Soak & Stain Remover

Soak & Stain Remover

🌱 An oxygen-based solution for whitening, stain removal and deep laundry cleaning

 

When it comes to whitening whites and tackling stubborn stains, there’s one ingredient I reach for every time: sodium percarbonate.

It’s the same active ingredient found in commercial laundry soakers, just without the fillers, perfumes, optical brighteners, or unnecessary extras. On its own, sodium percarbonate is a far cleaner and more transparent option - and it does the job extremely well.

This solution relies on oxygen cleaning, not chlorine bleach. That’s why it’s effective, colour-safe, and much gentler on fabrics and the environment.

This solution isn’t about overpowering stains - it’s about breaking them down.

 

How oxygen cleaning works in laundry

When sodium percarbonate dissolves in water, it breaks down into:

  • Washing soda (alkalinity)
  • Oxygen (the active cleaner)

It’s the release of oxygen that lifts stains, removes odours, and brightens fabrics. Oxygen breaks down organic matter at a molecular level, which is why this method works so well on food, sweat, body oils, and general build-up.

Because this process doesn’t rely on chlorine, it won’t strip dyes or weaken fibres in the same way bleach does.

 

What this solution is used for

This oxygen-based solution works best for:

  • Whitening whites
  • Brightening colours
  • Removing stubborn or set-in stains
  • Deodorising laundry
  • Deep cleaning fabrics

It’s particularly useful when regular washing isn’t enough and fabrics need a reset, not more detergent.

 

Important use notes

  • Always dissolve sodium percarbonate fully before use
  • Hot water is essential for activation
  • Do not use on delicate fabrics such as wool or silk
  • Avoid mixing with acids or chlorine bleach

Oxidation can weaken animal fibres, so this solution is best reserved for cottons, linens, and durable fabrics.

 

Tips for best results

Hot water is key. Sodium percarbonate activates properly above 40°C, releasing oxygen bubbles that penetrate fabric fibres and lift stains more effectively.

Giving the solution time to work matters more than using extra product.

Recipe & Instructions

Ingredient

  • sodium percarbonate

Methods

For Soaking
Add 1–2 tablespoons of sodium percarbonate to a bucket or sink of hot water. Water temperature between 40–60°C is ideal. Stir until fully dissolved before adding laundry. Submerge items and soak for several hours, or overnight for tougher stains.

For stain spot treatment
Mix a small amount of sodium percarbonate with hot water to form a loose paste. Apply directly to the stain and allow it to sit for 15–20 minutes, then wash as normal.

For laundry boosting
Add 1 tablespoon directly to the washing machine drum along with your regular wash.This helps lift residue, brighten loads, and improve overall cleaning results.

For household use
Sodium percarbonate isn’t limited to laundry. The same oxygen-releasing action makes it useful for:

  • Soaking chopping boards
  • Removing tea and coffee stains from mugs
  • Cleaning bins or containers
  • Refreshing outdoor items

Is sodium percarbonate the same as bleach?
No. Sodium percarbonate is an oxygen-based cleaner, not chlorine bleach. It releases oxygen in water, which lifts stains and odours without the harsh fumes or colour damage associated with bleach.

Can I use this on coloured clothes?
Yes, on colourfast fabrics. Oxygen cleaning is generally colour-safe, but always spot-test if you’re unsure, especially on darker or dyed items.

Does it work in cold water?
Not effectively. Sodium percarbonate needs warm to hot water to activate properly. Water temperatures above 40°C give the best results.

Can I use this on wool or silk?
No. Oxidation can weaken animal fibres. This solution is best reserved for cottons, linens, and durable fabrics.

Is it safe for septic systems?
When used for normal household laundry and rinsed properly, sodium percarbonate is suitable for septic systems.
