5 Surprising Ways to Use Electrolysed Water Around the Home

 

Your Water Machine Does More Than You Think — Here's How to Use Every Setting

Most people who purchase a Tokui electrolysed water machine do so for one reason: better drinking water. But a quality ioniser machine produces multiple types of water at different pH levels — and each has distinct, science-backed applications around the home.

If you've only been using your machine for drinking water, you may be getting less than half the value from it. Here are five practical, research-supported ways to use electrolysed water throughout your home — and why eco-conscious Australian families are replacing entire shelves of cleaning products with a single machine.

Understanding Your Machine's pH Settings

A full-featured electrolysed water machine typically produces water across a pH spectrum:

• pH 8.5–9.5 (Strong Alkaline): Drinking water — hydrogen-rich and alkaline
• pH 7.0 (Neutral): Pure water suitable for taking medication or preparing baby formula
• pH 6.0 (Slightly Acidic): Gentle skin toning, beauty water
• pH 4.0–6.0 (Acidic): Cleaning, sanitising, produce washing
• pH 2.5 (Strong Acidic): Powerful natural disinfectant

Each output uses the same tap water input — just processed differently by the electrolysis cell.

1. Natural Surface Disinfectant (pH 2.5)

Strongly acidic electrolysed water at pH 2.5 has well-documented antimicrobial properties. Studies have shown it to be effective against a range of common pathogens including E. coli, Salmonella, and Staphylococcus aureus when used as a surface disinfectant.

Use it to wipe down kitchen benches, cutting boards, bathroom surfaces, and doorknobs. It leaves no chemical residue and is safe around children and pets — a significant advantage over commercial disinfectants containing chlorine compounds or synthetic fragrances.

Tip: Fill the Tokui 300ml spray bottle with pH 2.5 water and store in the kitchen for daily use.

2. Fruit and Vegetable Washing (pH 4.0–6.0)

Mildly acidic electrolysed water is highly effective at removing surface pesticide residues and bacteria from fresh produce. Unlike plain water, its low pH disrupts the cell membranes of surface microbes and helps break down waxy pesticide coatings.

Soak leafy greens or berries for 3–5 minutes in slightly acidic water before rinsing with neutral water. Multiple studies from Japanese agricultural research institutions have shown measurable reductions in surface pesticide levels using this method.

It also has the added benefit of extending the shelf life of certain produce — a separate topic covered in detail in our spinach freshness article.

3. Natural Skin Toner (pH 6.0)

Healthy skin has a naturally slightly acidic pH — typically between 4.5 and 5.5, often referred to as the "acid mantle." Many tap waters and cleansers disrupt this balance. Mildly acidic beauty water at pH 6.0 can be used as a gentle, chemical-free facial toner to help restore surface pH after cleansing.

It is also used in Japan as a hair rinse to smooth the hair cuticle and add shine — the principle is similar to diluted apple cider vinegar rinses, but without the smell or potential for over-acidification.

4. Removing Tough Kitchen Stains (pH 11.5 Strong Alkaline)

Strong alkaline water at high pH is a natural degreaser. The high pH breaks down oils and protein-based stains through saponification — the same chemical principle behind soap. Use it to clean:

• Greasy stovetop and rangehood surfaces
• Oily residue on pots and pans
• Coffee and tea stains on mugs and countertops
• Fresh stains on clothing before laundering

No chemicals, no synthetic surfactants — just ionised water doing what chemistry allows.

5. Safe Preparation Water for Infants (pH 7.0 Neutral)

For parents of young infants, neutral water at pH 7.0 is recommended for preparing formula and administering medications. Unlike the alkaline or acidic outputs, neutral water does not interact with the pH-sensitive compounds in infant formula or certain medications.

This setting gives parents confidence that they are using pure, filtered water — without chlorine, chloramine, or other common tap water additives — for their most sensitive household members.

One Machine, Multiple Roles

The environmental case for an electrolysed water machine goes beyond replacing plastic drinking water bottles. When you factor in the surface cleaners, disinfectant sprays, produce washes, beauty toners, and baby water that a single Tokui machine can replace, the value proposition shifts considerably.

For Australian families looking to reduce household chemical use, cut plastic waste, and invest in a single evidence-backed appliance — electrolysed water technology is one of the most versatile options available.
