Common Mistakes When Disinfecting and How to Avoid Them

Disinfecting is a critical step in maintaining hygiene and preventing the spread of infections, particularly in healthcare, food production, and public spaces. However, improper disinfection practices can significantly reduce the effectiveness of the process, leaving surfaces inadequately sanitised. Understanding the common mistakes people make when disinfecting and learning how to avoid them can lead to safer, cleaner environments.

Not Cleaning Before Disinfecting

One of the most frequent errors is skipping the cleaning step before disinfecting a surface. Many believe that applying a disinfectant on a dirty surface will automatically kill all germs. However, dirt, grease, and organic matter can act as a barrier, preventing the disinfectant from reaching and eliminating pathogens. This is particularly important in healthcare or food processing environments, where biofilm can form on surfaces, harbouring bacteria and reducing disinfectant efficacy.

To ensure that disinfection is effective, always clean surfaces with soap and water or a general-purpose cleaner to remove visible debris. Once the surface is cleaned, apply the disinfectant as recommended. This two-step process will result in better hygiene outcomes and a higher level of infection control.

Using the Wrong Disinfectant for the Job

Another common mistake is using the wrong type of disinfectant for the surface or pathogens you are trying to eliminate. Disinfectants are not universally effective against all types of microorganisms. Some may target bacteria but be ineffective against viruses or fungi. For example, healthcare settings may need disinfectants that kill antibiotic-resistant bacteria, while food industries require solutions that ensure safety without leaving harmful residues.

Choosing the appropriate disinfectant requires understanding the specific pathogens in the environment and selecting a product formulated to combat them. Reading product labels for efficacy data and consulting manufacturers can help in selecting the most appropriate disinfectant for your needs. 

Incorrect Dilution of Disinfectant

Disinfectants are often sold in concentrated forms, requiring proper dilution to work effectively. Incorrectly diluting a disinfectant, whether too strong or too weak, can have negative consequences. A highly concentrated solution may damage surfaces, release harmful fumes, or cause skin irritation. Conversely, an overly diluted disinfectant will not be potent enough to kill pathogens effectively.

To avoid these issues, follow the manufacturer's instructions carefully for the correct dilution ratio. Use measuring tools to ensure accurate mixing, and avoid estimating amounts, which could lead to under- or over-concentration.

Inadequate Contact Time

Contact time is a critical factor in ensuring the effectiveness of a disinfectant. Each product requires a specific amount of time to remain wet on a surface to properly kill microorganisms. Wiping off the disinfectant too soon or allowing it to dry prematurely may result in incomplete disinfection, leaving harmful pathogens behind.

To avoid this, ensure that surfaces remain wet with the disinfectant for the full contact time as specified by the product label. For example, some disinfectants may require a contact time of 5-10 minutes to achieve full efficacy. Adjusting your cleaning procedures to allow for this time will ensure optimal results.

Using Expired Products

Like most chemical products, disinfectants have a shelf life, after which they may lose their potency. Using expired disinfectants can reduce their effectiveness, rendering them incapable of eliminating pathogens effectively. Unfortunately, expired products are sometimes overlooked, especially in large organisations with multiple cleaning supplies.

To avoid using expired disinfectants, establish a routine for checking expiration dates and replacing outdated products. Proper storage, such as keeping disinfectants in cool, dry areas, will also help maintain their potency over time. Additionally, stock rotation practices, like using older products first, can prevent the unintentional use of expired items.

Overlooking High-Touch Areas

Even with the best disinfection protocols, high-touch surfaces can sometimes be neglected. Areas such as door handles, light switches, elevator buttons, and keyboards are often touched by multiple individuals throughout the day, making them hotspots for pathogen transmission. Failing to disinfect these areas frequently enough can increase the risk of spreading infections.

To avoid overlooking these critical areas, implement a disinfection schedule that prioritises high-touch surfaces. Assign specific responsibilities to staff members to ensure that these areas are regularly disinfected, and consider using checklists or automated reminders to maintain consistency.
