Sodium percarbonate is a water-soluble powder widely used to remove stains, whiten laundry, and support hygienic cleaning on fabrics and washable household surfaces. When dissolved in water, it releases oxygen. This reaction helps break down stains and organic residues in a simple and effective way.
If you often deal with yellowed white clothes, stains that remain even after washing, bins that keep unpleasant smells, shower curtains with marks, or surfaces dulled by residues and streaks, you are probably looking for exactly this kind of solution.
However, sodium percarbonate is not designed for heavy degreasing. If you need to remove thick grease layers or stubborn encrustations, a dedicated degreasing detergent will work better.


Key Points from This Article

  • Sodium percarbonate activates in water and releases oxygen.
  • It works well for soaking, household cleaning, and treating washable fabrics and surfaces.
  • It is effective on stains and yellowing, but less suitable for heavy grease.
  • Do not use it on wool, linen, silk, or natural leather.
  • It is ideal if you want a chlorine-free and fragrance-free powder solution.

What Is Sodium Percarbonate?

Sodium percarbonate is a granular powder compound that releases oxygen when dissolved in water.

This chemical reaction makes it useful for:

  • brightening dull whites
  • treating organic stains
  • improving the appearance of fabrics
  • supporting the cleaning of washable surfaces

People often use it as a laundry booster or as a diluted solution for targeted cleaning tasks.


How It Works in Practice

The process is simple.

When the product comes into contact with water, it:

  • dissolves quickly
  • releases oxygen
  • helps loosen stains and lift dirt from surfaces and fabrics

Its stain-removing and whitening action works even at moderate temperatures. At higher temperatures, the hygienic effect becomes stronger.


Household Uses of Sodium Percarbonate

Below you will find the most common and truly effective uses.

Household uses of sodium percarbonate for laundry, soaking and surface cleaning
Common household uses of sodium percarbonate for laundry boosting, soaking and surface cleaning.

1) Laundry in the Washing Machine

If white laundry has turned grey, or stains do not disappear completely, you can add sodium percarbonate together with your detergent.

It is useful when:

  • you want to refresh towels and bed linen
  • stains are light but spread across the fabric
  • you need extra cleaning support

It does not replace detergent. Instead, it boosts the washing performance.

2) Pre-Treating Stains Before Washing

If you have a visible stain on a shirt or on light-coloured fabric:

  1. slightly dampen the area
  2. apply a small amount of product
  3. leave it to work
  4. wash as usual

This simple step can make a big difference when the washing cycle alone is not enough.

3) Soaking Yellowed Clothes

For white fabrics that have lost brightness, soaking often works better than washing alone.

  1. prepare a basin with water
  2. dissolve the product
  3. leave the garment to soak
  4. rinse, then wash normally

This method is especially useful for fabrics that have gradually become dull over time.

4) Cleaning Floors and Hard Surfaces

You can use sodium percarbonate in a diluted solution to clean:

  • washable floors
  • wall tiles and coverings
  • countertops
  • sinks and bathroom fixtures

It works best when dirt consists of light residues, streaks, or organic marks.

On the other hand, if the surface has heavy or layered grease, you should choose a specific degreasing detergent.

5) Bins for Waste Sorting

If your bins keep unpleasant smells or have visible residues:

  1. rinse them first with water
  2. prepare a diluted solution
  3. leave it to work
  4. rinse and dry

This is a simple method for regular maintenance.

6) Fabric Sneakers

To refresh white fabric sneakers:

  1. prepare a solution
  2. apply with a sponge or soak briefly
  3. rinse thoroughly
  4. let them air dry

Avoid delicate materials and natural leather.

7) Shower Curtains and Bath Mats

If you notice humidity marks or stains:

  1. soak the item in a diluted solution
  2. leave it to work
  3. rinse carefully

This is a practical way to keep bathroom accessories cleaner over time.


When NOT to Use It

Sodium percarbonate is not suitable for:

  • wool
  • linen
  • silk
  • natural leather

It is also not recommended on blood stains, because it may create oxidation residues that are harder to remove.

In addition, it is not effective on baked-on grease or heavy encrustations. In those cases, a strong degreasing cleaner will give better results.


How to Choose a Good Sodium Percarbonate

For home use, it is best to choose a granular sodium percarbonate powder that dissolves easily in water and does not contain unnecessary additives. This way, you get a versatile solution for laundry, soaking, and cleaning washable surfaces.

SEIGENICO is a water-soluble granular sodium percarbonate powder designed for laundry and household cleaning when diluted in water. Its simple formulation makes it suitable for the uses described in this guide.


Conclusion

Sodium percarbonate is a reliable solution when you need a strong stain-removing and whitening effect. It works well on yellowing, streaks, and organic residues when used in water-based solutions. For this reason, it is ideal for laundry, soaking, and the regular cleaning of compatible surfaces and household accessories. However, a powerful degreasing detergent is still necessary for heavy grease. In everyday home maintenance, sodium percarbonate remains an excellent support product.

Rust stains on floors are a common issue, especially on outdoor surfaces. These yellowish marks can affect the appearance of stone materials and are often difficult to remove without the right treatment. In many cases, the cause is linked to everyday activities such as garden care. The use of fertilizers and lawn treatments can lead to rust formation due to the presence of iron sulfate.

The team worked on stone surfaces affected by deep rust stains, which required a precise and professional approach to remove them without damaging the material.
