The cheap car cleaning mistake that could cost you thousands

It might seem like a cheap and easy way to clean your car, but one everyday kitchen staple could quietly cause serious damage to your paint – and cost you thousands to put right.

As the UK weather warms up, you’re bound to head outside to give your car a much-needed clean after months of winter grime. From road salt to mud and grit, your car takes a beating during colder months – making a proper wash essential.

But while it may be tempting to reach for a cheap household alternative to proper car shampoo, experts are warning that one common kitchen item could do more harm than good: washing up liquid.

Costing less than £1 in most shops, it might seem like a budget-friendly solution. However, regularly using it on your car could end up causing damage worth over £3,000, according to founder of car finance company ChooseMyCar.com, Nick Zapolski.

Here’s why you shouldn’t use washing up liquid to clean your car and some alternatives to consider.

Why washing up liquid is bad for your car

During the colder months, your car collects a mix of salt, sand, mud and slush – all of which can lead to rust and corrosion if not properly cleaned. While tackling this build-up is important, using the wrong product can make things worse.

Washing up liquid may appear to deliver good results the first time you use it, but it contains harsh, high-pH detergents and degreasers designed to break down oils and foot fats on dishes and cutlery. On your car, these harsh chemicals can gradually strip away protective layers of paint.

Over time, this can lead to:

• Fading and dull paintwork
• Cracks in the surface
• Risk of scratches
• Increased risk of rust and corrosion
• Residue and spots

And once the damage sets in, repair costs can quickly add up.

The true cost of a cheap shortcut

While minor fixes to paintwork might cost between £150 and £300, according to car insurance agency Start Rescue, Zapolski argues that more extensive damage can exceed £3,000. That’s particularly if areas such as wheel arches, sills or the boot floor become affected by rust.

Zapolski warns that drivers trying to save money could end up paying far more in the long run. “Millions of drivers may take advantage of the spring season and tackle cleaning jobs that may have been neglected during winter. But, while many may, understandably, search for cheap cleaning alternatives, the wrong item could lead to car damage and hefty costs.”

What should you use instead

Instead of using household products to clean your car, we’d recommend using a specialist car shampoo. These typically start at around £5 and are specifically designed to remove dirt and grime on cars without damaging paintwork.

We’ve actually compiled a list of the best car shampoos you can currently buy to help restore your car’s paintwork to a glossy, like-new finish below.

If you’re wanting a more thorough clean, professional car washes – which usually ranges between £15 for a basic wash and £110 for a full valet, according to trades site Checkatrade – can restore your vehicle safely without risking costly repairs.

Ultimately, using washing up liquid might seem like a harmless shortcut, but using it on your car could lead to serious and expensive damage over time. Spending a little more on the right products now could save your thousands in the future.
