Can Windshield Washer Fluid Be Mixed?
2 Answers
Windshield washer fluid can be mixed with water, but purified water should be used. Tap water contains many impurities that can adhere to rubber hoses and affect normal spraying. Here is more information about windshield washer fluid usage: 1. Effects: Long-term use may increase friction between the glass surface and the wiper, causing scratches on the glass. 2. Performance: Anti-fog performance: Forms a single-molecule protective layer on the glass surface; Anti-static performance: Eliminates static charges on the glass surface; Lubrication performance: Reduces friction between the wiper and the glass, preventing scratches; Anti-corrosion performance: Has no corrosive effect on any metal.
Having driven for over a decade, I've experimented with mixing windshield washer fluids a few times. During summer emergencies, I once mixed it with regular tap water, only to have the spray nozzles clog up shortly after—cleaning them was a real hassle. If you mix fluids with different freezing points in winter, crystallization clogging the lines is the least of your worries; the real danger is the reservoir cracking from freezing. Different brands' cleaning agents can react with each other, leading to scaling and rust buildup in the lines. Now, I stick to the blue -25°C rated washer fluid year-round for peace of mind. Honestly, a jug costs just tens of yuan—way cheaper than auto repairs. Never cut corners by mixing fluids.
