Nature's Air-Cleaning Process

Hydroxyl radicals naturally form when sunlight reacts with oxygen and water vapour.

Every day, sunlight reacts with oxygen and water vapour in Earth's atmosphere to naturally produce tiny hydroxyl radicals (OH•). These highly reactive molecules help break down many airborne organic compounds as part of nature's continuous air-cleaning process.

Clark Refresh uses professional hydroxyl technology to recreate this natural process indoors, helping reduce lingering odours after cleaning, restoration and renovation projects.

Trusted Across Many Industries

Healthcare Facilities

Professional hydroxyl technology is promoted by the manufacturer for use in healthcare environments where odour management is important.

Hotels & Accommodation

Used to help prepare guest rooms and indoor spaces between occupancies.

Builder Handover

Ideal after renovations and building works to help reduce lingering indoor odours.

Commercial Buildings

Helping create fresher indoor environments for businesses and workplaces.

Myth vs Truth

OH replaces Cleaning

Cleaning removes the source. Hydroxyl treatment helps reduce lingering odours afterwards.

Hydroxyl Works Instantly

Treatment time depends on the property, airflow and odour severity.

Every Odour Is The Same

Every property receives a tailored treatment plan.

It's Only For Fire Damage

Professional hydroxyl technology is also widely used after renovations, tenancy changes, commercial cleaning and property refreshes.

Understanding the Technology

Hydroxyl technology is an advanced odour reduction process that uses naturally occurring hydroxyl radicals to help break down odour-causing compounds in the air and on surfaces.

Hydroxyl radicals are created naturally every day when sunlight interacts with oxygen and water vapour in the atmosphere. Professional hydroxyl generators recreate this natural process indoors, helping to reduce lingering odours after cleaning, repairs or restoration work.

Unlike traditional masking products, hydroxyl technology works by targeting the compounds responsible for many persistent odours. It is widely used by restoration professionals, builders, property managers and commercial facilities as part of a complete odour management process.

Hydroxyl technology has been trusted by restoration professionals, commercial facilities and indoor air quality specialists for many years. It is widely used to help reduce lingering odours in homes, hotels, offices, vehicles and restoration projects.

The underlying hydroxyl technology promoted by the manufacturer is based on technology originally developed by NASA for advanced air purification research, and is also promoted for use in healthcare environments including hospitals and neonatal wards. Clark Refresh uses professional hydroxyl equipment to help reduce lingering indoor odours as part of a complete indoor air refresh process after cleaning, drying or remediation has been completed.

Both technologies are used by restoration professionals to treat odours.

Hydroxyl treatment generally works more gradually but can often be used in occupied environments when operated according to the manufacturer's guidelines. Ozone treatment is typically faster but is generally intended only for unoccupied spaces because ozone can present health risks and may affect certain materials.

When used in accordance with the manufacturer's instructions and for the intended application, hydroxyl generators are widely used by restoration professionals in occupied buildings. Every project is assessed individually, and any operating guidance will always be provided before treatment.

Depending on the machine, environment and treatment plan, hydroxyl technology is commonly used in occupied buildings when operated in accordance with the manufacturer's guidance. We'll discuss your specific situation before recommending treatment.

How It Works

No. Unlike some deodorising methods, hydroxyl treatment is designed to neutralise odour-causing compounds rather than mask them with fragrances or leave a chemical smell behind.

Hydroxyl technology is commonly chosen because it is considered gentler on furnishings, electronics, fabrics and finishes than ozone treatment, making it well suited to homes, offices, hotels and occupied commercial environments.

Treatment time depends on:

  • Size of the area

  • Severity of the odour

  • Airflow

  • Source of contamination

  • Building layout

Some spaces may require only several hours, while more persistent odours may require longer treatment periods. Hydroxyl treatment is generally a slower, continuous process than ozone treatment.

Understanding the Limits

No. Hydroxyl treatment helps address odours associated with mould, but it does not replace mould remediation. If mould is still actively growing, the underlying moisture problem and mould contamination must be professionally addressed first.

No. Hydroxyl treatment is not a substitute for cleaning, drying, mould remediation or removing contaminated materials. It is most effective once the source of the odour has been addressed, helping eliminate lingering odours that remain afterwards.
