No, it is not recommended to put dish soap in your windshield washer fluid reservoir. Dish soap is not formulated for use in automotive systems and can cause various issues. Here's why you should avoid using dish soap in your washer fluid:
Foam and Bubbles: Dish soap produces a significant amount of foam and bubbles when mixed with water. If you add it to your washer fluid, the excessive foam can clog the washer fluid lines, pumps, and nozzles, preventing proper spraying and distribution of the fluid onto the windshield.
Residue and Streaks: Dish soaps may leave behind a residue when used in washer fluid. This residue can impair visibility and cause streaks on the windshield, making it difficult to see clearly while driving.
Corrosion and Damage: Dish soaps may contain chemicals that can be corrosive to certain automotive components, such as rubber seals, plastic parts, and the washer fluid system itself. Prolonged use of dish soap in your washer fluid can lead to deterioration, leaks, and damage to these parts.
To ensure proper functioning and maintenance of your vehicle's washer fluid system, it is advisable to use windshield washer fluid specifically designed for automotive use. Windshield washer fluids are formulated to provide effective cleaning, streak-free performance, and compatibility with the components of your vehicle's washer system.
If you encounter a situation where you're out of windshield washer fluid and need a temporary solution, it's better to use plain water instead of dish soap. While water alone may not provide the same cleaning power as washer fluid, it can still help clear away some dirt or grime from the windshield until you can refill with the appropriate washer fluid.
