How Silica Gel and Moisture Absorbers Can Stop Your Kit Going Mouldy This Winter

When the damp British winter sets in, it’s not just your boots that suffer - your gear does too. Whether it’s a tent packed away after a weekend of rain or a box of kit tucked in the garage, trapped moisture can quickly lead to mould, odours, and ruined fabric. Luckily, there’s a simple, inexpensive way to fight back: silica gel and moisture absorbers.
What Are Silica Gel and Desiccants?
Silica gel and other desiccants are small packets filled with moisture-absorbing materials designed to keep things dry. You’ve probably seen them in new shoes or electronics boxes with the warning “Do not eat” printed on the front. Their job is to pull water vapour out of the air, protecting your kit from damp and mould growth.
These handy little packets are incredibly effective at keeping your stored equipment fresh, especially through the wetter months. Whether it’s your camping gear, tools, or outdoor clothing, a few well-placed desiccants can save you from unpleasant surprises when you unpack in spring.
Why Moisture Is a Real Threat to Your Gear
The UK’s cold, wet winters mean humidity levels stay high for months at a time. Even when stored indoors, condensation can build up inside plastic boxes and bags, creating the perfect conditions for mould and mildew. Once it takes hold, it can stain fabrics, damage coatings, and leave a smell that’s nearly impossible to remove.
At UKSN, we’ve learned that prevention is far easier than cure. That’s why we keep silica gel and moisture absorbers in our kit boxes, tent bags, and practically everywhere.
Top Tips to Keep Your Kit Mould-Free
Use Moisture Absorbers in All Storage Boxes
Pop a few silica gel packs into every sealed container or dry bag. Larger storage boxes or crates may need two or three to keep humidity under control.
Recharge or Replace Them Regularly
Many silica gel packs can be recharged by drying them in a low oven for about an hour. If they start to look clumpy or lose effectiveness, it’s time to replace them.
Always Store Gear Completely Dry
Even a trace of moisture can lead to mould. Make sure tents, sleeping bags, and tarps are bone dry before packing away - especially after wet or humid adventures.
Store in a Cool, Ventilated Space
Avoid leaving your gear directly on concrete floors or against outside walls. If possible, use shelves, insulated boxes, or moisture-resistant containers with a small amount of airflow.
Check Long-Term Storage Regularly
If your kit will be packed away for months, check it every so often. Early signs of condensation or musty smells are your cue to dry everything out and replace the desiccants.
Keep Some in Unexpected Places
Silica gel isn’t just for camping gear - drop a few into toolboxes, camera bags, and even your car boot to prevent foggy windows and corrosion.
Keep It Dry, Keep It Ready
Silica gel and other moisture absorbers might not look like much, but they’re a quiet hero of kit maintenance. They protect your investment, stop mould before it starts, and ensure your gear stays adventure-ready all year round.
Before you seal up your boxes for winter, take a minute to throw in a few desiccant packs - a small effort that could save you a lot of time, money, and frustration later.
