Best Windshield Washer Fluids in the UK

If you're after premium products for your four-wheeled friend, the Glimmermann Extreme Winter Fluid Screen Wash may catch your fancy. Glimmermann Products is a very respectable family-run company that supplies a professional range of automotive products both at trade and at retail levels, so if you believe that your vehicle deserves the best care and don't mind spending extra money for it, look no further than this car wash.

What makes it so special is its effectiveness and dilution rate. Actually, for the summer season, you'll need to mix just 50 ml with 1 litre of water to get a highly-effective windscreen solution. It'll tackle grease, dirt and insect residue with ease, leaving nothing but sparklingly clean finish. And seeing that the bottle includes as many as 20 litres of fluid, we bet it'll last you for a year or two. Also, this makes it ideal for car services and families with multiple cars.

When it comes to cooler months, it works down to -20°C. For the highest protection during the most freezing of days, it should be used neat, while -16°C requires 1:2 proportion and -12°C requires 1:4 proportion correspondingly, which is still a great ratio for washer fluids.

With the great longevity like this and smear-free results, the Glimmermann Extreme Winter is worth every penny. It'll do the job brilliantly all year long, keeping your windscreen extra clean and your safety on the road extra high.

For those who're looking for a perfect alternative to "standard" car washers sold at petrol stations and supermarket, we've included the Krafft Methanol-Free Windscreen Washer Fluid onto our shortlist. Just as the name suggests, it's a high-quality windscreen cleaner that is free of methanol. It's based on organic tenso-actives and alcohols that deliver the same great cleaning results without affecting rubber and leaving any spots or streaks. The fluid deftly removes dirt, traffic film, insect stains, bird droppings and other build-ups from a car's windscreen, providing a driver with a crystal-clear view all year round. That is to say, despite being claimed to be suitable for up to -5ºC, the  product is non-freezing up to -9º, which makes it good for use almost all year round, especially considering the UK climate, which is very mild.

What we also like about the Krafft Windscreen cleaner is that it's a ready-to-use solution that doesn't need to be mixed with water, preventing you from the messes and saving your time on the diluting process. One bottle includes 5 litres of fluid, which should be more than enough to get most car tanks full.

Another benefit is that this washer delivers a water-repelling effect and, accordingly, prevents droplets from sticking on the windscreen. The rain drops just run off and let you see the road better, which is especially crucial when you're driving at high speeds. This also means that you have better vision and reduce the use of the wiper blades, thus, extending their service life. A win-win choice on all levels.

For those who get irritated by having large part-bottles of wash fluids all around, the SONAX company has come up with the solution - the 250-ml tub of ultra-concentrated wash/car cleaning agent. A little bottle like this is far easier to store in the trunk of a small car or under the sink compared to bulky containers that never seem to match the actual tank size of your vehicle.

Although the SONAX screen wash seems too expensive for the capacity, the high initial cost is easily offset by the amazing dilution ratio. Just 25 ml give 2.5 litres of cleaning fluid, which totals 25 litres for the bottle, making it a pretty decent value. Actually, it works out cheaper than 'ready to use' solutions sold at petrol stations and easily outperforms them when it comes to the cleaning power.

Once diluted, the SONAX wash delivers a clear vision in seconds. Utilising nanotechnology, it's super effective at lifting bug splats and removing road grime from the windscreen. It also instantly eradicates dazzling and greasy films, making the glass cleaner with no smear marks left behind. The water just beads off, while the screen wiper rubbers don't squeak or judder. That's largely achieved owing to the addition of the glycerine that keeps rubber supple.

All things considered, if you're tight on storage space (or just want to stay neat) but still looking for a high-performance washer, we can't recommend this super-concentrated mix highly enough.

Do you often find yourself driving in the rain and want to improve your safety on the road during those muddy days? Then this Washer Additive by Rain-X can become a real lifesaver in all senses of the word. It's a unique product with water-repellent properties that should be put into a washer reservoir each time the windscreen fluid is used. By doing so, you'll make your screen clearer than ever before and drastically improve its hydrophobic coating. This means you get not only a potent bug, dirt, tree sap, and grime fighter but also a water-repeller that will make raindrops to bead up and run off your windscreen. As a result, you won't need to use your wipers as often, thus improving your visibility on the road.

Just like most washers, the Rain-X needs diluting. In general, a 500-ml bottle will make up 4.5 litres of the mix for summer. For winter, it'll make up to 2 litres (2 parts water to 1 part of this additive will work for mild temperatures up to -5°C, while 1-to-1 part will be sufficient for freezing -10°C).

Overall, this Washer Additive by Rain-X is a good choice for rainy spring and autumn, as well as for those cold winter days when the frost starts 'biting' your nose. It'll do a great job of topping up and adding some water repellence to your car's windscreen, working amazingly well for rainy and snowy conditions. The water beads will easily spray off the screen, thus, significantly reducing the use of windscreen wipers.

Often experience problems with your washer jets working inappropriately or not working at all? Or, probably, the headlamp washer of your car has stopped to retract fully? Then, this BMW genuine windscreen cleaner can become a real lifesaver. The thing is that the fluid is suitable for use with fan nozzles, and if there is some sort of build-up inside them, just a couple of squirts with this cleaning solution will fix the problem.

Speaking about its main job, the BMW highly-concentrated washer has a great smell and cleaning power. It works wonders removing dirt, dead bugs, pollen, car wax residue, and dangerous greasy films that might impair the view through the windscreen or, even worse, cause dangerous glare from sunlight or headlights. It leaves the windscreen ultra-smooth and free from any smears. The solution is also very light, so it doesn't stick all over the vehicle after use.

As mentioned, it's a highly-concentrated cleaning additive with a mixing ratio of 1:100. Therefore, you'll be able to make 5 litres of windscreen washer fluid from a 50-ml bottle of concentrate, giving you the same value as other bargain washer fluids. The only exception is that this genuine BMW fluid cleans so immaculately that you may want to touch the window to make sure there is glass in front of you.

All in all, just any car owner who believes that their vehicle deserves the best should try the BMW windscreen cleaner. It's very effective and lasts a while. Plus, the tiny bottle like this can be easily stored in the glove compartment, just in case you run out of the washer on the road.
