A common question we are asked is: can you use dishwashing detergent in the windscreen wash system of your vehicle?

We highly recommend only using a dedicated windscreen cleaner for best visibility and to wash your windscreen regularly.

Dishwashing soap is made to remove grease and caked-on food, it’s good at this because it’s an abrasive soap. When you use an abrasive soap in the windscreen wash system of your vehicle the liquid damages the rubber valves and pump fittings and, over time, blocks the water jets.
