Within a few hours, your tent should be ready for storage or transport.

However, our recommendation is to always go for the full & not rushed drying process.

The Role of Air Circulation

The key to fast tent drying is promoting ample air flow.

Avoid drying tents in:

  • Shaded areas with no direct sunlight

  • Low-lying grounds with poor drainage

  • Areas with heavy rain or high humidity

Instead, try drying on:

  • Windy hilltops and ridges

  • Gravel or sand substrates that won’t hold standing water

  • Slanted tarps propped up on a slope

Also, turning the tent every so often helps all sides dry evenly.

Tent Repair and Maintenance

No tent stays in perfect condition forever – repairs and upkeep are inevitable. Make sure you have these supplies for maintenance and fixes:

Basic Tent Repair Kit Essentials

Seam Sealing and Duct Tape

Two versatile items that deserve special mention are seam sealer and duct tape, as they have multiple of uses for tent repairs and maintenance:

Seam sealer

  • Re-seal leaking seam tape

  • Patch holes

  • Improve waterproofing

  • Works even in cold weather

Duct tape

  • Make emergency pole splints

  • Fix rips and tears temporarily

  • Patch holes in rain fly

  • Seal tent stitching

  • Repair broken poles

Duct tape and seam sealer will get you out of a jam when full tent repairs aren’t feasible. They are must-haves for every camper’s repair kit. Neglect them at your own risk.


Heading out for a fun camping adventure? Don’t forget to air out your tent after each trip, even if short, to prevent moisture build up.

Quick recap of what to do:

  • Start by fully setting up your canvas tent or new tent and wiping down the clean surface of the floor to remove any tree sap or debris

  • Use a mild detergent and warm water to scrub the walls and ceiling to eliminate odors and refresh the waterproof coating

  • Always allow the tent to completely air dry before packing it into the tent bag to avoid funky smells and mold

  • Pay extra attention to drying out canvas tents, as their heavy fabric takes longer to dry out

  • If your tent needs more permanent repairs, use cold water sealant to fix rips and re-seal seams

  • Quick drying sessions remove moisture build up, extending the life of your tent and its coating

  • Finally, store your completely dry tent loosely rather than cramming it into a small sack

With this basic care, your shelter will be ready for many future camping trips and adventures.

Bon voyage on your next fun outdoor adventure!

Frequently Asked Questions
