The Dirty Truth About Car Washes

Your car might look clean, but the environment pays the price.

🚗 A Clean Car with a Dirty Secret

There’s something satisfying about a freshly washed car.
Shiny paint. Gleaming windows. Smug neighbours.

But here’s what many people don’t realise:

How you wash your car matters just as much as how often.

That sparkling finish might be hiding a messy environmental footprint — one made of chemicals, microplastics, and polluted runoff.

Let’s get sudsy with the facts.

🧼 Two Main Types of Car Washes

  1. DIY Driveway Washes

  2. Commercial Car Washes (Automatic or Hand Wash)

Both get your car clean — but only one usually protects the environment.

🏡 The Problem with Driveway Washing

When you wash your car on a drive, you’re usually:

  • Using excess water (often 100–150 litres per wash)

  • Rinsing detergents, oils, brake dust, and microplastics straight into storm drains

  • Letting it flow untreated into rivers and streams

Think you’re just washing your car?
You're also polluting waterways and harming aquatic life.

🚿 Are Commercial Car Washes Better?

Yes — if they’re properly regulated.

  • Most use water recycling systems

  • They filter out pollutants before water enters the sewer

  • They often use biodegradable detergents

  • Some even run on solar power and use minimal water

In many cases, going to the car wash is less harmful than doing it yourself.

🌍 Tips for an Eco-Friendly Car Wash

✅ Skip the driveway wash unless you’re using eco-detergents and water capture
✅ Use a waterless car wash product (great for light cleaning)
✅ Choose commercial car washes with water recycling systems
✅ Use a bucket and cloth rather than a hose or jet wash
✅ Only wash when necessary — rain is free!

Hose at home100–150 litres❌ No🌍 High
Bucket + sponge~40 litres❌ No🌍 Medium
Commercial wash~40–70 litres✅ Yes🌿 Lower
Waterless wash~1 litre✅ Yes (in wipe)🍃 Lowest

Final Thought

Your car doesn’t care how you wash it.
But the rivers, fish, and frogs really, really do.

If you’re going to clean your car, do it consciously.
Because “clean” shouldn’t come with an environmental mess.

Caffeine With a Conscience: Sustainable Coffee at Home

  Caffeine With a Conscience: Sustainable Coffee at Home ( How to keep your brew strong but your footprint light ) For many of us, coffee is less a drink and more a survival mechanism. But behind every comforting cup is an industry that comes with a hefty environmental and social cost. From deforestation to exploitative labour , the true price of coffee can be far higher than what you pay at the till. The good news? You don’t have to give it up. You just need to drink it smarter. The Hidden Cost of Coffee Coffee production is linked to deforestation, water waste , and pesticide use . Global demand encourages intensive farming that depletes soils and biodiversity . Billions of single-use cups and pods end up in landfill every year. Your morning pick-me-up doesn’t have to be part of the problem. Choose Better Beans Look for certifications that mean something: Fairtrade : Farmers get a fairer deal. Rainforest Alliance : Supports biodiversity and sustainab...

  Using Ecosia: The Search Engine That Plants Trees ( Click. Search. Plant. Repeat. ) Imagine if every time you googled something, you planted a tree. No, it’s not some kind of green-tech fantasy — it’s Ecosia , a real search engine that uses its ad revenue to fund global reforestation projects. And all it takes is changing your browser’s homepage. What Is Ecosia? Ecosia is a free, privacy-respecting search engine based in Germany. It works just like Google or Bing, but with a twist: They use 100% of their profits to plant trees.

How It Works Every time you search on Ecosia, the platform earns revenue from clicks on sponsored search results (just like Google). Roughly 45 searches = 1 tree . The money goes to vetted reforestation projects with a focus on: Native bi...
