Multi-purpose cleaners

15nov multi purpose cleaners hero default

Cleaning the kitchen, bathroom or laundry?

Multi-purpose cleaners are designed to be used on multiple types of surfaces, meaning you don’t need a specific cleaner for a specific area of your home. In our test of 15 multi-purpose cleaners, one wiped out the competition.

Our test

White tiles are covered in a greasy soil and, following the manufacturer’s instructions on applying the cleaner, we used a mechanical arm to clean the tile. The tile’s cleanliness is then checked with a spectrophotometer. The test is repeated 8 times and the results are averaged.

For spray cleaners, where instructions stated, we applied the cleaner to the tile and left it for the designated time before scrubbing the tile clean. Not all cleaners had application directions. In those cases, we applied the cleaner to a damp sponge before placing the sponge on the tile and scrubbing the tile clean.

For wipe cleaners, we attached the wipe to a sponge on the mechanical scrubbing arm and then scrubbed the tile.

Specialised cleaners

A few products in our test are marketed for specific purposes, such as spot or stain removal, grease removal and bleaching. But all of the cleaners in our test can be used on multiple surfaces. We think you should see through the name and use them as multi-purpose cleaners.

You might want a dedicated kitchen or bathroom cleaner for those areas of the house. Check the ingredients list: a dedicated cleaner can have the same ingredients as a multi-purpose cleaner, and just be labelled differently.

Making your own multi-purpose cleaner

Pour some vinegar into a spray bottle. They are available from supermarkets, hardware stores and garden centres, or you can re-use a clean bottle. Make sure to clearly mark it as vinegar or cleaner and keep it out of reach of children. We recommend storing the baking soda in an air-tight container, like a spice shaker. This makes it easier to apply and being air-tight means the baking soda won’t absorb moisture from the air. We also suggest having a second spray bottle of water, for rinsing off after cleaning.

For horizontal surfaces:

  1. For each tile, sprinkle a small amount of baking soda (about ¼ of a teaspoon) on the area to be cleaned.
  2. Spray a few sprays of vinegar (about 3 teaspoons worth).
  3. Once the baking soda starts foaming, scrub the surface.
  4. Rinse with water and wipe with a clean cloth.

For vertical surfaces:

  1. For each tile, sprinkle the baking soda on a cloth.
  2. Spray a few sprays of vinegar onto the cloth and immediately start cleaning the tile.
  3. Rinse with water and wipe with a clean cloth.

Don’t use malt or red wine vinegar. White wine vinegar won’t stain any surfaces, but other vinegars might.

Don’t pre-mix the ingredients. The baking soda will dilute in the vinegar mixture, its effervescence will be lost and you’ll probably recreate that school science experiment of making a volcano.

Fragrances

Most cleaners are designed to leave a pleasant smell. Our home-made cleaner had an obvious vinegar fragrance, but you can mask it by adding ingredients such as citrus juice, vanilla or an essential oil. We tried all of these and found adding citrus juice worked the best (we used lemon). However, adding anything to the mixture affects how well it cleans, so try a test batch first.

A soda by any other name

Baking soda is known by many names, but it’s all the same product:

  • Bicarbonate soda
  • Bi-carbonate soda
  • Bi-carb
  • Bread soda
  • Sodium bicarbonate
  • Sodium hydrogen carbonate

Spot test

Whenever using a cleaner for the first time, check it’s safe for your surfaces.

Follow the instructions on the label and spray a small amount the size of a coin onto the surface you want to clean (do this in an area where it won’t matter if it gets damaged). Wait a few hours to see if the product harms the surface.

Surfaces to avoid

Most multi-purpose cleaners shouldn’t be used on metals or unfinished surfaces.

Always check the pack to see which other surfaces should be avoided – we found a wide variety of “unsafe” surfaces listed.

Unless the product’s label specifically says you can, you shouldn’t use multi-purpose cleaners on these surfaces:

  • Acrylic plastics
  • Aluminium
  • Brass
  • Carpet
  • Clear plastics
  • Copper
  • Cracked and damaged surfaces
  • Fabric
  • Granite
  • Halogen hobs
  • Hot surfaces
  • Lacquered surfaces
  • Leather
  • Marble
  • Natural stone
  • Non-glazed surfaces
  • Soft porous surfaces
  • Suede
  • Terrazzo
  • Unfinished wood
  • Unwaxed vinyl
  • Vitroceramics

Claims

We list some of the claims made on the packaging of multi-purpose cleaners but haven’t tested them.

Biodegradable

Surfactants can have adverse effects on the environment, but “biodegradable” ones will break down and have little effect. There is an Australian standard, AS4351, some manufacturers may follow but this only applies to surfactants. There are no guarantees the other ingredients are biodegradable.

Safe for septic tanks

If you have a septic tank, it can be hard finding household cleaners that are safe to flush down the drain. Cleaners can contain harsh chemicals that can damage a septic tank. We suggest contacting your septic tank manufacturer to see what it recommends.

The wastewater (grey water) is safe

This means the waste, or “grey”, water is safe for other uses, such as watering the garden. If you are using grey water in your garden, we suggest not using it on food that will be eaten raw.

Antibacterial

Some cleaners state they kill a certain percentage of bacteria, but there is little evidence antibacterial cleaners stop the spread of bacteria in a home. There is even the risk they contribute to antibiotic resistance in the environment.

Made from natural ingredients

This claim may only apply to some ingredients in the cleaner, and may not mean the entire product is made from plant-based products. There’s no standard against which to measure these claims.

Phosphate free

Usually listed on laundry detergents, this claim is best accompanied by a minimum phosphate percentage. See our article on unhelpful “green” claims for more about phosphates in dishwashing liquids.

Safety first

“Natural” doesn’t mean safe. “Natural” ingredients, even fragrances, can be harmful.

Always keep your cleaners away from children — ideally in a high or locked cupboard.

If anyone swallows cleaning product, immediately rinse out their mouth with water and phone your doctor or the National Poisons Centre (0800 POISON).
