The Dirty Truth about Cleaning – Laura Harnett

We’ve talked a lot about non-toxic sprays and detergents in this Newsletter and on the Healthy Home Show Podcast; but what about the tools we use every day to clean …like sponges, cloths, brushes?

You may recognise my latest podcast guest, Laura Harnett , from Dragon’s Den, where she successfully secured investment for her eco cleaning brand, Seep . In this week’s episode, Laura reveals how everyday cleaning tools, from sponges to cloths, are an invisible source of microplastics, hidden chemicals, and unnecessary waste. The good news? With a few smart swaps, you can dramatically reduce your exposure and environmental impact without sacrificing performance.

The Problem No One Sees: Plastic Tools = Microplastics

  • The familiar green-and-yellow sponge scourer sheds millions of microplastic particles over its lifetime (the green polypropylene top and the yellow polyurethane base both fragment as you scrub). Those particles go down the sink, into waterways, and into our homes.

  • Microfibre cloths are, by definition, micro-plastics (usually polyester). They clean brilliantly and last a long time — but release microfibres when used and washed.

  • We handle these tools daily, increasing the chance of exposure and shedding into indoor air and surfaces.

Swap: Seep’s scourer uses wood pulp (cellulose) for the sponge and loofah (a plant that grows on a vine) for the abrasive . It’s durable, effective, and breaks down without microplastics.

 

Performance First, Eco Always

  • Seep’s approach: make tools people would choose because they work and look good — and they just happen to be better for you and the planet.

  • Longevity: Seep’s sponge scourers typically last two months+. You can refresh sponges and “sponge-cloths” in the dishwasher or washing machine to extend life.

  • End-of-life: Aim for home-compostable wherever possible; Seep provides product-by-product end-of-life guidance (e.g., compost cellulose/loofah; recycle copper scourers indefinitely via appropriate streams).

Greenwashing Is Real — Here’s How to Spot It

  • Many “eco-looking” products (brown/green packaging, “bamboo” claims) still contain plastic blends.

  • Seep vets factories, audits materials, and prefers FSC-certified sources (for bamboo, wood pulp, natural rubber).

  • Transparency matters: when early testing once found ~1.5% polyester in a cloth, Seep discontinued it and corrected course. Ethical brands own mistakes and publish improvements.

Look for:

  • Home-compostable certification for disposables

  • FSC for plant-based materials

  • Credible business standards (B Corp), and values-aligned initiatives like Buy Women Built

Rethinking “Clean”: Less Scent, Fewer Antibacterials

We’ve been trained to equate “clean” with strong perfume and constant antibacterial agents that can drive eczema, dermatitis, and unnecessary chemical exposure.

Smarter baseline:

  • Go fragrance-free where you can (Laura’s family skin improved when they did).

  • Skip fabric softener unless essential.

  • Use simple pantry staples for many jobs: lemon, bicarbonate of soda, white vinegar.

  • Reserve antibacterial products for genuine bio-mess (e.g., pet accidents), not daily everything.

Waste Reality Check — and Why “Compostable” Helps

  • UK household waste systems are inconsistent across local authorities. What you can recycle kerbside varies, causing confusion and contamination.

  • A large share of residual waste isn’t landfilled…. it’s incinerated. Designing tools that avoid plastic and are home-compostable helps keep material out of both landfill and the burner.

Health Lens: Lifestyle Still Moves the Needle

During treatment and recovery from breast cancer, Laura learned that lifestyle changes can cut recurrence risk by around 60% — not just medication alone. That means:

  • Regular movement

  • Diverse, colourful whole foods (“eat the rainbow”)

  • Targeted micronutrients (e.g., 1–2 Brazil nuts daily for selenium)

  • Better sleep (hard for many of us, but powerful)

Reducing unnecessary chemical exposure at home, including from cleaning tools, is one practical lever alongside these fundamentals.

Quick Switches You Can Make This Week

  1. Bin the green-and-yellow sponge → Cellulose + loofah scourer (home-compostable end of life).
  2. Retire microfibre for most jobs → Bamboo or cellulose “sponge-cloths.”
  3. Refresh, don’t replace → Pop cloths/sponges in dishwasher/washing machine to extend life.
  4. Go fragrance-free → Particularly for laundry; skip fabric softener.
  5. Pantry power → Keep lemon, bicarb, vinegar handy for everyday cleans.
  6. Check the label → Look for FSChome-compostable, and clear end-of-life instructions.
  7. Plan the end → Compost plant-based tools; recycle metals (e.g., copper scourers) appropriately.

Why This Matters for Healthy Homes & Longevity

“Planet-friendly” and “people-friendly” are the same direction. Microplastics and persistent chemicals don’t belong in our kitchens or our bodies. Choosing non-plastic tools that perform beautifully is a low-friction, high-leverage change — multiplied across every sink, every day.

Key Takeaways

  • Everyday tools shed microplastics. Traditional scourers and microfibre cloths fragment with use and washing.

  • Plant-based tools work — and break down cleanly. Cellulose, loofah, bamboo, and FSC-certified materials are robust alternatives.

  • “Clean” ≠ perfumed + antibacterial. For most daily tasks, fragrance-free products and pantry basics are healthier for skin, air, and microbiome.

  • End-of-life matters. Prioritise home-compostable and recyclable designs; follow brand-specific disposal guidance.

  • Lifestyle is powerful. Alongside low-tox choices, movement, colourful whole foods, micronutrients (e.g., selenium), and sleep materially support long-term health.
