Time for a trip to the auto store! The short answer is no, you can’t put Windex in your washer fluid reservoir. Here’s why:
  • Ammonia is often found in Windex products and can leave your windshield streaky or with a glare. It could also ruin your glass’s tint!
  • Windex contains chemicals that can be damaging to more than one part of your vehicle including the washing system and your car’s paint job.
  • Windshield washer fluid is formulated to resist freezing in the cold, while Windex is not and may freeze in your fluid reservoir, causing another set of problems.
So all in all, it’s not a good idea to replace your windshield washer fluid with Windex and it will save you money in the long run to buy some proper washer fluid at the auto store. And if you’re looking to save money on your car insurance while you’re at it, the Jerry app is a good place to start.
