As the colder weather approaches your locks could be put at risk. Door locks, window locks, car locks and garage locks are all at risk of freezing when exposed to lower temperatures for long durations.

Cold air can lead to your home locks filling with an icy layer, thereby blocking the key slit making entry a challenge. Locks can also suffer contraction due to icy temperatures and cold air, making your key no longer compatible with the lock and you being able to reopen it.


Therefore, it is vital to keep your locks clean during the winter months in order to ensure you’re never locked out of your home due to lower temperatures.

How to Keep Your Door Locks Clean:

  1. Avoid Using Hot Water

Although pouring hot water over a lock may seem like the go-to solution, you are putting metallic door locks, latches, handles and hinges at risk of being damaged. There are plenty of other cleaning methods (see below) that can unfreeze your locks without causing damage.

  1. Pewter Door Locks

Add a teaspoon of salt and flour with a cup of vinegar until it forms a paste. Rub the paste against your pewter lock and allow it to sit for 15-60 minutes and clean off with warm water. This will leave your pewter door looking clean and functioning properly.

  1. Unlacquered Brass and Real Copper Door Handles

Combine a tablespoon on flour, vinegar and salt into a bowl and continue to mix until if forms a paste. Then, rub it into your brass or copper lock and wait a few minutes and wipe away with warm water. Once rinsed, find a soft cloth to dry your lock and use a thin layer of car wax to prevent rust.

  1. Say no to Petroleum-based Cleaning Products

Petroleum based products are prone to attracting and sticking to grime and dirt. Therefore, you should instead use spray graphite or a Teflon product for an easy way to keep your door locks clean.

  1. Unfreeze Door Locks with Hand Sanitizer

As well as being a superb germ killer, the chemistry between ethanol and isopropanol is also great at lowering the freezing point of water. This method only takes up to 30 seconds to free your keyhole and locking mechanism from ice through melting.

Wait for the process to complete before trying your key. If it doesn’t work first time do not force your key, just simply wait a little longer.
