Washer additives sound like just another expense to be added to the bill of car ownership.
However, these formulas frequently come in handy.
If all you’ve ever put in your washer reservoir is water, you’re missing out on the cleaning power of washer additives.
What do washer additives do?
Washer additives are sold as concentrates to be diluted in water.
They are formulated to help cut through grease, traffic film, bugs and other environmental contaminants.
Yes, when sprayed with enough water, these contaminants can be rinsed from your windscreen.
But with washer additives in the mix, you’ll find your wipers have an easier time clearing that muck.
Especially when your windscreen is hit with bird poop. Water just doesn’t cut it.
Additives can cut right through to restore visual clarity.
How much should I add to my car’s washer reservoir?
This really depends on the product and the size of your reservoir.
Follow the directions on the label. You may need to top up the rest of your reservoir with water after filling it with additive.
Are these products expensive?
They are relatively inexpensive, especially if you are not brand-conscious.
Shops like Autobacs will have plenty of options for motorists to choose from.
Will additives harm my glass or wiper blades?
Not to our knowledge.
These products are formulated to help you clean your glass, not eat into it.
It is unlikely that they will harm your car or its paintwork.
That said, unless you’re a master chemist, do not mix anything else into the product.
Follow the instructions and you should be enjoying cleaner windscreens between washes.
What if my windscreen is badly contaminated, like in the photo above?
It would be best to give your car a thorough washing instead of relying on washer fluid alone!
