Yellow stains under the armpits are not ordinary stains. They result from a reaction between perspiration, the aluminum contained in deodorant, and bacteria, which attach to the fibers and resist bleach and conventional washing methods.

🌿 Save your clothes and the planet — one wash, zero effort.

We all have a sweater or shirt that we love… but no longer dare to wear. Armpit stains, deodorant, yellowing fibers — we end up putting them at the bottom of the drawer, or worse, in the trash. This is exactly what Claire, a customer, was experiencing: "I was about to throw away my favorite white blouse. Fifteen minutes, a normal wash... and it's perfect again!" When I tried the product created by Pierre, a passionate chemist, I had the same shock. In 15 minutes, the stain had disappeared. No bleach, no scrubbing, no smell. Just clean. That day, I decided that this invention could not die in silence. Today, I continue his work with a single objective: to save clothes and reduce textile waste, one wash at a time. Our biodegradable stain remover works on its own: soak the stain, wait 15 minutes, wash as usual — and that’s it. Stains disappear, fabrics stay soft, and the planet breathes a little easier.

Frequently Asked Questions

WHY BUY

1. Does it work on old stains?

EFFIKACE™ works differently from classic stain removers: it does not just mask the stain, it targets the chemical buildup that has become embedded in the fabric fiber over time (deodorant residue, minerals, sweat, etc.).
Even old stains — present for months, sometimes years — can be considerably reduced, or even completely eliminated after one or a few treatments.

2. Can it damage colors or delicate fabrics?

No.
EFFIKACE™ is bleach-free, free of harsh chemicals, and designed to respect fibers and colors . It works where the stain has formed, without weakening the fabric or altering the dye.
Thousands of garments — pale, dark and delicate — were treated without discoloration or damage when used according to instructions.
As a precaution, we always recommend testing on a discreet area , especially for first-time use or on very delicate fabric.

If the garment can tolerate it, you can use it with confidence.

3. Does it also work on deodorant stains?

Yes.
EFFIKACE™ is specifically designed to act on deodorant residues , whether yellow or white.
It dissolves the buildup left by aluminum salts, minerals, and fixing agents found in many deodorants — the real cause of yellow underarm stains and stiff white marks on dark fabrics.
Result :
  • The yellow stains are reduced or eliminated.
  • the white residue disappears
  • the fabric regains its suppleness and original appearance
Even clothes that you thought were beyond repair can be restored after one or two applications.

4. How long does a bottle last?

It depends on the condition of the clothes being treated.

Thanks to its ultra-concentrated formula , one bottle of EFFIKACE™ generally allows you to restore 10 or more garments .
Light or recent stains require less product, while old or heavily ingrained stains may require a more generous or repeated application.
In all cases, a small amount is sufficient: the product is designed to act effectively without waste , making it a sustainable and economical long-term solution.

5. Is it environmentally friendly?

Yes.

EFFIKACE™ is biodegradable and manufactured locally in Quebec , which reduces both the transport footprint and the overall production impact.
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.
