Wipers – 101

Have you ever been driving in the torrential rain and struggled to see the road in front of you?  

Heavy rainfall is inevitable during these winter months, with reduced stopping distances now is the most important time to ensure your windscreen clearing systems are functioning correctly.

Considering this I’ve put together a KAAR-education list to help you see clearly through winter.

Maintain your washer fluid

Make sure there’s fluid in your washer reservoir. To find your washer fill point, open the bonnet and locate the washer fluid reservoir cap, which is normally blue and features a washer icon on top. Just top it up with fresh water if necessary. If yiu have your vehicle serviced with us we have already added a “Wurth” product during servicing.

If using an additive, don’t mix different solution types as they might not be compatible with one other and could lead to blockages further down the line. Read the instructions on the bottle to ensure you use the correct concentration; otherwise the liquid can become too foamy.

Do not add any household products to the washer fluid as they will cause the wiper rubbers to prematurely fail.


If your wipers smear in both directions, you may have worn or dirty blades, a dirty windscreen, or even contaminated/poor washer fluid.

If your blades are less than six months old, they may just need a clean with a cloth dipped in hot soapy water. You can even rub the blade with some isopropyl alcohol afterwards to remove any residue.

If the smearing is only in one direction, the blades could be too hard or perhaps even the wrong size. Either way, the wipers require replacement. There are many poor quality blades available, so if you are going directly to an automotive parts store consider this in your decision.


The sound of wipers screeching or chattering away is bad enough, but this can also lead to smearing on the windscreen itself.

Once again, this can be attributed to a dirty windscreen or wiper blades, but it could also be a result of a bent wiper arm reducing the blade tension or angle, essentially preventing it from working correctly.
