Car dehumidifiers have their uses in the colder parts of the year. Alongside winter driving kits, they're a fab way to keep your car safe during the harsher months. When a modern car is in use, we have the air conditioning on to quell moisture build-up. But when we have the car sitting idle or sitting idle in the car waiting for the takeaways to be ready, what then?
This is where dehumidifiers step in. They're great because they absorb moisture from the air. When the air is dry, mould or mildew growth is inhibited and so too are the musty smells that come along with them. We've recommended a small selection of the best car dehumidifiers to use when a car is idle or in storage.

What to consider with car dehumidifiers
Dehumidifiers dry the air and help avoid moisture-related problems in the first place. Meanwhile, air fresheners mask a smell but some don't eliminate the cause. They're usually something that even a rechargeable torch can't reveal. So really, if your car is plagued with bad smells, you'll be better off finding the root of the problem. Once you've done that, a dehumidifier is a lovely way to keep the cabin of your car fresh. They're especially useful when going into the winter months when condensation and misty windows come out to play.
The best solution to permanently avoid smells permeating throughout a car is to keep the interior clean. It's also recommended to air it out on a nice day as well. However, the outside of your car can be impossible to keep clear, which is where the best de-icers come flying in.
But the issue can lie in the air conditioning system too. Mainly because car air-con can also be subject to mould and bacteria growth. An air conditioning evaporator takes moisture from the air and it normally drains what it collects through a hose. But that tube can suffer from a blockage. This can result in moisture pooling in the evaporator, causing mould or mildew problems inside the air-con system. STP's Air-Con Cleaner is the answer to that issue. Imagine the product as a million hard-working snow shovels clearing away all the bacteria. Generally speaking though, it's worth keeping in mind that such systems can get dirty too.
