Cleanroom floors can easily become contaminated over time as dust and other particulates settle. We recommend that facilities regularly follow a comprehensive process to clean floors. This process should include the following:
- Vacuuming the surface to remove any loose dirt and debris.
- Next, rinse the floor with deionized water and a certified cleansing solution to break up films or dried contaminants.
- Once the floor is dry, vacuum it again to remove every trace of debris disturbed during the mopping process.
- For larger cleanrooms, it’s important to change the water between rooms or every 15 square feet to reduce the risk of cross-contaminating separate spaces.
Companies should also implement preventative measures to reduce contamination in the first place. These steps include mats, air showers, and shoe covers that keep debris from reaching the cleanroom environment in the first place.
The floor isn’t the only surface that suffers from contamination. It’s just as important to wipe down work surfaces, gowning areas and benches, pass-thrus, walls, and windows. Vertical surfaces can capture contaminants circulated through the air and may also become contaminated at high touch points.
We recommend using wipes and sponges that are specifically designed for cleanroom applications. These cleaning tools have less breakable fibers and are much less likely to create debris. Lint-free 70% IPA wipes, in particular, present minimal risk of debris. HEPA filter hand dryers are also available.

Additional Cleanroom Maintenance
Keeping your cleanroom in spec should be one of your facility’s top priorities. Additional steps your team can take to ensure high-quality production and testing conditions include:
- Instituting a regular schedule of daily, weekly, and monthly cleaning tasks.
- Using polycarbonate shields when lubricating equipment that prevent the lubricant from contaminating the space.
- Maintaining positive-pressure airflow before, during, and after cleaning procedures.
- Keeping detailed records about acceptable margins of contamination and the cleanroom’s adherence to standards of cleanliness.
- Ensuring workers having the necessary gowns, gloves, shoe covers, and other shielding materials to reduce contamination during cleaning procedures.
- Create detailed plans and assign responsibility for each cleaning task so your cleanroom is never in violation of cleanliness standards.
