Oxygen Bleach / Sodium Percarbonate, 1KG

Oxygen Bleach / Sodium Percarbonate, 1KG

Sodium percarbonate is what oxygen bleach actually is: a pure, single-ingredient powder made from sodium carbonate (washing soda) and hydrogen peroxide. Dissolved in warm water, it releases hydrogen peroxide, which lifts stains, brightens whites and freshens fabrics without chlorine and without weakening fibres. It then breaks down into water, oxygen and soda ash.

Add 1 to 2 tablespoons to your laundry to brighten and freshen. For stains, dissolve it in warm water and soak, or make a paste and apply it to the mark. A diluted solution cleans kitchens, bathrooms, decks and outdoor areas. It is considerably more useful than most people realise.

How much oxygen bleach to use

How to use oxygen bleach

In the washing machine

Dissolve the powder in a little warm water first, then add it to the drum with your detergent or soap nuts. Don't sprinkle dry powder straight onto fabric.

Presoaking stains

It works on organic stains such as coffee, tea, wine, fruit juice, food, sauces, grass and blood. Soak for 1 hour or overnight. Hot water speeds up the bleaching, so give cold soaks longer. For a single mark, mix a paste with a little warm water, work it in, then wash.

Around the house

It cleans and deodorises plastics, fibreglass, porcelain, ceramics, wood, carpet and concrete. For the bath and shower, make a paste with hot water, scrub with a cloth or sponge, leave 15 minutes, then rinse. For a deck, scrub with the solution, hose the area down, let it dry, then seal it with a deck oil.

Safety and tips

• Causes serious eye damage and is harmful if swallowed. Avoid contact with eyes, keep out of reach of children and pets, and read the label before use.
• It is an oxidiser. Store it dry, sealed, and away from heat and flammable materials.
• Not suitable for wool, silk or leather. Test coloured fabrics for colourfastness first and follow garment care labels.
• Does not remove rust or hard water mineral deposits.
• Don't mix it with chlorine bleach.
• A mixed solution stays active for about 5 to 6 hours. Pour any leftover down the drain.

Oxygen bleach FAQ

What is sodium percarbonate?

Sodium percarbonate (sodium carbonate peroxyhydrate, CAS 15630-89-4) is a white granular powder made by combining sodium carbonate with hydrogen peroxide. It is the active ingredient in most oxygen bleach and "oxy" stain removers. Ours is 100% sodium percarbonate with nothing added.

Is oxygen bleach the same as chlorine bleach?

No. Chlorine bleach is sodium hypochlorite. Oxygen bleach releases hydrogen peroxide instead, so it whitens and lifts stains without chlorine, without the chlorine smell, and without weakening fabric fibres. It is also safe on most coloured fabrics, but test first.

Is sodium percarbonate safe to use?

Yes, used as directed. The dry powder is a hazardous substance: it can cause serious eye damage and is harmful if swallowed, so handle it with care. Once dissolved and used, it breaks down into water, oxygen and soda ash, leaving no chlorine by-products on fabric or surfaces.

Hot or cold water?

Warm to hot water works best, between 37 and 65°C. It still works in cold water, but more slowly, so soak for longer.

Can I use oxygen bleach with soap nuts?

Yes. Soap nuts contain no bleach, so oxygen bleach is a good partner for keeping whites bright and shifting stains. Add it to the drum with your soap nut wash bag. See how to use soap nuts.

Is it safe for septic tanks?

Yes. Add 1 cup to the toilet and flush it through twice a week.

Does it expire?

Kept dry in its sealed bag, it lasts a long time. Moisture makes it slowly release its oxygen and lose strength, so always reseal the bag.
