Tesco Concentrated Screen Wash (& Tesco Ready To Use) Decades of car maintenance know-how have gone into Prestone Extreme Performance Screen Wash, so you can be assured of outstanding performance with every spray. And with year-round cleaning guaranteed, you can use the same screen wash through all four seasons – for maximum cleaning performance and convenience. Screen wash reservoir caps are almost always blue, which should make it easy to find under the bonnet. Depending on the size of the bottle, we’d recommend using a funnel to add the screen wash. If you don’t have one to hand, turning larger bottles on their side can help with pouring.

Simply add enough screen wash to the reservoir so it meets the ‘max’ line, and then use your car’s wiper function (normally an arm switch on the steering wheel) to apply it to the front and rear windows. There’s no cheaper way we could find of making screenwash than this, except maybe putting a squirt of Fairy Liquid in the reservoir.

This is the same Prestone screen wash you’re used to, but now in a super-concentrated formula. Tough on dirt, streaks and grime, it’ll make light work of whatever winter sends your way.
