Rain-X is unaffected by normal screen washing. Abrasion by wiper blades and trapped grime will gradually reduce performance and durability. Depending on the amount of driving and how often the wiper blades are used, Rain-X can last from 2-3 weeks to several months before a new application is necessary.
Rain-X Rain Repellent can be applied to side and rear windows to help improve visibility all the way round.
Before application, ensure the screen is thoroughly cleaned. In particular, remove all waxes and silicones that may have been applied if the car has been through a car wash.
- Apply to a dry screen at temperatures above +5°C using a circular motion.
- Allow to dry and then thoroughly buff with a paper towel or lint free cloth until the glass screen is sparkling.
- Check the condition of the wiper blades. Deteriorating rubber or grime can cause smears/filming on the glass. Even new blades should be cleaned. Apply a good quality, glass cleaner to a clean cloth and wipe the rubber wiper blades until all grime is removed.
