Less Detergent, Better Results – Why Less Really Is More When It Comes to Laundry

If you’re like most people, you probably believe that more detergent equals cleaner clothes. It’s a simple equation, right? Extra dirty load? Add a bit more. Gym kit? Splash in an extra glug for good measure. Bedding? Why not top it up again just in case?

But here’s the surprising truth: using less detergent delivers better laundry results.

We see it all the time in online forum posts, folk puzzled by dull fabrics, lingering odours, or stiff towels, when the real culprit is hiding in plain sight: too much detergent.

Let’s break down why less really is more—and how a simple change can transform your laundry routine.

When “Just a Bit More” Goes Wrong (A Tale of Liquid… and Powder overdosing)

We’ve all got that one friend (or maybe we are that friend) who believes in a generous pour or an extra scoop!

Take Dave, for example. Dave decided his muddy football kit needed “extra help,” so he went in with a confident triple glug of detergent. The result? Not the fresh, clean kit he imagined – but a washing machine that looked like it was auditioning for a bubble bath commercial. Foam started creeping out of the drawer, down the front of the machine, and onto the floor like a slow-motion disaster. His kit? Still not clean – just soapy, blotchy and very confused.

Then there’s the classic powder situation.

A house share story: one well-meaning flatmate thought the scoop size was more of a “suggestion” than a rule. Instead of one scoop, they added two heaped ones “for good measure.” The wash finished, the clothes came out… and every dark item looked like it had been dusted with flour. Black jeans turned grey, t-shirts had streaks, and everything needed rewashing – this time without the over enthusiasm.

The lesson? Laundry isn’t improved by enthusiasm – it’s improved by accuracy.

What Happens When You Overdose Your Laundry

Imagine washing your hair but not rinsing out all the shampoo. It would feel sticky, heavy, and far from clean.

The same thing happens to your clothes.

Here’s what excess detergent can do:

1. Residue Build-Up

Soap left behind creates a film on fabrics, making them look dull and feel rough.

2. Odour Trapping

Instead of eliminating smells, residue traps bacteria – especially in activewear.

3. Reduced Absorbency

Too much detergent can make towels less absorbent (the exact opposite of what you want).

4. Machine Problems

Over time, buildup can clog your washing machine, leading to inefficiency and even breakdowns.

Why Less Detergent Works Better

Using less detergent isn’t just good for your clothes—it’s better for:

• Your wallet – detergent lasts longer
• Your washing machine – fewer maintenance issues
• The environment – less chemical run off

It’s a small change with a surprisingly big impact.

Using the correct amount – less than you think allows your washing machine to do its job properly.

When detergent is used sparingly

• It rinses out completely
• Fabrics stay soft and breathable
• Colours appear brighter
• Clothes genuinely smell fresh

It’s not about cutting corners—it’s about precision.

Think of it like cooking: too much seasoning ruins the dish, but the right amount brings everything together perfectly.

The “Capful Confusion” Problem

Let’s be honest—detergent caps are not the clearest measuring tools.

Many people unintentionally use double or even triple the recommended amount. Add in soft water (common in parts of the UK) and modern efficient washing machines, and suddenly you’re massively overdosing every wash.

One memorable moment many people relate to:

“I realised I’d been filling to the top line for years… turns out that line was for industrial loads!”

You don’t need nearly as much as you think.

• Light loads / lightly soiled clothes: Use less than the recommended amount
• Normal loads: Stick to the lower end of the guidelines
• Heavy loads / very dirty items: Slightly increase—but don’t double

And remember:

• Modern detergents are concentrated
• Newer machines use less water – therefore what matters is how long the programme runs so that all fabric can be spend equal amounts of time in detergent and water.
• Soft water areas require even less detergent

Real-Life Laundry Wins from Using Less

We’ve seen countless examples where reducing detergent made a huge difference:

• School uniforms staying fresh all day
• Gym kit losing that stubborn “washed-but-not-clean” smell
• Towels regaining their softness and absorbency

Sometimes, the fix isn’t adding more – it’s taking a step back.

A Smarter, More Sustainable Approach

Using less detergent isn’t just good for your clothes—it’s better for:

• Your wallet – detergent lasts longer
• Your washing machine – fewer maintenance issues
• The environment – less chemical run off

It’s a small change with a surprisingly big impact.
