All-season washer fluid of fairly good quality removes insects, dirt, salt and even light snow and frost from the windshield. The unique Rain-X technology creates a water-repellent film similar to the "Anti-Rain" effect, which improves visibility behind the wheel in any weather - even in heavy rain drops will roll off the glass without leaving streaks. The liquid does not freeze at temperatures down to -1°F, so it can be used almost all year round. This volume is enough for about a season with daily driving and not heavy washing of the glass. In general, it is an ideal solution for comfortable and safe driving both on city streets and highways.
