Setup, Compatibility & Care
To use the Rain-X Windscreen Washer Additive, locate your vehicle's windscreen washer fluid reservoir—usually identified by a cap with a windshield icon. Ensure the engine is cool before opening. Pour the required amount of concentrate directly into the reservoir, then fill the remainder with clean water.
Compatibility is generally universal across all vehicle makes and models. For care, keep the bottle tightly sealed in a cool, dry place away from direct sunlight to maintain the integrity of the chemical formula. Do not mix this product with other concentrated additives unless specified by the manufacturer, as this may alter the cleaning efficiency or cause clouding.
