Sanitizing Hospital Masks: A Step-By-Step Guide

Keeping hospital masks clean is essential to maintaining a sterile environment and preventing the spread of harmful bacteria and viruses. With the ongoing COVID-19 pandemic and the increasing importance of infection control, it is crucial to understand the proper methods for disinfecting and sanitizing hospital masks to ensure the safety of patients, healthcare workers, and the general public. In this discussion, we will explore the various types of hospital masks, the potential risks associated with contaminated masks, and detailed step-by-step guides on how to effectively clean and maintain different types of masks used in hospital settings.

Wash with laundry detergent

When it comes to cleaning a hospital mask with laundry detergent, there are some important considerations to keep in mind. Firstly, it's crucial to distinguish between different types of masks, as their cleaning methods can vary. For instance, surgical masks are designed for single-use only and should not be washed and sanitized. Attempting to clean them can reduce their effectiveness in filtering bacteria. Similarly, N95/KN95 masks are not meant to be washed, as it will compromise their filtration efficiency.

For cloth masks, however, laundry detergent can be an effective cleaning solution. These masks can be washed with your regular laundry and detergent. It is recommended to use the warmest water setting that is suitable for the type of cloth. Even cold water can be used, as long as detergent is added. After washing, tumble dry the mask on high heat and ensure it is completely dry before wearing it again. Alternatively, you can handwash the mask with hot, soapy water. Scrub the mask for at least 20 seconds, then thoroughly rinse with clean water.

It is worth noting that there are potential risks associated with laundering healthcare-related items at home. Research suggests that domestic washing machines may not effectively kill harmful bacteria and pathogens, potentially spreading antibiotic-resistant bacteria. Therefore, it is crucial to adhere strictly to guidelines, such as using appropriate temperatures, detergents, and disinfection methods, to minimize risks.

Additionally, when laundering a hospital mask, it is important to follow facility-specified procedures for PPE, especially in hospital and institutional settings. Universal precautions should be taken, and items should be placed in an impermeable, labelled laundry bag. The recommended detergent and warmest appropriate water setting for the items should be used. Prior to disinfecting, a cleaning step should be performed to remove visible soil, bodily fluids, and other contaminants.

Handwashing with bleach

Bleach is a powerful cleaning agent that contains a range of chemicals. When using bleach, it is important to protect yourself with the necessary personal protective equipment (PPE). This includes wearing gloves, a gown, and an R95-rated respiratory mask with carbon filters. The carbon filters in the mask absorb fumes, preventing them from entering your airways and potentially damaging your organs. Goggles or a face shield can also be worn for additional protection.

Before handling bleach, make sure the area is well-ventilated. If you accidentally inhale bleach fumes, remove yourself from the area, get fresh air, loosen your clothing, and allow time for any irritation or symptoms to pass. Symptoms of bleach inhalation may include watery eyes and a burning sensation in the nose, throat, and lungs. If symptoms persist after a few hours, seek medical attention.

To clean a hospital mask with bleach, create a bleach solution by mixing one quart of room-temperature water with four teaspoons of bleach. Soak the mask in the solution for about five minutes. Then, thoroughly rinse the mask with water and lay it flat to dry. If possible, place the mask in direct sunlight, as UV light can help kill any remaining germs.

It is recommended to have more than one mask so that you can wash each one after every use. The CDC advises washing cloth face masks after each use, especially if they come into contact with bodily fluids such as sweat, mucus, or vomit. Regular washing helps prevent the spread of infections and keeps your mask clean and hygienic.

Air drying

Firstly, it is important to note that masks should never be placed in a dryer, as the heat will ruin the elastic. Instead, masks should be left to air dry. To do this, place the mask on a clean surface and leave it until it is completely dry. This will ensure that no water spots are left on the mask. It is important to use soft materials to dry your mask if you wish to speed up the process.

Additionally, it is recommended to avoid direct sunlight when air-drying your mask, as discolouration may occur. Instead, opt for a well-ventilated area out of direct sunlight.

It is also important to note that masks should be completely dry before storing them. Masks can be stored in a clean container, bag, or separate drawer. Hanging your mask on a hook is also an option, but be cautious of the loops stretching out, which can cause an improper fit.

Finally, it is recommended to wash or sanitise your hands before and after touching or removing your mask. This will help prevent the spread of contaminants and ensure the mask stays clean.

Rinse with freshwater

Rinsing your hospital mask with freshwater is a simple and effective way to keep it clean and hygienic. This method is suitable for scuba diving masks and snorkels, which should be rinsed with freshwater after each use, even after being used in freshwater.

Freshwater sources such as lakes can contain algae, minerals, and other substances that can adhere to your mask. Therefore, rinsing your mask with freshwater after diving is essential to remove any built-up residue. A good soak in freshwater will help eliminate smaller sediments that may have accumulated during use.

Rinsing with freshwater is a gentle yet effective method to maintain your hospital mask. It helps to wash away any dirt, debris, or impurities that may have come into contact with the mask. Freshwater is a natural solvent that can loosen and dissolve particles, ensuring a thorough rinse.

Additionally, freshwater rinsing can help prevent the buildup of odours and maintain the clarity of the mask. It is a simple and quick way to care for your hospital mask and ensure it remains in good condition.

Overall, rinsing with freshwater is a vital step in the cleaning process of a hospital mask. It helps to remove contaminants and keep the mask fresh, clear, and ready for use. This method is simple, accessible, and effective, making it a convenient choice for maintaining the hygiene of your hospital mask.

Soak in vinegar

Vinegar is a natural antiseptic that can effectively kill harmful bacteria, viruses, and other microorganisms that can build up on your hospital mask. The acidic nature of vinegar also helps to dissolve the buildup of oils and other substances that can cause skin irritation or rashes. Using distilled white vinegar to clean and sanitize your hospital mask is a cost-effective and natural way to keep your equipment clean and free of harmful bacteria and other microorganisms.

To use vinegar to clean your hospital mask, first, prepare a solution by mixing equal parts of distilled white vinegar and water in a basin. It is important to use the correct dilution ratio and not soak the mask for too long, as soaking for an extended period of time or using too strong of a vinegar solution can damage the materials used in the mask. Be careful not to soak any electrical components in the vinegar solution and avoid getting vinegar into the mask frame.

After preparing the solution, disassemble the mask and soak the components in the solution for 15-30 minutes. The cushion and headgear can be soaked in the solution, but be sure to avoid any electrical components or the mask frame. Following the soak, be sure to rinse the mask components with clean water and allow them to air dry completely before using the mask again.

In addition to soaking the mask components in vinegar, you can also use vinegar to clean the water tank or humidifier chamber of your hospital mask. If you find mineral buildup on the metal plate, soak the chamber with white vinegar and warm water at a ratio of 1:10. This will help to remove any buildup and keep your equipment clean and well-maintained.
