Can You Put Antifreeze in Screenwash?

There are few things as inconvenient (not to mention unsafe) as a frozen windshield in the relentless sweep of winter with its bone-chilling temperatures. Unfortunately, though, this is all too common in our harsh UK climate.

But can a solution used to keep your engine cool in the heat and warm in the cold be the answer to your screenwash woes? More specifically, can you put antifreeze in screenwash? The answer may surprise you, but yes - you can.

That being said, we don’t necessarily advise you to put antifreeze in screenwash on your own. You need the best screen wash with antifreeze that’s been engineered to precision to avoid risks and maximize benefits. And that’s exactly what you’ll find here at Jennychem.

Dive in as we demystify the world of antifreeze and screenwash, giving you the clarity you need for those frosty mornings on the road.

Can You Put Antifreeze in Screenwash?

So, can you put antifreeze in screenwash to keep your windscreen crystal clear despite harsh, frigid temperatures? You can - but it’s not as black and white as yes or no. So, let’s pull the curtain back further by looking at the chemistry behind the compounds.

The Chemistry Behind Antifreeze and Screenwash

Antifreeze, as its name suggests, is engineered to reduce the freezing point of the water-based fluid in a car's radiator, ensuring it remains liquid and circulates even in frigid temperatures. 

Key ingredients often include ethylene glycol or propylene glycol, combined with corrosion inhibitors and other additives. 

On the other hand, screenwash is a cocktail formulated primarily to clean and improve the glide of wipers across the windscreen - removing dust, grime, salt, and in some cases, ice.

While it may contain chemicals to reduce its freezing point, its primary components often revolve around detergents and solvents to tackle road grime, oils, and insect splatter.

Marrying these two without due care can result in an inefficient blend that neither cleans nor prevents freezing effectively. That being said, let’s look at some risks of combining antifreeze with screenwash below.

Potential Risks of DIY Combinations

Simply pouring antifreeze into your screenwash reservoir might seem like an easy hack, but it comes with several potential pitfalls:

  • Chemical Reactions: Antifreeze and screenwash are formulated for different tasks. Mixing them could lead to unexpected chemical reactions which might compromise their effectiveness or even produce hazardous substances.
  • System Damage: Your windshield washer system is not built to handle the viscous nature of pure antifreeze. Using an improper mixture could lead to clogs or damage to the pump and nozzles.
  • Streaking and Visibility Issues: Antifreeze isn't designed to be sprayed onto a windshield. Its residue might result in streaking, reducing visibility - a significant safety concern.
  • Corrosion Concerns: Some types of antifreeze can be corrosive when in contact with certain materials, potentially causing issues with the seals or components in the washer system.

The last thing you want to do is more harm than good and be left asking - why is my screen wash not working? This is the appeal of professionally designed solutions.

Benefits of Professionally Designed Solutions

There's a clear advantage in leveraging products that have been professionally formulated to handle both cleaning and frost prevention rather than venturing into uncertain DIY territory. These benefits include:

  • Optimal Performance: A dual-action product ensures your windshield is clean while also protecting the fluid from freezing.
  • Safety First: Products formulated by experts undergo rigorous testing to ensure they're safe for both the vehicle and the environment.
  • Cost-Effective: While it might seem economical to mix products at home, using a product designed for a specific purpose often results in more extended periods between refills, thus offering better value over time.
  • Protection: Premium mixtures often include added benefits, such as corrosion inhibitors, ensuring longevity for your washer system components.

In essence, while it's tempting to concoct your own screenwash and antifreeze blend, the potential risks can outweigh the perceived benefits. 

It's always advisable to invest in solutions crafted with both challenges in mind, ensuring the safety and functionality of your vehicle's systems.

That being said, does screenwash have antifreeze in it at Jennychem?
