The product works deep down, directly on what causes the stain, 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 stain is different. If a stain is very old or particularly ingrained, a second application may be necessary.

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

Why does this work when others fail?
Yellow underarm stains are not "ordinary stains." They result from a reaction between sweat, the aluminum in deodorants, and bacteria, which bond to the fibers and resist bleach and conventional washing methods. EFFIKACE™ was specifically designed to neutralize this reaction. After 35 years of field testing with real customers, the formula has been perfected to deliver powerful results without damaging fabrics.
How does EFFIKACE™ work?
- Soak the garment.
- Leave on for 15 minutes, without rubbing.
- Put it in the washing machine with the other clothes.
- And just like that, it's all gone.

Frequently Asked Questions
Why choose Effikace Products?
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.
