You get home from a weekend camping trip, tired and happy, and stuff the tent into the back of the cupboard. It’s still damp from the morning dew, there’s mud on the groundsheet, and the bag is only half zipped because you couldn’t be bothered to fold it properly. Three months later you pull it out for your next trip and it smells like a gym locker, the fabric has mildew spots, and one of the pole sections has corroded. That tent cost you £300, and you’ve just knocked two years off its life because you were tired on a Sunday evening.

Why Proper Tent Storage Matters
A tent is one of the most expensive items in your camping kit. Mountaineering Scotland and other outdoor organisations stress that gear care extends equipment lifespan and reduces waste — and tents are the item where care makes the biggest difference. A decent family tent costs £200-500, and a quality backpacking tent costs £150-400. The fabric, waterproof coatings, and pole materials are all designed to withstand weather — but not neglect. Store your tent properly and it lasts 10-15 years. Store it carelessly and you’re buying a new one in three.
What Goes Wrong
Three things destroy stored tents: moisture, UV degradation, and compression damage.
- Moisture causes mould and mildew, which eat through waterproof coatings and leave permanent stains and smells
- UV exposure from storing near windows degrades nylon and polyester fibres, making them brittle
- Compression from being packed too tightly for too long breaks down the fabric’s waterproof membrane at fold lines — those white creases you see on old tents are where the coating has cracked
The 30-Minute Investment
Properly cleaning, drying, and storing a tent takes about 30 minutes after each trip. That’s 30 minutes that saves you £200-500 on a replacement. No other camping maintenance task has a better return on investment.
Cleaning Your Tent Before Storage
Never store a dirty tent. Mud, sap, bird droppings, and food residue attract mould and can permanently stain fabric if left for months.
Basic Cleaning
- Set up the tent in your garden or drape it over a washing line
- Shake out loose dirt, leaves, and debris from inside
- Wipe down the outer fly and inner tent with a damp cloth or sponge
- For mud: let it dry completely, then brush off with a soft brush. Dried mud comes off much easier than wet mud
- For sap or stubborn marks: use a specialist tent cleaner (Nikwax Tech Wash or Grangers Performance Wash, about £8-10 for a bottle that lasts years) or mild soap (not washing-up liquid — the detergents strip waterproof coatings)
What NOT to Use
- Washing-up liquid — strips DWR (durable water repellent) coatings
- Bleach — destroys fabric fibres and waterproof membranes
- Pressure washers — force water through seam tape and damage coatings
- Washing machines — the agitation destroys pole sleeves, seam tape, and waterproof coatings. Never machine wash a tent, regardless of what anyone on a camping forum tells you
The Groundsheet
The groundsheet takes the worst beating — mud, stones, moisture from below. Flip it over and scrub both sides with a damp cloth. Check for holes or tears while you’re at it. A small puncture repair (about £3 for a kit) now prevents a wet sleeping bag later.
Drying Your Tent Completely
This is the single most important step. A tent stored even slightly damp will develop mould within weeks. Mould doesn’t just smell bad — it permanently damages waterproof coatings and can’t be fully removed once established.
How to Dry a Tent
The ideal method: set it up in your garden on a dry, breezy day with the doors and vents open. Leave it for 4-6 hours, rotating it if the sun moves, until every surface — inner, outer, groundsheet, and guy lines — is completely dry. Pay particular attention to seams and corners where moisture collects.
No garden? Drape the tent over a banister, clothes horse, or door frames indoors. It takes longer (12-24 hours) but works. Open windows to improve airflow and prevent your house smelling like a canvas factory.
The “No Time to Dry” Scenario
Sometimes you pack up camp in the rain and drive straight home. That’s fine — just don’t leave the tent packed for more than 24-48 hours. Unpack it as soon as you can and dry it out. Many experienced campers dry their tent on Monday evening after a weekend trip. That brief window is safe. Leaving it packed and damp for a week is not.
Check Before Packing Away
Run your hand over the fabric. If anything feels cool or clammy, it’s not dry. Hold the fabric up to light — damp patches appear darker. The poles, especially aluminium shock-corded ones, also need to be dry. Water trapped inside pole sections causes corrosion over time.
How to Fold and Pack a Tent for Storage
Here’s where most people get it wrong: they stuff the tent back into its original bag. For trips, that’s fine — you’re unpacking it in a few hours. For storage, it’s the worst thing you can do.
Don’t Use the Stuff Sack for Storage
A stuff sack compresses the fabric tightly, creating permanent fold lines where the waterproof coating cracks over time. Those crisp white creases on old tents? That’s where the polyurethane coating has delaminated from repeated compression in the same spots.
The Better Method
- Loosely fold the tent into a rough rectangle — no need for precision
- Roll it loosely (not tightly) into a cylinder
- Place it in a large breathable bag — an old cotton pillowcase, a mesh laundry bag, or a large canvas tote. Some tent manufacturers (Hilleberg, Terra Nova) sell oversized storage bags for this purpose
- The key is loose and breathable. The fabric needs air circulation to prevent moisture buildup
Why Loose Storage Works
Loose storage means no permanent fold lines, no compression damage to the waterproof coating, and better air circulation. The tent takes up more space in storage, but the trade-off — a tent that stays waterproof for a decade instead of five years — is worth it.
Where to Store Your Tent
Ideal Conditions
- Cool — consistent temperature, ideally below 20°C
- Dry — low humidity, no risk of damp
- Dark — away from direct sunlight or UV-emitting light sources
- Ventilated — some airflow to prevent musty smells
Good Storage Locations
- Spare bedroom wardrobe — temperature-controlled, dry, dark
- Under-bed storage — if the tent is in a breathable bag, this works well
- Indoor cupboard — the airing cupboard is too warm; a standard cupboard is fine
Bad Storage Locations
- Garage — temperature swings from freezing to 30°C+ damage coatings. Rodents chew through tent fabric. Dampness is common in UK garages.
- Garden shed — same problems as garage, plus higher moisture levels
- Loft — extreme heat in summer (lofts regularly exceed 40°C in the UK) accelerates coating degradation. Temperature cycling between seasons is also harmful.
- Car boot — the worst option. Heat, UV through the rear window, and compression from other gear. Never leave a tent in the car longer than necessary.
The Compromise
If indoor storage isn’t possible, a garage or shed is better than nothing — but use a sealed plastic storage box (not airtight — drill a few small holes for ventilation) to protect from rodents and damp. Add a few silica gel packets to absorb residual moisture.
Dealing With Mould and Mildew
If you’ve already made the mistake and your tent smells musty or has visible mould spots, all is not lost — but act quickly.
Identifying the Problem
- Musty smell without visible marks — early stage mildew. Catch it now and the tent is salvageable.
- Black or green spots on the fabric — established mould. The spots are permanent stains, but you can kill the mould and prevent further damage.
- Fabric feels slimy or the coating is peeling — severe damage. The tent may still be usable but the waterproofing is compromised. This is the point where reproofing (or replacement) becomes necessary.
Treatment
- Set the tent up outdoors in direct sunlight — UV kills mould spores
- Mix a solution of 1 part white vinegar to 3 parts water in a spray bottle
- Spray affected areas generously and leave for 15-20 minutes
- Scrub gently with a soft brush or sponge
- Rinse thoroughly with clean water
- Dry completely — this is critical. Treating mould and then storing the tent damp just brings it back
- If mould persists, a specialist tent cleaner (Nikwax Tech Wash) in a bathtub soak is the next step. Follow the product instructions for dilution ratios
Prevention Is Everything
The Camping and Caravanning Club recommends drying your tent within 48 hours of packing it away as the single most effective mould prevention measure. Once mould establishes itself in the fabric weave, it’s extremely difficult to eliminate completely.
Storing Tent Poles and Pegs
Poles
Tent poles are usually aluminium alloy connected by elastic shock cord. Store them assembled (extended) if you have space — this reduces tension on the shock cord and extends its life. If space doesn’t allow, store them in their pole bag but don’t leave the sections tightly compressed. Over years, permanently compressed shock cord loses its elasticity, and poles start separating at the joints during setup.
Check pole sections for dents or bends before storage. A slightly bent section weakens the pole and increases the chance of it snapping under wind load. Replacement sections are available from most tent manufacturers for about £5-10 each.
Pegs
Rinse mud off pegs before storage — dried mud is corrosive to aluminium and steel pegs over time. Dry them and store in a separate peg bag. Count your pegs and compare against the tent’s requirements — losing a few pegs per trip is normal, and discovering you’re three pegs short when setting up in rain is miserable. Replace missing pegs before storing.
Steel pegs can rust if stored damp. A light spray of WD-40 prevents this, though it’s usually only necessary for steel pegs stored in damp conditions (garage, shed).
Reproofing Before or After Storage
When to Reproof
If water no longer beads on the outer fly and instead soaks in (known as “wetting out”), the DWR coating needs refreshing. You can test this at home: sprinkle water on the fly. If it beads up and rolls off, the coating is fine. If it soaks in and darkens the fabric, it’s time to reproof.
Reproof Before Storage
Reproofing before storage means the tent is ready to go when you next need it — no rushing to treat it the night before a trip. Apply Nikwax TX.Direct spray-on (about £10) to the outer fly while the tent is set up, or use the wash-in version in a bathtub soak. Follow the product instructions for drying — most spray-on treatments need heat activation (a hairdryer on low, or tumble dryer on low for treated clothing).
Similar to reproofing a waterproof jacket, the process is simple and takes about 30 minutes of active work plus drying time.
Reproof After Storage
If you’d rather reproof closer to your next trip, that’s fine too. Just make sure the tent is clean and dry before storage regardless. Reproofing a mouldy tent is pointless — the mould compromises the fabric structure that the coating bonds to.
Long-Term Storage Over Winter
If you’re a fair-weather camper who packs the tent away from October to March, long-term storage needs a bit more care.
Pre-Storage Checklist
- Clean — full wash with Nikwax Tech Wash or mild soap
- Dry — set up for a full day in dry weather, or drape indoors for 24+ hours
- Inspect — check for tears, broken zippers, damaged seam tape, missing pegs, worn guy lines
- Repair — patch any holes, replace damaged pegs or guy lines. Repairs are easier now than in a rush before your first trip
- Reproof — if the DWR is worn, treat it now
- Pack loosely — in a breathable bag, not the stuff sack
- Store indoors — spare room, under bed, or wardrobe. Not the garage, shed, or loft
Mid-Winter Check
If storing for 4+ months, it’s worth pulling the tent out mid-winter for a quick unfold and air. This prevents any residual moisture from causing problems and lets you confirm nothing has gone wrong. Five minutes of your time, once, protects months of stored gear.
Common Storage Mistakes That Ruin Tents
Storing Damp
Already covered, but it bears repeating: this is the number one tent killer. Even “a bit damp” is enough for mould to establish in weeks.
Using the Stuff Sack for Long-Term Storage
The stuff sack is for transport, not storage. Permanent compression damages waterproof coatings. Use a large breathable bag instead.
Leaving It in the Car
Cars get hot. The rear window lets UV through. The boot compresses the tent under other gear. A tent left in a car for a month in summer can suffer more coating damage than a year of careful storage.
Storing Near Chemicals
Garages and sheds often contain solvents, petrol, paint, and cleaning products. The fumes from these chemicals can degrade nylon and polyester fabric over time. If you must store in a garage, keep the tent well away from chemical storage.
Forgetting About Critters
Mice and rats love tent fabric for nesting material. If storing in a garage or shed, use a sealed container. Check for chew marks before your next trip — a mouse hole in your flysheet is an unpleasant discovery at midnight in the rain.
Never Inspecting Between Trips
A quality tent deserves a quick inspection before storage. Small tears become big tears over months. A zipper that’s slightly stuck now will seize completely by spring. Seam tape that’s peeling will lift further. Spend five minutes looking the tent over — it’s easier to fix things now than to discover them in a field.
Frequently Asked Questions
Can I store my tent in the garage? It’s not ideal. Garages have temperature swings, damp, and rodent risk — all harmful to tent fabric and coatings. If it’s your only option, store the tent in a sealed container with ventilation holes and silica gel packets, away from chemicals and direct sunlight.
How long can a tent stay packed wet? No more than 48 hours. Beyond that, mould begins to establish in the damp fabric. If you pack up camp in rain, unpack and dry the tent as soon as you get home — even draping it over furniture indoors overnight is better than leaving it in the bag.
Should I store tent poles assembled or disassembled? Assembled (extended) if you have the space. This reduces tension on the internal shock cord and extends its lifespan. If space is limited, storing in the pole bag is fine but avoid tight compression.
How do I get mould smell out of a tent? Set up the tent in direct sunlight, spray affected areas with a 1:3 white vinegar to water solution, scrub gently, rinse, and dry thoroughly. For persistent odour, soak the tent in Nikwax Tech Wash solution in a bathtub following product instructions. Prevention through proper drying before storage is far easier than treatment.
Do I need to reproof my tent every year? Not necessarily. Test the DWR by sprinkling water on the fly — if it beads and rolls off, the coating is still working. Most tents need reproofing every 2-3 years with regular use, or when you notice the fabric wetting out instead of repelling water.
