Is commercial screenwash better than water and home-brewed alternatives?

The short answer? Yes. Absolutely. It can be tempting to settle for plain water in your windscreen washer system or to attempt to make your own with household detergent or alcohol but whilst you will make cost savings in the short term and its effects are kinder to the environment, the risks involved to your vehicle in the long term just aren't worth the short term savings. Here are the top reasons you should be sticking the screenwash in your system:

Cleaning Power

When it comes to getting rid of traffic film, grease and insect residue, screenwash has plain water beaten hands down. The alcohol and detergent in screenwash cuts through dirt quickly and effectively, getting rid of visibility obstructions which plain water could end up smearing across the glass. Home-brews with alcohol or household detergent, washing up liquid for example, would help to remove the dirt but depending on the substance used, it could leave residue behind on the glass or cause damage to rubber and paintwork.
