Gear Maintenance Between Seasons: Keep Your Kit Ready Year-Round

Why Maintenance Matters

UK conditions are hard on gear. Rain, mud, salt air, peat bogs, and the particular humidity of a British summer — none of it is kind to technical fabrics, coatings, or metal components. The average tent, sleeping bag and waterproof jacket that gets cleaned and maintained properly will last eight to ten years. The same gear neglected will often start failing meaningfully within three.

The economics are straightforward. A bottle of Nikwax TX.Direct costs around £10. A replacement waterproof jacket costs £130 to £400. Maintenance is not optional, it is the cheapest upgrade your kit will ever get.

Tent Care: Clean, Dry, Inspect

A tent packed away damp after a UK trip — which is almost every UK trip — will develop mould on the inner mesh and degrade the flysheet coating faster than almost anything else you can do to it.

After every trip:

• Set the tent up as soon as you get home and allow it to dry completely, including the inner, groundsheet and all pockets
• Brush loose mud off poles and tent fabric before it dries and becomes abrasive
• Wipe the flysheet with a damp sponge and cool water — avoid machine washing, which degrades seam tape and DWR coatings

Between seasons:

• Check pole sections for hairline cracks or bent joints — a failed pole mid-trip is a miserable repair in the rain
• Run a finger along seam tape on the flysheet and groundsheet; any lifting tape should be re-sealed with a product like McNett Seam Grip (around £6)
• Inspect zipper teeth for distortion and lubricate with a dry wax zipper lubricant — Nikwax Tent and Gear SolarProof (~£12) also refreshes UV protection on the flysheet
• Store the tent loosely in its bag in a dry, dark location — never compressed in the stuff sack long-term, and never in a damp garage or loft where temperature swings accelerate elastic degradation in pole bungee cord

Sleeping Bag Care: Washing and Loft Recovery

The most expensive mistake people make with sleeping bags is either never washing them (oils from skin and hair gradually destroy down clusters and synthetic fibres), or washing them incorrectly.

Down sleeping bags:

• Wash in a front-loading machine on a gentle 30°C cycle — never a top-loader with an agitator, which destroys baffles and tears fill fabric
• Use Nikwax Down Wash Direct (~£6) or Grangers Down Wash, not standard detergent which strips natural oils from down
• Tumble dry on low heat with two or three clean tennis balls — the balls break up clumps as down dries and restore loft
• Run two or three drying cycles; down retains moisture long after it feels dry to the touch, and a bag packed away with damp fill develops mould inside the baffles

Synthetic sleeping bags:

• Follow the same front-loader, gentle cycle process using Nikwax Tech Wash (~£8)
• Tumble dry faster and at a slightly higher temperature than down
• Synthetic fill does not recover loft as reliably as down after repeated washing — if a bag has lost significant warmth and washing does not restore it, the fill is degraded

Storage: Never store a sleeping bag compressed in its stuff sack between seasons. The sustained compression permanently crushes fill clusters and synthetic fibres, reducing loft and thermal performance. Store loosely in the large cotton storage sack that quality bags ship with, or in a king-size pillowcase.

Waterproof Clothing: Reproofing Before It Fails

The DWR (Durable Water Repellent) coating on a waterproof jacket or trousers is the first line of defence — when it fails, water soaks into the outer fabric face, the jacket feels cold and heavy, and the breathable membrane becomes much less effective. Most people reproof too late.

Signs the DWR needs refreshing:

• Water stops beading and instead wets out across the fabric surface
• The jacket feels noticeably heavier in rain
• You feel clammy inside a jacket that is technically still waterproof

Process:

1. Wash the garment in Nikwax Tech Wash or Grangers Performance Wash — contamination from skin oils, sunscreen and dirt suppresses DWR and must be removed first
2. While still damp, apply Nikwax TX.Direct Wash-In (~£10) or Grangers Performance Repel Plus in another wash cycle
3. Tumble dry on low heat or iron on a low setting through a cloth — heat reactivates the DWR and is not optional

Check seam tape at the same time. Run a damp cloth inside the jacket at the shoulders and underarms — any water penetration through seam lines indicates tape has lifted and needs resealing with McNett Seam Sealer.

Boot Care: Cleaning, Conditioning and Sole Inspection

Boots take more punishment per trip than any other item of gear. UK terrain — peat, heather, scrambling rock, boggy ground — tests waterproofing and leather regularly.

After every trip:

• Remove insoles and dry them separately; damp insoles held against the boot lining prevent the boot from drying properly and accelerate mould
• Brush mud off while still slightly damp — dried mud is harder to remove and more abrasive
• Stuff boots with newspaper to absorb moisture and hold the shape while drying; never dry near direct heat which cracks leather and warps synthetic components

Between seasons:

• Clean leather boots with Nikwax Leather Footwear Cleaning Gel (£6), then condition and reproof with Nikwax Waterproofing Wax for Leather (£8) or Grangers G-Wax (~£7), which maintains waterproofing and leather suppleness
• For synthetic/fabric boots, use Nikwax Fabric and Leather Proof (~£8) spray-on application
• Check the midsole for compression: press firmly with a thumb — significant compression without springback indicates the cushioning has degraded and replacement or new insoles are needed
• Inspect the outsole for worn lugs, particularly on the heel and toe. Significant lug wear on technical terrain is a genuine grip and safety issue
• Replace insoles every one to two seasons if you cover significant mileage — Superfeet Green (~£40) are a cost-effective upgrade that extend boot comfort considerably

Stove Maintenance: Seals, Jets and Fuel Lines

Stove failures in the field range from inconvenient to dangerous. A pre-season check takes ten minutes.

Canister stoves:

• Check the valve mechanism seats correctly when a canister is attached — any resistance or gas smell without ignition suggests a damaged valve
• Clean the burner jet with the jet-cleaning tool included with most stoves; a blocked jet produces a weak, yellow flame
• Inspect the O-ring at the canister connection point — any cracking, distortion or flattening means replacement before use (O-rings cost pennies from most outdoor retailers)

Liquid fuel stoves (MSR WhisperLite, Dragonfly):

• Inspect the fuel line along its full length for cracks, brittleness or stiffness indicating degradation
• Clean the generator and pump mechanism per the manufacturer's maintenance guide — MSR publish clear teardown guides online
• Replace pump cup leather annually if used regularly; a degraded pump cup causes inconsistent pressure and unpredictable flame behaviour
• MSR Maintenance Kit (~£15) covers most field repairs and is worth keeping in your kit bag

Store fuel canisters upright in a cool, dry space away from heat sources. Do not store partially-used canisters for more than a season without checking valve integrity.

The Between-Seasons Checklist

Run through this after each season before putting gear into storage:

Good gear maintained properly does not degrade in a straight line — it holds its performance for years, then falls off quickly at the end. Maintenance keeps you on the flat part of that curve. It also means you pick up problems before they become field failures: a seam tape issue found at home is a ten-minute fix; the same issue discovered in a storm on the Brecon Beacons is a wet miserable night.

Products mentioned — Nikwax, Grangers, McNett — are all available from outdoor retailers across the UK including Cotswold Outdoor, Ellis Brigham, and online from the manufacturers directly. None are expensive relative to the gear they protect.
