How to Store Your Cool Box Over Winter and Prevent Mould

After a busy season of touring, your cool box has probably seen its fair share of picnics, groceries and holiday treats. Taking a little time to clean and store it properly before winter can prevent mould, lingering odours and unnecessary wear.

1. Empty and defrost the cool box

Remove all food, drinks and ice packs. If your cool box has an ice compartment or any frost build-up, allow it to defrost naturally with the lid open.

2. Clean the interior thoroughly

Food spills and condensation are the main causes of mould and smells.

  • Wipe the interior with warm water and a mild, food-safe detergent.
  • Pay special attention to corners, seams and drain points.
  • Rinse with clean water and dry with a soft cloth.

3. Don’t forget the seals and lid

Rubber door seals can trap moisture and crumbs.

  • Gently clean seals with a damp cloth and mild detergent.
  • Check for damage or splits that could affect the seal next season.

4. Freshen with a gentle deodoriser if needed

If any odour remains, avoid harsh chemicals that could taint food later.

  • Place an open tub of bicarbonate of soda inside the cool box for a few days.
  • Alternatively, use a dedicated fridge deodoriser.

5. Store with the lid slightly open

Sealing a cool box completely can trap moisture inside.

  • Prop the lid open slightly using a folded cloth or purpose-made spacer.
  • Ensure children and pets cannot climb inside while it is stored.

6. Protect the exterior

Wipe down the outside of the cool box and check handles, hinges and catches.

  • Tighten any loose screws if accessible.
  • Store in a dry, shaded area away from direct sunlight or heat sources.

Ready for next season

These simple care steps help keep your Mestic cool box clean, hygienic and ready for the next adventure. When spring returns, you’ll be able to plug in, cool down and load up without any unpleasant surprises.
