How to Become a Crime Scene Cleaner?

The path to becoming a crime scene cleaner is not your typical 9-to-5 career trajectory. It's a profession that deals with the aftermath of some of life’s most challenging moments, and it requires a unique combination of skills, training, and temperament. In this blog, we’ll break down exactly how to become a crime scene cleaner, the qualifications required, and what the job entails.

Understanding the Job Role

Before we dive into the specifics of how to become a crime scene cleaner, it's crucial to grasp what the job involves. 

Crime scene cleaners are responsible for cleaning up and sanitising areas where violent crimes, accidents, or unattended deaths have occurred. 

This could mean dealing with blood, bodily fluids, and other biohazards. It's not a job for the faint-hearted, but it provides an essential service to families and communities during their most challenging times.

Necessary Qualifications and Training:

To become a crime scene cleaner, formal education is not strictly required. However, thorough training is mandatory. 

Companies like Causeway Cleaning emphasise the significance of rigorous training sessions for their staff to ensure top-tier service. This training often includes:

Biohazard Cleanup Training

This is about handling risky stuff safely. Think blood and other harmful materials often found at crime scenes. Cleaners learn how to deal with them safely, focusing on dangerous infections they can catch if not careful. Causeway Cleaning’s  training program encompasses various crucial aspects of biohazard cleanup, aligning with the stringent Health and Safety Executive (HSE) regulations.

Chemical Disposal

Cleaning a crime scene often means using strong chemicals. Cleaners need to know which ones to use, how to use them, and how to throw them away without harming the environment.

Personal Protective Equipment (PPE) Training

Safety first! PPE is the gear cleaners wear to protect themselves, like gloves and masks. It's not just about wearing them; it's about using them right. Training teaches cleaners how to wear and dispose of this gear properly.

Regulation and Compliance

Cleaning crime scenes also means following the rules. Different places have different rules about how to clean and throw things away. Training makes sure cleaners know these rules and stick to them. This keeps everyone out of trouble and ensures the job's done right.

Develop a Strong Mental and Emotional Resilience

Given the nature of the job, understanding how to become a crime scene cleaner is not just about the technical skills. Mental and emotional resilience is important. 

You might find yourself working in highly distressing environments, and being able to cope, staying professional, and offering compassion to the affected parties is essential.

Such situations demand more than just the technical side of things; they require an ability to detach oneself from the emotional weight of the scene while still maintaining a deep sense of empathy. It's a fine balance between ensuring that the job is done efficiently without being consumed by the gravity of the situation.

Physical Fitness

Engaging in the task of crime scene cleaning is no small feat; it's a physically taxing job that can take a toll if one is not prepared. Imagine moving heavy machinery or tools from one scene to another or stooping in certain positions to ensure every nook and cranny is cleaned. 

You may find yourself standing for prolonged periods or navigating cramped spaces. This is why maintaining good physical health is imperative. 

Regular exercise, cardiovascular training, and strength-building can go a long way in preparing you for the rigours of the job. It’s not just about stamina; it’s about ensuring you can perform optimally and safely in various challenging conditions.

Starting Your Journey

One way to start your journey on how to become a crime scene cleaner is by joining a reputable cleaning company like Causeway Cleaning. Being part of a renowned company offers a plethora of benefits: from hands-on training modules led by experienced professionals to understanding the intricacies of client relationships. 

Also, working with a reputable firm provides an atmosphere of mentorship, where learning from seasoned professionals can be a daily occurrence. This real-world exposure to various cleaning scenarios is invaluable for budding crime scene cleaners.

Continuous Learning

The field of crime scene cleaning is ever-evolving. Every year, there are new techniques, upgraded equipment, and innovative chemicals designed to make the process more efficient. 

Being complacent in this ever-evolving field is not an option. Whether it's attending workshops, reading industry journals, or undergoing advanced training sessions, an insatiable thirst for knowledge will ensure you remain at the forefront of your profession.


Building professional relationships is a cornerstone for growth in many fields, and crime scene cleaning is no exception. Engaging with peers, attending industry-specific seminars, or becoming a member of crime scene cleaning associations can offer an array of benefits. 

Not only can you share and gain knowledge, but such platforms can also provide job opportunities, partnerships, or collaborative projects. Building a robust professional network will undoubtedly serve you well in the long run.


As with many professions, there are subfields within crime scene cleaning. For instance, some might specialise in hoarding scenarios, meth lab cleanups, or mould and odour removal. 

Similarly, the nuances of mould and odour removal are distinct from standard crime scene cleanups. Recognizing your aptitude and passion for a particular niche can pave the way for specialisation, allowing you to cater to specific needs with expertise and precision. 

This not only positions you as an expert in that area but can also lead to more lucrative opportunities.

The Holistic Approach to Crime Scene Cleaning

Learning how to become a crime scene cleaner is more than just mastering the cleaning techniques. It's about being prepared mentally, emotionally, and physically for the demands of the job. 

And always remember, whether it's a traumatic crime scene or just a need for professional disinfection, teams like Causeway Cleaning are there to ensure spaces are returned to normal, providing peace of mind to those affected.

So, if you’re considering this path, know that it's a valuable service that brings solace and safety back into people's lives. With the right training, mindset, and dedication, you can excel in this unique and essential field.
