Removing unpleasant odours — a permanent solution, no masking

Bio-enzymatic odour neutralization that breaks down the source at the molecular level. For restaurants, hotels, industry, sewer systems and residential buildings.

Unpleasant odour removal
in Serbia

Unpleasant odours in buildings and rooms are usually a sign of a more serious problem — organic contamination, bacterial decomposition, sewer leaks, inadequate ventilation or chronic lapses in hygiene. Conventional 'air fresheners' only mask the symptom, while the problem stays and gets worse. BioClean by EZO Green uses a biological approach that breaks down the cause of the odour at the molecular level.

Our products contain specific strains of bacteria and enzymes that attack the organic matter the odour comes from — oils, fats, proteins and ammonium salts from plant and animal waste. Once the source has been broken down, the odour physically cannot exist. This is a permanent solution, unlike aerosol sprays, which only have a temporary effect.

We offer dedicated programmes for different types of premises — hospitality venues (kitchens, fridges, drains), hotels (rooms after smoking or pets), industrial plants (organic waste, fermentation), sewer systems (septic tanks, manholes, collectors) and residential buildings (basements, cellars, old furniture). The treatments are safe for people and animals.

unpleasant odour removal

The complete package — biological products, certified team, documentation.

Restaurant and kitchen deodorization

A dedicated programme for hospitality venues — the most common odour sources are kitchen drains, grease separators and organic waste containers. Treatment includes deodorizing the premises and applying products in problem areas (drains, separators) for long-term control.

Hotels — rooms and common areas

Hotel rooms after guests who smoked, had pets with them or left organic waste behind need treatment before the next booking. Our programme covers complete deodorization of the room, the ventilation and individual items (furniture, curtains).

Industrial odour sources

Factories with organic processes (food industry, farms, biogas) and chemical fumes — specialized programmes. We work on ventilation systems, fixed sources and the site perimeter.

Sewer odours

The most common source of odours in many buildings. Treatment involves applying biological products in drains, septic tanks and collection channels.

Residential — basements, rooms

For private flats and houses with persistent odours (basements, rooms that have been shut up for a long time, old furniture, damp). The programme is tailored to the specific cause — damp odours need a different approach from pet odours or tobacco smoke.

Emergency treatments (smoke, fire, water)

After a fire, a flood or a long-term water leak — specific odours that have soaked into the building structure. These call for more intensive treatment with multi-purpose products.

What working
with us looks like

From the first call to the final documentation — a transparent, documented and compliant process.

01

Source identification

A specialist comes out to assess — identifies the odour source, classifies its type (organic, chemical, damp, biological) and proposes a specific programme.

02

Plan and preparation

A treatment plan based on the premises and the source. Preparing the room (ventilation, protecting sensitive items) and selecting specific products.

03

Product application

Products are applied by hand, by spray or with a fogger (depending on the space). The products come into contact with the odour source.

04

Bio-treatment activation

Over the next 24–72 hours — bacteria and enzymes break down the organic matter the odour comes from. The room is ventilated.

05

Check and recommendations

After 7 days — results check. For complex cases — a repeat treatment. Recommendations for long-term prevention.

Questions
we get most often

How long does an odour treatment take?
For spaces up to 100 m² — usually 1–2 hours to apply, with results in 6–24 hours. For larger premises and complex cases — 3–7 days to full effect. Sewer treatments — results over the following 7–14 days.
Can I use the room straight after treatment?
It depends on the product. Most of our applications allow normal use of the room 2–4 hours after application. For certain intensive treatments (smoke-filled rooms after a fire) — the room must be vacated for 24 hours.
Does the treatment create its own smell or leave a chemical trace?
No. Our biological products have no harsh chemical smell. Some products have light essential oil notes (lemon, eucalyptus) that fade within 2–3 hours. They leave no chemical residue.
What if the odours come back?
For organic odours whose source has been completely removed — a return is unlikely. If they do come back — it means the source is still active (a leak, waste being left to build up). In that case we offer a repeat treatment + identification of the structural cause.
How much does a treatment cost?
It depends on the size of the space, the type of odour and the complexity. Standard residential room (up to 50 m²) — fixed price available on request. Industrial and commercial premises — priced after assessment. Regular prevention contracts are significantly cheaper.
Which products do you use?
Our EZO Commercial line of biological products — EzoBin, EzoCompost, EzoDrain, EzoAnimal and other specific products, depending on the source. All are 100% biodegradable and safe for people, animals and food surfaces (after rinsing).
