With the weather getting colder, it’s easy to forget that some items don’t hold up well to low temperatures. CarMoney’s automotive experts have revealed the things drivers should never leave in their car overnight in winter, including medication.
Carbonated drinks can burst
A frozen soft drink will expand as it freezes and put pressure on the dissolved CO2 inside, causing the can to explode or fizz further when manually opened.
Andrew Marshall, Marketing Manager at CarMoney, said: “Just as some items can be damaged by high temperatures if left in our cars, many unexpected items can also be negatively affected by the cold.
“Not only can it potentially cost us money due to broken items, but it can also impact our health, such as medications and even dangerous explosions of certain products.
“To combat this, we recommend that you always take key car items into the house where it’s warmer and safer.”

Musical instruments may be subject to damage
Musical instruments should always be taken indoors to avoid inadvertent damage during a cold snap.
Violins, guitars, and cellos, and other wooden instruments are vulnerable to shrinking and expanding in cold weather, which will damage or break the glue joints, rendering them out of tune at best or unplayable at worst.
Spare batteries can explode and leak in cold weather
Batteries will drain sooner due to cold temperature affecting electrochemical reactions inside the battery, and alkaline batteries may even burst and leak.

Laptops and cell phones may have compromised internal batteries
Similar to why leaving batteries in the car over the winter is a bad idea, laptops and other electronics will fare just as badly due to their internal lithium-ion batteries being compromised by the cold.
Expensive electronics should also be removed from the car overnight for safety reasons.
Aerosols destabilize at extremely cold temperatures
Aerosols can become hazardous when exposed to extreme cold. A low temperature can cause destabilization of pressurized canisters, leading to cracks or even an explosion of the canister. The same goes for hairspray, spray paint, or WD-40.
Medications may become ineffective at low temperatures
Many people may leave their daily medications in the car as a reminder to take them on their daily commute, but leaving prescribed medications in the car overnight during the winter can impair their effectiveness and even make them unsafe to take. .
Pills and hard capsules should be the least affected, but active chemicals in liquids and injectable medications can be affected by low temperature and can degrade quickly.
Drivers should therefore always store their medications at room temperature to maintain their effectiveness.
