Natural Cleaning Products: Are They Actually Better For You? Here's What the Science Says

Yes, natural cleaning products are genuinely better for your health, and the research backs it up. The main reason is simple: conventional cleaners flood your home's air with hazardous chemicals every time you use them. The best natural cleaning products get the job done without that invisible side effect. It's not a wellness trend or clever marketing — it's chemistry.

Scientists are increasingly pointing to the risks of the chemical soup we create in our homes just by cleaning. As Alexis Temkin, a senior toxicologist at the Environmental Working Group (EWG), puts it: "This study is a wake-up call for consumers, researchers and regulators to be more aware of the potential risks associated with the numerous chemicals entering our indoor air." That's a scientist telling you your cleaning cupboard might be a problem. Worth paying attention to.

What's Really Hiding in Your Cleaning Spray?

The air inside our homes can be two to five times more polluted than the air outside — and a major reason for this is conventional cleaning products. These products release Volatile Organic Compounds (VOCs), chemicals that easily evaporate into the air at room temperature. You know that sharp, "clean" smell from a disinfectant spray? That's often a cloud of VOCs you're breathing straight in.

A 2023 peer-reviewed study in the journal Chemosphere, conducted by EWG scientists, analysed 30 common cleaning products and found they released a staggering 530 unique VOCs in total. Of those, 193 were identified as hazardous, with links to respiratory damage, increased cancer risk, and reproductive issues. The average conventional product emitted 22 hazardous chemicals per use. That's a lot of nasty stuff to breathe in just to get a shiny benchtop.

The same study found that products labelled "green" and "fragrance-free" emitted nearly eight times fewer VOCs than conventional ones, and averaged just four hazardous chemicals per product. The difference is significant. Choosing better products is one of the simplest ways to improve the air quality in your home, and you don't need to do anything dramatic to make it happen.

The Proof is in the Pudding (or the Air Sample)

Knowing that VOCs are bad is one thing. Seeing what happens when you actually stop using them is another. A 2021 study from UC Berkeley gave us exactly that. Researchers followed a group of women who switched from their regular cleaning products to green alternatives for just one week, wearing personal air monitors while they cleaned.

The results were remarkable. The women's exposure to a range of carcinogenic and endocrine-disrupting chemicals dropped sharply. Most notably, there was an 86% decrease in exposure to chloroform, a probable carcinogen that forms when chlorine bleach reacts with organic matter. One week. One swap. An 86% reduction. That's not a small thing.

This matters especially for families with young children, since some studies link higher use of certain indoor cleaners during pregnancy and early childhood to a greater risk of asthma and wheezing. And for anyone who cleans regularly, the long-term picture is worth knowing: people who work in the cleaning industry have a 50% higher risk of developing asthma and a 43% higher risk of chronic obstructive pulmonary disease compared to the general population. You might not be cleaning professionally, but daily, low-level exposure at home adds up over years.

But Do Natural Cleaning Products Actually Work?

This is the big question. For years, we've been conditioned to believe that you need harsh, industrial-strength chemicals to properly clean and disinfect. That belief is outdated. Natural cleaning products that actually work are genuinely effective when formulated correctly with quality ingredients.

Many plant-derived ingredients are serious performers. For example:

• Citric Acid: Naturally found in citrus fruits, it cuts through soap scum, mineral deposits, and hard water stains with ease.
• Plant-based Surfactants: Derived from sources like coconut, these create the cleaning action that lifts dirt and grease off surfaces.
• Essential Oils: Eucalyptus, citrus, and tea tree oil all have natural antibacterial and antifungal properties, leaving behind a genuinely fresh scent rather than a synthetic chemical one.
• Sodium Bicarbonate: Good old baking soda is a mild abrasive that tackles grime without scratching surfaces.

The key is quality formulation. Not all products labelled "natural" are created equal — some are more greenwash than green. That's why it pays to look for products with transparent ingredient lists and proper third-party recognition.

Good Change's Bottle For Good refill tablets are a good example of this done right. They're made with NZ botanicals and essential oils, formulated to actually clean, and come in a beautiful glass bottle that you keep and refill rather than throw away. The average household gets through 30 plastic cleaning bottles a year — this system replaces all of them. Pair it with our Eco Cloths, made from natural wood pulp and cotton with zero microplastics, and you've got a cleaning setup that's better for your health, your home, and your conscience.

Cleaning doesn't have to be a chemical event. It can be simple, effective, and genuinely good for the people doing it.

Frequently Asked Questions

Are natural cleaning products as effective as chemical cleaners?

Yes. High-quality natural cleaners use powerful plant-based ingredients and essential oils that cut through grease, grime, and soap scum effectively. The key is choosing well-formulated products with transparent ingredient lists, not just anything with "natural" on the label.

What does it mean for a cleaning product to be 'natural' or 'eco-friendly'?

Generally, 'natural' means ingredients are derived from plants and minerals, not synthetically created in a lab. 'Eco-friendly' is a broader term that considers the product's entire lifecycle, from sourcing to packaging and disposal. Look for brands that are transparent about both.

What are the best natural cleaning products in NZ?

The best natural cleaning products in NZ are those that are transparent about their ingredients, use sustainable packaging, and are proven to work. Look for local brands that offer refillable solutions and are upfront about their commitment to being non-toxic and eco-friendly. Many large corporate brands are using the "eco" terms more freely, so for brands to trust, go for the ones that have a solid founder story or a passionate person behind who truly cares about your health. 

How do I make a simple and effective natural all-purpose cleaner?

A simple DIY cleaner can be made with one part white vinegar to one part water in a spray bottle, with a few drops of essential oil (like lemon or eucalyptus) for scent. However, for a properly formulated, shelf-stable option, a pre-made concentrate or tablet system is often more effective and convenient.

What is the environmental impact of using conventional cleaning products?

Conventional cleaners contribute to indoor air pollution through VOCs, and their chemical ingredients can harm aquatic life when washed down the drain. The single-use plastic bottles also create a huge amount of landfill waste. Choosing refillable, biodegradable alternatives significantly reduces this impact.
