The British winter can be unforgiving, and if you’ve invested in a high-quality heated gilet, it has likely become your best friend during those crisp morning commutes or weekend treks in the Highlands. However, after weeks of battling the elements, your gear might be looking—and smelling—a bit less than fresh.
The big question that haunts every owner is: "Can I actually wash this without ruining the electronics?"
The short answer is yes. Modern heated apparel is designed with durability in mind, using waterproof-coated carbon fibre heating elements. However, you cannot simply toss it in with your tea towels and hope for the best. To protect your investment, follow this definitive guide to laundering your heated gear safely.
The Pre-Wash Checklist: Safety First
Before you even think about water, you must prepare the garment. Think of this as "decommissioning" your tech.

- Disconnect and Remove the Battery: This is the most vital step. Open the internal battery pocket, unplug the power bank, and remove it entirely. Never submerge a lithium-ion battery in water.
- Check the Pockets: Ensure your keys, phone, or any loose change are removed.
- Secure the Cables: Take the connector cable and tuck it neatly back into its designated pocket.
- Zip Everything Up: Close the battery pocket zip and the main front zip. This prevents the metal "teeth" of the zips from snagging the internal heating mesh or the outer fabric during the wash programme.
Choosing Your Method: Machine vs. Hand Wash
Whilst hand washing is the gentlest approach, most modern heated gilets (like those from reputable brands) are perfectly safe for a washing machine, provided you follow these specific parameters.
Option 1: The Machine Wash (Recommended for Convenience)

- Use a Mesh Laundry Bag: This is a "pro-tip" for longevity. Placing your jacket inside a large mesh bag prevents the wires from being pulled or twisted too aggressively by the machine's agitator.
- Select the Right Programme: Set your machine to a 'Delicate' or 'Hand Wash' cycle.
- Temperature Matters: Use Cold Water (no higher than 30°C). High temperatures can damage the waterproof seals protecting the internal circuitry.
- Detergent Choice: Use a mild, non-biological detergent. Crucially, avoid fabric conditioners and bleach.
Option 2: Hand Washing (The Ultra-Safe Route)
If you are particularly nervous or have a very lightweight heated base layer, hand washing in a clean basin or bathtub is best. Use lukewarm water and gently knead the fabric. Do not wring or twist the jacket. Wringing is the leading cause of "dead zones" in heated apparel, as it can snap the delicate carbon fibre filaments inside.
The Drying Process: Heat is the Enemy
It might seem ironic, but the one thing a heated jacket hates is external heat. Avoid these common mistakes:
- NO Tumble Drying: The intense, tumbling heat of a dryer can melt the insulation surrounding the wires and shrink the fabric.
- NO Wringing: As mentioned, avoid the temptation to twist the water out. Instead, lay the jacket flat on a clean towel and roll it up gently to absorb excess moisture.
- NO Ironing: An iron will make short work of ruining your heating pads.
The Correct Way: Hang the jacket on a sturdy hanger or lay it flat on a drying rack. Allow it to air dry in a well-ventilated spot away from direct sunlight or radiators.

Expert Tip: Ensure the battery connector plug is 100% dry before you attempt to plug the battery back in. Even a tiny amount of residual moisture can cause a short circuit.
Maintenance & Off-Season Storage
To ensure your gilet lasts for many winters to come, keep these maintenance tips in mind:
- Spot Cleaning: If you’ve only got a bit of mud on the cuff, don’t wash the whole garment. Use a damp cloth and a bit of mild soap to spot-clean the area.
- Summer Storage: When the sun finally returns, don’t just bundle your jacket into a tight space. Hang it up to keep the heating elements flat.
-
Battery Health: Lithium batteries dislike being empty for long periods. Charge your battery to about 50% every three months during the summer to maintain its lifespan.
Conclusion: Stay Warm, Stay Smart
Washing your heated vest doesn't have to be a nerve-wracking experience. By treating it as a piece of "wearable technology" rather than just a standard coat, you ensure that the carbon fibre elements stay intact and the heat continues to flow.
