Multi-Use Descaler 1kg


Magic Multi-Use Descaler is a powder concentrate designed to descale and sanitise appliances by removing limescale and mould. It improves the performance of appliances and reduces breakdowns. Ideal for Coffee Machines, Jugs, Steam Irons, Dishwashers, and more.

  • Removes Limescale
  • Cleans and Sanitises
  • Improves Machine Efficiency
  • Ideal for Home or Commercial Use

Limescale, mineral deposits and mould build up on appliances that use water. This build-up is worse if you have hard water as it contains a high mineral content. Some traditional methods can take much longer to achieve results and are unsuitable for some appliances. It is not advisable to use harsh acids, like sulphuric acid, which is hazardous, poisonous and can corrode some surfaces.

Magic Multi-Use Descaler is non-toxic, biodegradable, septic safe, and certified Australian Made & Owned.

  • Safely removes built-up limescale, hard water deposits, and mould
  • Improves the performance and longevity of appliances
  • Reduces energy consumption
  • Helps to prevent element damage

Ideal for:

  • Kettles, Urns, Coffee Machines,
  • Dishwashers,
  • Steam Ovens, Steam Irons,
  • Baby Bottle Sterilisers,
  • Water Coolers
  • Shower Heads and more.

See the How To Use tab for instructions for each appliance.

I used the product according to the instructions, but there are still brown stains or a burnt look at the bottom of the kettle.
This product removes the build-up of lime scale, calcium deposits, bacteria, and mould. Brown stains are usually caused by hard water, which has a higher concentration of minerals. These minerals burn when the water is heated. To avoid these brown stains, use filtered water in your kettle. Unfortunately, Multi-Purpose Descaler is not formulated to remove these mineral stains.

Is Multi-Purpose Descaler dangerous or caustic?
No, it is entirely safe. Multi-Purpose Descaler is non-toxic and biodegradable.

Can Multi-Purpose Descaler be used to clean my electric baby sterilisers?
Yes, use as per the kettle instructions; add the same amount of premixed solution as water as the manufacturer directs. Run the steriliser as usual, and after a complete run, sterilise it with clean water.

What are the ingredients of Multi-Purpose Descaler?
Unfortunately, it is not company policy to hand out formulations of our products. I can tell you it is a blend of various products and is a food-grade – citrus-based formulation that is non-toxic and biodegradable.

Can Multi-Purpose Descaler be used for my washing machine?
Not really. It won’t hurt your washing machine, but it is not aggressive enough to dissolve the scum and calcium build-up that washing machines collect. Instead, use Magic Washing Machine Cleaner. If you haven’t cleaned your machine for a while, use Magic Heavy Duty Washing Machine Disinfectant & Cleaner.

The instructions on the Multi-Purpose Descaler say, “Not suitable for use in Aluminium or Magnesium Alloy kettles”. Then, on the sachet, it says, “Not suitable for use on Aluminium, Enamelled or Pyrex glass kettles”. Can I use it in my Glass Breville Kettle?
We have spoken to Breville, who advised that using the product on your Breville Glass Kettle is okay.

Why is there a funny taste in my coffee after using Multi-Purpose Descaler?
We always recommend rinsing the coffee machine with clean water after using Multi-Purpose Descaler. If you are still concerned, run the Multi-Purpose Descaler through the machine again to remove the stubborn limescale build-up. Sometimes, a build-up of stale coffee granules can also cause unpleasant odours and taste.

Does Multi-Purpose Descaler contain vinegar?
No, our Multi-Purpose Descaler does not contain vinegar. Vinegar is not suitable for some appliances; check your machine’s instructions. Check out our blog on Four (4) things you need to know about cleaning with vinegar before you use vinegar for cleaning. 

Can I use Multi-Purpose Descaler in my Iron?
Yes, you can use Multi-Purpose Descaler to remove the built-up limescale from the inside of your steam iron. Follow the instructions on our website ‘How to Use’ section on Multi-Purpose Descaler.

Can I use Multi-Purpose Descaler on my Aldi Coffee Machine?
Yes, you can; please see ‘How to Use’ for instructions, and refer to the user manual supplied with your coffee machine for instructions specified for your machine.

Can I use the Multi-Purpose Descaler in copper pipes?
Yes, you can, but do not allow the product to sit in the pipes for more than two (2) hours, and the pipes should be flushed after use.

How do I clean my stainless steel thermos with Multi-Purpose Descaler?
Yes, you can. Add the Multi-Purpose Descaler to the thermos and fill it with boiling water. Let stand for 1/2 to 1 hour or so. Open and check to see if it has removed the build-up (you may need to give it a wipeover with a non-scratch scorer…no need to scrub.

Can I use the Multi-Purpose Descaler on my Delonghi automatic coffee machine?
Yes, you can. See the ‘How to Use’ tab on our website for instructions, and refer to the user manual supplied with your coffee machine for instructions specified for your machine.

Will Magic Multi-Purpose Descaler remove iron deposits?
Yes, Magic Multi-Purpose Descaler will remove iron deposits.

Can I use Magic Multi-Purpose Descaler in my glass kettle?
Absolutely. You can watch it remove the scale from your appliance and see the Magic!!

Can I use this product to clean the scale build-up in my ceramic toilet?
Absolutely. The build-up in toilets can be stubborn to remove and may take more than one (1) treatment. Place 1 scoop or 1 sachet into the toilet bowl and leave for as long as possible. We do not recommend pouring boiling water into the toilet bowl as this could cause the ceramic to crack.

How often do I need to descale my kettle?
This depends on your kettle and if you have hard water in your area. Only use the Multi-Purpose Descaler if there is a scale build-up.

Multi-Use Descaler

It works like a charm!
Question; why is it next to impossible to find in any supermarket?

Thank you, Glen. Our Magic Multi-Use Descaler is so versatile and works well. Recently major supermarkets delisted it and are now ranging our liquid version, Magic All Purpose Descaler. https://rubbedin.com.au/product/all-purpose-descaler-250ml/
You can always buy it direct from us here if you can't find it in stores.
