How to Properly Handle Soiled Cleanroom Garments

Softwall-Gownroom.jpgThe last two weeks, we have been focusing on the steps of donning and doffing your cleanroom garments. Just as important is what to do with them once you’ve removed them. We will give a quick guide here.

First and foremost, you should be working with a cleanroom garment processor to launder and repair your garments. This company needs to understand your contamination and quality control to know whether it can provide you a service. You should inform the processor of the type of soil on your garments (include your MSDS); what kinds of repairs the company can make (like patching); the acceptable amount of permanent staining; and clearly defined damage that would require a completely new garment.

With a garment processor in place, let’s look at what you need to be careful of when wearing your garments. Overall, everyone should take care to:

  • Prevent garments from becoming overloaded with particulate, soil, and fiber
  • Keep garments free of punctures, tears, and excessive wear
  • Store all garments in a controlled environment between wearings
  • Follow proper donning and doffing protocol
  • Sufficiently change inventory to prevent unnecessary degradation


After the garments have been removed, they need to be inspected and sorted. First you need to inspect the garment for soil and damage. Areas collecting the most wear include the abdomen, elbows, forearms, crotch, and zippers. This inspection will dictate how to sort it for the processor.  You also want to segregate each product, like hood, coverall, boots, etc.

Once you have identified the condition of the garment pieces and separated them out, you will need to further separate the garments into the following categories:

  • Needs cleaning (can be used again)
  • Needs replacement (beyond repair)
  • Needs repair
  • Needs repair and cleaning
  • Needs special processing (stain removal)
  • Unserviceable customer owned product


Finally, garment containers should be covered and lined or you may use 100% polyester bags. It is acceptable to mix soiled garments in containers. It is NOT acceptable to mix boots and overshoes with frocks, coveralls, hoods, or facemasks.

Knowing how to properly separate garments and prepare them for pickup will help prevent accidental contamination. For questions regarding cleanrooms, validations, certification, or construction, contact Gerbig Engineering Company at888-628-0056 or

Basic Cleanroom Gowning Removal

Last week we showed you a video tutorial on basic gowning procedures for a class 100 (ISO 5) cleanroom or better.We got our information from expert Jan Eudy. She writes that to remove the gown, simply reverse the order of the donning steps. However, we think there is a little more to it, so we’ve created another video to show you how to remove your gown.

Our pictures came from Wikipedia again, which credits the information to anthillhopkin –

Basic Cleanroom Gowning Procedures

We love taking advice from Jan Eudy, who is a Cleanroom/Contamination Control Consultant, ISO 9000/cGMP auditor, and HACCP/Food Safety Auditor. She offers a step-by-step protocol for cleanroom gowning in Controlled Environments.

We used her model to create basic gowning procedures. We also found some great images on Wikipedia, which credits them to “Dorothyboyd –”

Putting them together, we created a short video to help you understand these steps for class 100 (ISO 5) cleanroom or better.
