Drivers across the UK are being warned about the risk of leaving certain everyday items in their cars. As temperatures across the nation are rising, with a mini heatwave expected next week, experts are informing drivers of the “devastating damage” that can come as a result of leaving specific items in the vehicles, revealing that repair costs could set people back thousands.
Five common items identified by experts as risks when exposed to heat, potentially causing explosions, fire, or mould. From soft drinks to smartphones, things that might seem like “harmless clutter” can actually become hazardous. The car valuation experts at BigWantsYourCar.com emphasised that these risks come with warmer weather, especially if cars are left parked in direct sunlight.
One of them said: “Heat doesn’t just affect the engine or tyres – it can turn your car’s interior into an oven. Everyday items like deodorant cans, fizzy drinks or vapes can explode under pressure, causing serious damage to upholstery and electrics.”
Smoke and fire damage could cost motorists an average £1,764, while mould and stains as a result of leakages or spoiled foods can drive the repairs costs even higher. Additionally, research has found that mould-related repairs average to £1,250.
However, the repairs could stretch to a whopping £4,000 according to the experts.
“Many drivers are surprised to learn that something as simple as a can of cola or a damp towel can lead to significant damage. It’s especially common during heatwaves when people leave items in the car after a day at the beach, gym or park,” they added.
Five items drivers should not leave in cars:
- Carbonated drinks, as they can explode and cause stubborn stains
- Aerosol cans (deodorant, hairspray). They are highly pressured and prone to bursting in extreme heat.
- Vapes and gas lighters are fire hazards when left in hot, enclosed spaces.
- Smartphones and electronics have a risk of short-circuiting or battery damage.
- Food, wet towels, or gym clothes can quickly lead to mould growth and unpleasant smells.
The experts also emphasised that interior damage from heat-exposed items are not usually covered by insurance, as they are “typically seen as avoidable” and therefore car owners are left to sort out the repair bills themselves.
Drivers are advised to clean their cars after every trip, “especially during warm weather,” as taking prevention steps is easier and cheaper than spending money on repairs.
