The cold season is hard work for a car. Not only do parts such as batteries need extra care, but slush, mud and ice are all waiting to clog up your windscreen.
That's why we all use screenwash. The challenge lies in using one that clears a windscreen without smearing any residual mud or insects across it. Wonder no more and see CAR's recommended screenwash products below.
Having windscreen wipers in sound condition is important too.
Concentrated or ready mixed?
There isn't much difference between the performance of each option. Both will do exactly the same job. The difference is that a concentrated screenwash will require you to add water to dilute it and a ready-mixed one will not.
This means that a concentrated one is better value but isn't the best for topping up on the go unless you have a reliable water supply. On the other hand, ready-mixed screenwash take up more space. It really comes down to preference but we suggest going for concentrated.
What to look for in a good screenwash
When choosing a screenwash, your top priority should be temperature. In the winter months, you'll be needing a screenwash that can cope with the colder temperatures. Some can work at -20 degrees if you live somewhere where it gets really cold.
If possible, find a screenwash that contains Bitrex. This additive is the most bitter tasting thing imaginable and will make anything unpalatable and almost impossible to swallow should a child or animal try and drink some.
Regarding scent, there is no difference in cleaning ability between a citrus-scented screenwash or a berry one. The only difference will be to your nose and the colour of the fluid.
The best screenwash
Editor's pick
Description
A small bottle of highly concentrated screenwash is what we like because it's good value, it takes up little space on the garage shelf, and diluting takes very little time out of your day to achieve. This 500ml of concentrate makes eight litres of screenwash (1:16 dilution) and remains liquid down to -45 degrees C. Does it clear without a smear? Yes it does. The downside is that it doesn't contain Bitrex so use common sense and don't store it in your child's bedroom.
Pros:
Good value
Concentrated
Biodegradable
Cons:
Totally Essential Screenwash is even more concentrated
A bit more eco
Description
We're not talking radically eco but somewhat improved. Totally Essential's formula is biodegradable and doesn't contain toxic methanol or ethylene glycol. The container is made from recycled plastic too. But Totally Essential Screenwash remains very effective. This is even more concentrated than the Autoglym screenwash and can make up to 20 litres of screenwash. It cleans well in a streak-free way. To help battle residue build-up, it also contains rain repellent. Also contains Bitrex.
Pros:
Biodegradable
Contains rain repellent
Five-litre volume also available
Cons:
A bit more expensive than Autoglym Ultimate Screenwash. but goes further
Best screenwash tablets
Description
Tablets are an easy way to mix a screenwash concentrate with water, and the 303 tablets are the best. Each tablet makes one gallon (about 4.5 litres) on screenwash. The 303 tablets are also non-toxic, biodegradable, very effective, and cut down on plastic packaging.
Pros:
Simple to mix
Biodegradable
Small packaging
Cons:
Only choice is 4.5 litres of mix at a time
Best value
Description
This solution is highly concentrated, with a dilution ratio of 1:9 in winter and 1:19 in summer. Therefore five litres will last you so long it may even see you out. Though unable to match Autoglym's -45, the Prestone screenwash will still work down to -23 degrees C. While it's the 'budget' option here it's still very effective.
Pros:
Great value
Big five-litre bottle
Cons:
Not biodegradable
Useful accessories:
Description
Screenwash bottles are designed to make pouring easier but accidents can happen. A simple funnel like this will make topping up your screenwash a doddle.
Description
You might wish to consider a glass cleaner too. We've tested this stuff and it's great, not least because it comes in a volume about twice that of most competition.
Best glass cloth
Description
Microfibre cloths are infinitely useful objects when it comes to cars. This one from Kent Car Care will prevent streaks and reduce drying time, perfect for when you've just washed your car's windscreen.
