Windscreen Washer Additive
Rain-X Windscreen Washer Additive helps maintain year round Rain-X treatment by instantly applying the Rain-X water beading technology every time it’s used.
Rain-X Windscreen Washer Additive is the ideal solution for a windscreen that has been pre-treated with Rain-X Rain Repellent, to ensure that this transparent, water repellent layer on the windscreen is maintained over time. The Rain-X Washer Additive applies rain repellent to the windscreen every time this is used, and will replenish any areas of the windscreen where the solution has worn off. This will ensure the water beading technology remains effective for the duration and will also clean the windscreen to a streak free shine.
- Cuts through bug residue, tree sap, bird droppings and road grime
- Re-applies Rain-X Rain Repellent each time windscreen washer fluid is used
- Provides streak-free cleaning to improve visibility and driving comfort
- Available in a 1 litre bottle
