Most environmental claims on cleaning products are unregulated. "Natural", "non-toxic", "chemical-free" and "eco" have no legal definition in the UK and can be applied to almost anything. A handful of labels do mean something specific, and they are the ones worth looking for.
"Chemical-free" is the clearest tell. Water is a chemical. Any product making that claim is either being careless or hoping you are.
Labels that mean something
EU Ecolabel. A certification scheme with published criteria covering toxicity to aquatic life, biodegradability, packaging and fitness for purpose. Products are independently verified. Among the more rigorous marks you will see on a cleaning product.
Nordic Swan Ecolabel. Similar in approach, with criteria across the product life cycle. Also independently verified.
Cruelty Free International Leaping Bunny. Specifically about animal testing, with a supply chain audit behind it. It says nothing about environmental impact, which is a common misreading.
The Vegan Society trademark. Registered and specific to animal-derived ingredients.
Certified B Corporation. About the company rather than the product, covering social and environmental performance, with reassessment every three years.
Forest Stewardship Council, on paper products. Regulated and meaningful, about forestry rather than cleaning chemistry.
Claims that mean little on their own
"Natural" and "plant-based." Unregulated. Plant-derived surfactants can still be harmful to aquatic life, and plenty of natural substances are hazardous. It is a sourcing claim, not a safety or environmental one.
"Non-toxic." No legal definition. Toxicity depends on dose and route of exposure.
"Chemical-free." Meaningless.
"Biodegradable." Under UK and EU detergent regulations, surfactants in cleaning products already have to meet biodegradability requirements. Advertising it is not a differentiator, it is a description of the legal minimum.
"Made with essential oils." Fragrance rather than function. Worth noting that several essential oils, including tea tree, eucalyptus, citrus, pine and peppermint, are associated with toxicity in cats, so "natural" is not the same as "safe for the household".
"Dermatologically tested." Says a test happened, not what the result was.
Green packaging design. Leaf motifs and kraft paper are art direction.
What actually reduces impact
The uncomfortable finding is that product choice matters less than the behaviours below.
1. Use less. Overdosing is the single biggest source of unnecessary impact. Most people use two or three times the recommended amount of detergent and floor cleaner, which also leaves residue that attracts soil and makes surfaces dirtier faster. Measure.
2. Use fewer products. A degreaser, a limescale remover, a neutral floor cleaner and a general detergent cover nearly everything in a house. The rest is largely the same detergent with different fragrance and a different bottle.
3. Refills and concentrates. Ready-to-use sprays are mostly water, shipped in plastic, across the country. Concentrates and refill pouches cut both packaging and transport substantially, and they are usually cheaper per use.
4. Reusable cloths. Microfibre cloths washed and reused beat disposable wipes on almost every measure. Wash them without fabric softener, which coats the fibres and destroys their function.
5. Wash textiles at lower temperatures where appropriate. Heating water is the dominant energy cost in laundry. The exception is bedding where dust mites are a concern, which benefits from 60°C.
6. Ventilate rather than mask. Air fresheners add volatile organic compounds to indoor air to cover a smell whose source is still there. Opening a window costs nothing and deals with the cause.
7. Keep equipment working. A vacuum with a clogged filter uses the same energy to do far less. Cleaning the filter is free.
8. Repair and maintain rather than replace. The embodied impact of a new vacuum or mop far exceeds the difference between two cleaning products.
The genuinely effective basics
Cheap, effective and low impact for most household tasks:
- White vinegar or citric acid for limescale. Not on natural stone, which is dissolved by acid
- Bicarbonate of soda for gentle abrasion and odour absorption
- Washing-up liquid and hot water for most general cleaning
- Biological washing powder for soaking greasy filters and oven racks
- Microfibre and water for a surprising proportion of dusting and glass
There are jobs these will not do, and pretending otherwise is how people end up scrubbing for an hour with vinegar and giving up. Heavy oven carbon needs a caustic cleaner. Severe limescale needs something stronger than vinegar. Disinfection where genuinely needed, such as after illness, needs an actual disinfectant used with its contact time.
Safety, which matters more in most homes
For households with children or pets, storage and handling matter far more than whether a product is labelled eco.
- Store everything above head height or locked, never under the sink with a token child lock
- Keep products in original labelled containers, and never decant into a drinks bottle
- Never mix bleach with acidic cleaners such as limescale remover, which releases chlorine gas
- Ventilate while using anything strong
- Check essential oil content if you have a cat
- Keep dishwasher tablets locked away, since they are brightly coloured and highly caustic
Asking a cleaning company
Reasonable questions if this matters to you:
- What products do you use, and can I see the list?
- Will you use products I supply instead?
- Do you use concentrates and refills, or ready-to-use sprays?
- Are your cloths reusable or disposable?
- Do you hold safety data sheets for what you use?
That last one is a good general signal, because a company that holds safety data sheets has thought about what it is putting in your home, regardless of what the labels say.
Be sceptical of a company that describes its products as "100% natural" or "completely chemical-free". It is either marketing language or a misunderstanding, and neither is what you want from people handling caustic cleaner in your kitchen.
Frequently asked questions
Are eco products less effective? Some are, some are not. For general cleaning the difference is small. For heavy degreasing, oven carbon and severe limescale, conventional products still outperform.
Is vinegar a disinfectant? Not a reliable one. It has some antimicrobial activity but is not a substitute for a proper disinfectant where disinfection is genuinely needed.
Are refill shops worth it? For packaging and transport impact, yes, and often for cost. Check the product itself is one you would otherwise buy.
What about "septic tank safe"? A meaningful practical claim if you have a septic tank, indicating the product will not disrupt the biological process. Unrelated to broader environmental impact.
Do I need antibacterial cleaner at home? Rarely, for routine cleaning. Detergent and hot water handle everyday soil. Disinfect after illness and around raw meat preparation.
Which single change makes the most difference? Using less of what you already have.
