What to Know About Cleanroom Cleaning Services in California

Operating a cleanroom requires a lot of planning and can be stressful enough without worrying about contamination caused by an inexperienced cleanroom cleaning services provider. This is why selecting a provider with expertise in cleanroom maintenance and cleaning is essential. With this in mind, below are some basic questions about cleanrooms and the answers that cleanroom cleaning services in California should know.

Q. Why do companies need cleanrooms?

A. Companies require cleanrooms to prevent contamination during the manufacturing process. Imagine the damage that dirt and debris could cause by infiltrating the manufacturing processes in defense aerospace facilities or pharmaceutical laboratories.

Q. Why is it important to keep cleanrooms clean?

A. Contamination in the manufacturing process can render products useless, unreliable, or dangerous.

Q. Why must supplies entering the cleanroom be wiped down?

A. All cleanroom cleaning products must be wiped down to reduce the chance of polluting the cleanroom environment with outside contaminants.

Q. How often do cleanrooms need to be cleaned?

A. How often a cleanroom needs to be cleaned can vary by industry, traffic, and class. Class 1 cleanrooms, with the highest level of required sanitation, will require cleaning more frequently than Class 9, which requires the lowest level of sanitation. Yet even Class 9 cleanrooms should be cleaned at least once daily.

Q. How do you disinfect a cleanroom?

A. Cleanrooms are disinfected in much the same way as other areas. However, only approved cleanroom cleaning products can be used. Isopropyl alcohol (isopropanol) is usually considered the best disinfectant to use, although a hydrogen peroxide-based disinfectant can also be used. Cleanroom cleaners must first clean surfaces with a detergent and wipe them with distilled water before applying a cleanroom-approved disinfectant.

Q. What are the major sources of cleanroom contamination?

A. This can vary by industry, but as an example, sources of cleanroom contamination in an aerospace cleanroom include:

  • People
  • Airflow
  • Fluids
  • Equipment
  • Contaminants entering from other parts of the facility
  • Raw materials and products
  • Processes, such as those used in manufacturing.

Q. What methods are used in the cleanroom to maintain cleanliness?

A. Again, specifics can vary, but the basic process cleanroom cleaning services in California should follow before each shift is to:

  • Damp-mop floors and vacuum them dry
  • Vacuum walls with a HEPA filter vacuum
  • Wash and wipe dry windows and pass-throughs.

At the end of each shift, all work areas should be wiped down, and all cleanroom cleaning products and other supplies should be put in their proper storage area.

Q. What is not allowed in a cleanroom?

A. Items that are not approved to be in a cleanroom are not allowed, including cleanroom cleaners’ personal items.
