Can I Put Windex In My Vehicles Washer Fluid Reservoir?

If you’re anything like me, you’ve probably wondered, “Can I put Windex in my car’s washer fluid reservoir?” The definitive answer is no. There are a lot of reasons why you shouldn’t put Windex in your washer fluid reservoir, despite the fact that it may seem like a convenient and economical solution.

Windex includes compounds that may cause damage to your vehicle. Not only may it damage the car’s washing system, but it can also ruin the paint finish. In addition, Windex is not designed to resist freezing in cold weather, but windshield washer fluid is. If Windex is left in the reservoir, it may freeze and cause additional complications.

In the long run, it will cost you more to replace your windshield washer fluid with Windex. Windex may appear to be an inexpensive and simple remedy, but it is not worth the risk. Instead, visit an auto parts store to acquire the right washer fluid. It may cost more initially, but it is the safest and most prudent choice.
