Eco- sustainability made simple: tips and reviews for a green life

Sodium percarbonate, the natural alternative to bleach

Sodium percarbonate , a completely natural ally to always have at home for eco-logical cleaning.

If cleaning is your weak point and you would like to try to make it greener, this article is for you.

Have you ever heard of sodium percarbonate ?

No, not bicarbonate, but sodium percarbonate .

Read on if you are curious about what it is and what are its many uses at home to make your cleaning more sustainable.

Percarbonate what it is and why to use it at home

Sodium percarbonate  is a natural whitener and appears as small white water-soluble grains.

Once immersed in water, the percarbonate splits into calcium perborate and hydrogen peroxide (in fact it is called sodium percarbonate with active oxygen).

Its whitening and sanitizing action already occurs at 30-40 degrees, but increases with the temperature of the water in which it is immersed.

Unlike other substances with similar names, such as sodium perborate and sodium borate, sodium percarbonate is not polluting or harmful to people.

Its whitening action makes it a valid natural substitute for bleach which instead pollutes the water and is also toxic for us.

Percarbonate and sodium bicarbonate: differences

Let’s see what are the differences between percarbonate and bicarbonate , two natural substances that can be exchanged with each other.

Let’s start with baking soda which, as you know, has a thousand different uses, for cleaning, for personal care, for clothes, for food.

Baking soda is easily found in the supermarket at a very low price and comes as a water-soluble white powder with several properties:

  • cleaning
  • sanitizing
  • deodorant

It seems simplistic to write like this, but it can be used on a myriad of surfaces, materials and environments, and it is also ingestible (unlike percarbonate ).

However, we do not dwell on the uses of bicarbonate, because we want you to discover the properties of sodium percarbonate :

  • whitening
  • antibacterial
  • antifungal
  • disinfectant
  • stain remover

Now that you know its properties, let’s find out what are the domestic uses of sodium percarbonate , to be able to say goodbye to polluting products such as bleach!

Sodium percarbonate for domestic use

Sodium percarbonate is a great ally in cleaning and you will wonder how you managed without it once you discover all its uses, so here is a list of home uses of sodium percarbonate .


For hand washing just one tablespoon of percarbonate added to the lukewarm water in which you soaked the clothes and then proceed to wash them.

Machine wash

It is mistakenly thought that percarbonate hardens clothes, but it is just the opposite: used together with the detergent, the soluble sequestrants, phosphonates and silicates contained in it soften the water and allow you to save on laundry, also reducing the amount of detergent needed and increasing its effectiveness.

How much to use? Soon said:

  • a spoon in the detergent compartment, if the clothes are very dirty
  • two spoons directly into the clothes drum

Pre-treat stains

White or particularly dirty garments (such as washable diapers ) with stains to be pre-treated can be soaked for two hours, adding a spoonful of percarbonate , instead an hour will suffice for colored garments.

If you do not want to soak the garments you can directly put a little percarbonate powder on the stain and add a little warm water, leave to act and then wash as usual.


Thanks to its sanitizing and softening action of the hardest waters, percarbonate can also be used in the dishwasher, putting 25 gr (a spoon) together with the DIY tablets or the eco detergent you are using.

Surface cleaning

Tiles, floors and stoves can be cleaned using the sanitizing action of percarbonate : two teaspoons in half a liter of water, shake and pour into a spray bottle. Sprayed on the surfaces, it is then treated with a dry cloth.


Even on sanitary ware, as for surfaces, just dissolve two teaspoons of percarbonate in half a liter of water, shake and pour into a spray bottle. Spray on the bathroom fixtures and then treat with a dry cloth.

After having seen how and where to use sodium percarbonate , let’s see where it is better NOT to use it ever.

When NOT to use Sodium Percarbonate

In general, sodium percarbonate should be used on all stains sensitive to oxidation (to the action of active oxygen), including sweat stains, grass or red wine stains.

Some stains, on the other hand, should not be treated with sodium percarbonate at all , it is the case of grease stains and blood stains: in fact the percarbonate would only fix the iron of the blood inside the tissues.

Then there are fabrics and materials on which it is better not to use percarbonate and they are:

  • silk
  • wool
  • skin
  • delicate fabrics
  • dark fabrics

Where to buy percarbonate

At this point you are wondering:

“But where can you buy sodium percarbonate ?”

We know that for many, percarbonate is not yet very well known and also that, unlike other natural products, it is not easily found in shops or supermarkets.

In fact, it is easier to come across products based on percarbonate than to find pure sodium percarbonate , the one we are talking about in this article.

And above all, it is a product that replaces a really toxic, polluting and overly abused one, namely bleach.
