Persistent odors in the home can be very bothersome. Think of cat urine in the carpet, musty smells in an old sofa, smoke in curtains, or lingering food odors in the kitchen. These odors often penetrate deeply into materials, making air sprays or home remedies insufficient.

But which products are truly effective against these stubborn odors? In this article, we discuss the most effective solutions and why some products work better than others.

Why are some odors so persistent?

Before we discuss the right solutions, it's important to understand why certain odors are so difficult to remove. Odors arise from volatile organic compounds (VOCs) that can lodge deep in pores, textile fibers, or upholstery. If these compounds aren't thoroughly broken down, they remain active in the room—sometimes even after multiple cleaning attempts.

Urine, smoke, mold, grease, and pet odors in particular are known as "persistent" odors that can only be removed with specialized products.

1. Enzymatic cleaners

One of the most effective remedies for stubborn odors is enzymatic odor eliminators . These products contain natural enzymes and bacteria that break down odor-causing organic compounds at the molecular level.

For example, cat urine contains proteins and ammonia that soak into the carpet. An enzymatic cleaner essentially "eats" these proteins instead of masking them. This eliminates the odor permanently, not temporarily.

Advantages:

• Attacks the source of the odor
• Safe for use on textiles, carpets, furniture
• Not harmful to humans or pets (when used correctly)

At Izyclean.eu you will find various enzymatic products that are suitable for both domestic and professional use.

2. Active oxygen or ozone purifiers

For very stubborn odors, such as smoke or mold, ozone cleaners or active oxygen products can be used. These break down odor components through oxidation, neutralizing even the most pungent smells.

This type of cleaning is often used in cars, hotel rooms or homes where there has been prolonged smoke nuisance.

Caution: These are powerful products that should be used with caution. They are generally less suitable for daily use in a household with children or pets, unless specifically formulated for this purpose.

3. Odour neutralisers based on micro-organisms

Some products contain beneficial bacteria (probiotics) that displace odor sources by restoring a healthy microbial balance. This type of odor eliminator is particularly suitable for long-term odor neutralization in damp areas such as bathrooms or basements.

Although they work somewhat slower than enzymatic agents, they have a long-lasting effect and are very environmentally friendly.

4. Deep cleaners for upholstery and carpet

Stubborn odors often penetrate deeply into furniture, curtains, or carpeting. A standard surface spray isn't sufficient in such cases. Deep cleaners are needed: liquid products that penetrate deep into the fabric, loosen, and neutralize odor components.

Some products can be used in combination with carpet cleaning machines or injection/extraction systems for professional results.

5. Adsorbents such as activated carbon

For odors in enclosed spaces like closets, refrigerators, or cars, odor-absorbing products like activated carbon, bamboo charcoal, or silica gel are very effective. These products absorb odor molecules and neutralize the air without releasing any odor themselves.

Although they do not have a cleansing effect, they are ideal as support after deep cleansing.

What doesn't work (or only temporarily)?

• Air fresheners: mask the odor, but do not solve the problem.
• Vinegar or baking soda: can reduce surface odors, but are not powerful enough for deep-seated sources of odor.
• Bleach: kills bacteria, but is not odor-reducing and can damage textiles.

Conclusion

Persistent odors don't disappear on their own and require a targeted approach. The most effective solution depends on the cause, the surface area, and the severity of the odor. Enzymatic cleaners remain the first choice for organic odor sources like urine or vomit, while ozone or active oxygen are better suited for smoke and mold.

At Izyclean.eu , you'll find a carefully curated range of odor removers and cleaners that work. Whether it's a persistent smell in your home, car, or office, the right products will help you tackle the problem at its root.
