Behind The Yellow Tape: The Crime Scene Cleaning Process

When a criminal act leaves a traumatic scene behind, the response involves not just law enforcement and medical personnel, but also crime scene cleaners. These individuals play a crucial role in restoring the scene to a safe and livable state. The process involves a series of steps to ensure thorough cleaning.

Assessment and Planning

The first step in the crime scene cleaning process is a thorough assessment. This involves understanding the nature and extent of the incident and identifying potential biohazards such as blood, bodily fluids, or drug residue. From this evaluation, a detailed plan is drawn up outlining the necessary cleaning, decontamination, and restoration tasks.

Personal Protection

Before cleaning begins, crime scene cleaners must don appropriate personal protective equipment (PPE). This often includes biohazard suits, gloves, respirators, and eye protection. Given the potential exposure to harmful pathogens and hazardous substances, this step is vital for the safety of the cleaning personnel.

Removal of Biohazardous Materials

The next stage involves the removal of all visible biohazardous materials. This includes blood, tissues, bodily fluids, or other potentially infectious materials. These materials must be carefully collected and disposed of following local regulations for biohazardous waste.

Cleaning and Disinfecting

Cleaning and disinfecting is a comprehensive and meticulous process, carried out using industry-grade cleaning solutions and disinfectants that are designed to eliminate a wide range of pathogens.

The cleaners pay particular attention to the elimination of bloodborne pathogens such as HIV, hepatitis B, and hepatitis C, which might be present at the scene.

Moreover, the disinfection process goes beyond simple surface cleaning. Depending on the severity and nature of the crime scene, this step can include cleaning floors, walls, ceilings, and even hidden areas where biohazardous residues might have reached. It may also involve the cleaning of furniture and personal belongings.

In cases where these items are too contaminated to be cleaned, they will be safely disposed of. 

Odor Removal

Depending on the nature of the crime, unpleasant odors can often linger at the scene. Therefore, a crucial step in the process is odor removal. This can be achieved through the use of professional-grade deodorizers, ozone generators, or fogging equipment.


The final stage in the crime scene cleaning process is restoration. This may involve repairing physical damage to the property, replacing contaminated materials such as carpets or drywall, and repainting walls. The goal is to return the area to its original condition, making it safe and habitable once again.
