Currently, there are many sectors—such as industry, medicine, and cosmetics—where it is necessary to control contamination within a room to avoid altering product quality or causing potential infections. Therefore, cleanroom cleaning is essential.

A cleanroom, clean or sterile room is an enclosed space designed to maintain zero or extremely low levels of contamination. Its design is perfectly adapted to the specific requirements of the space and includes all necessary measures to prevent contamination:

• Interior finishes: rounded corners to prevent dust accumulation.
• Air particle control: air is filtered and renewed to prevent particle buildup.
• Pressure control: the room’s internal pressure is slightly higher to prevent microorganisms from entering from outside.

To maintain cleanroom purity, it is essential to rely on a specialized cleaning company experienced in this type of environment.

To maintain near-zero contamination levels, specific cleaning and disinfection procedures must be carried out, and the correct protocols must be followed.

There are many elements to consider in cleanroom cleaning. Since it is a sterilized space, no cleaning product can be introduced unless it has passed prior controls. Additionally, each area of the room has different cleaning requirements.

The main goal is to prevent contamination in sterile areas, as it can lead to problems such as product quality loss, infections, and increased costs. Among other factors, the constant opening of cleanroom access doors is one of the primary causes of contamination.

Another hygiene measure to consider in cleanroom cleaning is clothing control. All cleaning staff entering a cleanroom must follow the clothing protocol. This protocol requires washing hands and wearing sterilized gloves, gown, and cap. Additionally, before entering the cleanroom, personnel must step on the contamination control mat, which captures dirt and dust particles carried on footwear or equipment wheels.

All cleaning tools must be exclusively used for the cleanroom, must not be stored inside it, and must be disinfected or sterilized before entry.

To clean cleanrooms, special products that meet the space’s requirements must be used. Each area requires a specific process. The most commonly used are:

• Special vacuum cleaners that purify the air while cleaning.
• Microfiber cloths and mops (avoiding other materials). Products must be new for each cleaning service.
• Disinfectants and other chemical products depending on the type of room.

Each cleanroom has its own cleaning protocol; however, there is a general standard for all:

• Enter the cleanroom without electronic devices.
• Dress in a specific order: cover shoes, put on cap, pants, and gown.
• Once inside, put on gloves and goggles, in that order.
• Clean from the cleanest area to the dirtiest.
• Clean from top to bottom.
• Step repeatedly on the adhesive mat before entering.
• Follow the specific cleaning protocol for the room.

Cleanroom cleaning is a highly specific process. In addition to following a set order, each area has different cleaning requirements.

• Ceiling: must be disinfected and cleaned carefully, paying special attention to rinsing to avoid leaving product residues.
• Lights: require specific cleaning with a special mop and glass cleaner. Interior cleaning follows the same process.
• Walls, doors, and windows: must be cleaned from top to bottom with a cloth dampened with a cleaning agent. Frames must also be considered.

To remove adhesive residues or persistent paint, it is essential to consult the product supplier to find the most appropriate solvents.

It is important to remember that a cleanroom is a space that, due to its various uses, must maintain zero contamination conditions. Therefore, its maintenance is extremely delicate and must be handled by professionals with the necessary expertise.
