No, it is not recommended to put dish soap or any household cleaning products in your car washer fluid reservoir. Dish soap is not formulated for use in car washers and may cause damage to the system or even harm your car's paint and finish.
Car washer fluid is specifically designed to clean windshields effectively without causing any harm to the car's surfaces. It contains ingredients to help dissolve bugs, dirt, and other debris commonly found on windshields. Additionally, some car washer fluids also have antifreeze properties to prevent freezing in cold weather.
Using dish soap in your car washer fluid could lead to several issues:
Damage to paint and finish: Dish soap may contain harsh chemicals that can strip off the wax and protective coatings on your car's paint, leading to fading or damage over time.
Clogging of washer nozzles: Dish soap may not dissolve properly in the washer fluid reservoir and can clog the washer nozzles, causing improper spraying or even blockages.
Foaming and residue: Dish soap tends to foam a lot, and excessive foam in the washer fluid system can interfere with the proper functioning of the washer pump and wipers.
Potential system damage: The car's washer fluid system is designed to handle specific types of fluid, and using dish soap may cause damage to the pump, hoses, or other components.
For proper windshield cleaning and maintenance, always use a washer fluid specifically designed for automotive use. These fluids are readily available at automotive stores and gas stations. If you are in a situation where you're out of car washer fluid, using plain water temporarily is a better option than resorting to dish soap. However, for optimal performance and safety, it's best to use the appropriate washer fluid for your car.
