Advantages of laundry bleach: - Ensures optimal and natural whitening for both white and colored fabrics, contains no bleach or chlorine. Thoroughly cleans all colored fabrics without fading. Removes stains caused by coffee, tea, red wine, fruit juice, grass, ink, etc. Does not damage elastic fabrics. Formula free of chlorine and optical brighteners that can leave residue on skin and in the environment.

Does it really work from the first wash?

Yes.

EFFIKACE™ Whitening is known for its fast and reliable effectiveness. When used as directed, for very dull whites: one overnight soak is sufficient.

The product works deep down, directly on what causes yellowing, which is why so many customers see a difference from the first use — even on clothes they thought were lost.

Obviously, every fabric and every garment is different. For very old or particularly ingrained yellowing, a second application may be necessary.

Is it safe for all fabrics and all colors?

Yes.

EFFIKACE™ is free of bleach and whitening agents , making it safe for all colors and the vast majority of fabrics when used as directed.

The formula works on the residues responsible for stains without damaging the fibers or the dye. Light, dark, or colored garments can therefore be treated with complete confidence, without risk of discoloration.

As a precaution — especially for first-time use or for very delicate fabrics — we always recommend testing on a discreet area before full treatment.

How do I use it?

Always dilute EFFIKACE laundry whitener in very hot water according to the recommended dosage. Add it to your detergent and start your wash. If added to each of your washes as a replacement for chlorine, it will keep whites and colors at their brightest. It will not damage fabrics.

Traditional agitator washer:

- blanch only: 1 to 2 tablespoons.

- stain removal: 2 to 3 spoonfuls.

- For heavily soiled laundry: 4 to 6 tablespoons. Note: 1 tablespoon = 15 g

HE type front loading washer: Add the product well diluted in the bleach compartment or directly onto the laundry, close the door and start the wash.

Hand washing: 1 to 3 tablespoons, soak as needed, and can even soak overnight. Does not affect colors. Laundry detergent can be added during soaking time.

IMPORTANT: Always dissolve the product in hot water before adding it to the laundry.

Is it safe for fabrics?

Yes.

It restores the whiteness without damaging it.
Beyond its formula, its real ecological advantage is that it extends the lifespan of clothing . By restoring textiles that would otherwise be thrown away, it directly contributes to reducing textile waste and refuse — one of the main sources of household waste.

Fewer clothes thrown away, fewer unnecessary replacements, and more responsible consumption.

Frequently Asked Questions

Why choose Effikace Products?

Can it damage colors or delicate fabrics?

No,
When used according to the instructions.

EFFIKACE™ bleach is chlorine-free, bleach-free and free of harsh oxidizing agents , making it safe for colors and most fabrics .
It works deep down to eliminate residues that dull the fibers, without attacking the pigments or weakening the textiles.
However, as with any laundry product, we recommend avoiding or testing first on:
  • silk,
  • untreated wool,
  • very delicate fabrics or “dry clean only”.

Does it also work on fabrics that have yellowed significantly over several years?

Yes — in the majority of cases.

EFFIKACE™ whitening agent is specially designed to dislodge the progressive buildup that yellows the fibers over time (soap residue, hard water minerals, oxidized dirt).
For very old or heavily yellowed fabrics, we recommend:
  • an overnight soak in very hot water ,
  • Sometimes two successive treatments are needed for optimal results.
The older the yellowing, the longer it may take — but the product is specifically formulated for this type of case.

How long does a bottle last?

It depends on how often you use it and the condition of your laundry.
On average:
  • In regular maintenance (≈ 2 tbsp per wash): a 900g bag lasts approximately 25 to 30 washes .
  • For intensive soaking (very yellowed laundry): one bag allows 10 to 15 complete soaks , depending on the amount of laundry.
Because the formula is concentrated, a small amount is sufficient — there's no need to overdose.

Does it contain bleach or chlorine?

No.

No bleach, no chlorine, no agents that attack the fibers or weaken the seams.

That's why it's safe for cotton, synthetic blends, towels, sheets and most white textiles .



Its ultra-concentrated formula allows less product to be used per application, which means less water, less packaging and less waste .

Above all, by restoring clothes that would otherwise be thrown away, EFFIKACE™ helps extend the lifespan of textiles — one of the most effective ways to reduce the environmental impact of the clothing industry.
Less waste. Less replacement. More clothes saved.



Why do my egg whites turn yellow over time?

Because most traditional “whitening” products mask the problem instead of removing it .

The yellowing is mainly caused by:

  • poorly rinsed detergent residue,
  • hard water minerals,
  • perspiration, body oils, fabric softener.

EFFIKACE™ bleach is formulated to dissolve and remove these deposits from the fiber.
