Essential Equipment Used by Crime Scene Cleaners

Crime scene cleaning is not your average janitorial job; it demands a suite of specialised tools and equipment to ensure every trace of the incident is effectively eradicated.

From the unseen dangers lurking in bloodborne pathogens to the visible aftermath of a traumatic event, these cleaners are equipped to tackle it all with precision and safety.

Here’s a closer look at the arsenal of tools they bring to every crime scene.

Personal Protective Equipment (PPE)

Crime scene cleaners wear full-body suits, durable gloves, respirators or masks, and safety goggles to protect themselves from biohazards and chemicals. This PPE is vital to prevent any direct contact with hazardous materials, ensuring the cleaners’ safety as they navigate potentially life-threatening contaminants.

Cleaning Tools

Effective cleaning at crime scenes requires a variety of tools:

  • Mops and buckets for general cleaning, ensuring that larger areas can be sanitised efficiently.
  • Scrapers and sponges for removing stubborn residues and biohazardous substances from surfaces.
  • Steam cleaners for deep cleaning and sanitisation, penetrating porous surfaces to eliminate pathogens.
  • Scrub brushes and pads for detailed cleaning, especially in hard-to-reach areas and on textured surfaces.
  • High-efficiency particulate air (HEPA) vacuums to capture microscopic contaminants, including allergens, mould spores, and other airborne hazards.

Specialised Equipment

For specific biohazard situations, additional tools are used:

  • Biohazard waste containers for safe disposal of contaminated materials, ensuring they are handled and transported according to strict regulations.
  • Foggers and ozone machines to neutralise odours and sanitise the air, making environments safe and habitable again.
  • UV-C light devices for further disinfection of surfaces and air, using ultraviolet light to kill bacteria and viruses without the use of chemicals.Each piece of equipment and tool plays a crucial role in transforming a crime scene into a safe and clean environment.

Key Chemicals Used in Crime Scene Cleaning

Various chemicals are employed based on their specific roles in cleaning, deodorising, and disinfecting. Each chemical has its own unique mechanism of action, whether it’s attacking pathogens, dissolving residues, or purifying the air.

The careful selection of these chemicals ensures that the crime scene is not only visually clean but also microbiologically safe.


Byotrol is known for its antimicrobial properties, offering long-lasting protection against bacteria and viruses. It’s utilised in crime scene cleaning to ensure surfaces remain microbe-free for extended periods.

This powerful agent is a favourite among professionals because it provides a protective barrier that continues to work long after the initial application. This makes it an invaluable tool in the fight against cross-contamination and the spread of infectious diseases.


Chemspec products are renowned for their effectiveness in removing stains and odours. These solutions are crucial in addressing challenging cleaning needs at crime scenes, where appearances matter just as much as hygiene.

With Chemspec, cleaners can tackle everything from bloodstains to residual odours, restoring the scene to a neutral state that belies the chaos that once occurred there.

Other Common Chemicals

  • Enzymatic cleaners are essential for breaking down organic matter like blood and bodily fluids, transforming these potential biohazards into harmless substances that can be easily wiped away.
  • Hydrogen peroxide is a powerful disinfectant and bleaching agent. It is often used to eradicate stubborn stains and ensure all surfaces are pathogens-free.
  • Chlorine dioxide is used for its strong oxidising properties, which ensure thorough disinfection and eliminate any microscopic threats that could pose health risks.

    • The process begins with a comprehensive assessment of the crime scene to understand the extent and nature of the contamination.
    • Cleaners identify potential risks and hazards to ensure the safety of all involved.
    • Safety protocols are established, including the use of PPE like full-body suits, gloves, respirators, and safety goggles to protect cleaners from biohazards and chemicals.
    • The affected area is cordoned off to prevent unauthorised access and cross-contamination.
  2. Application of Chemicals and Cleaning Agents:

    • Following the safety setup, cleaners systematically apply specialised chemicals to affected surfaces.
    • Tools like mops, buckets, scrapers, sponges, steam cleaners, and scrub brushes are used to remove stubborn residues and deep-seated grime.
    • Enzymatic cleaners are applied to break down organic matter, such as blood and bodily fluids.
    • Hydrogen peroxide and chlorine dioxide are used because of their powerful disinfecting and bleaching properties, ensuring thorough sanitation of the area.
  3. Detailed Cleaning and Sanitisation:

    • The focus shifts to detailed cleaning, ensuring every corner and hidden spot is addressed.
    • HEPA vacuums are employed to capture microscopic contaminants and ensure air quality.
    • Specialised equipment, such as foggers and ozone machines, may be used to neutralise odours and further sanitise the air and surfaces.
