Choosing cleanroom wipers

The right wiper depends on your cleanroom class, the surface and what you are removing.

TypeGood forThink about
Knitted polyesterTighter classes, low particle release, durableHigher cost per wiper
Nonwoven (cellulose and polyester blend)General wiping and absorbency at a lower costCheck border sealing and particle limits for your class
MicrofibreFine surface cleaning and opticsCheck compatibility with your solvents
ESD wipersCleaning near sensitive electronicsCheck surface resistance values
Pre-saturated (for example IPA)Ready to use and repeatableShelf life and storage conditions

Five questions to ask

  1. Which cleanroom class or standard do you work to?
  2. What are you wiping: surfaces, tools, equipment or optics?
  3. Which solvents or disinfectants will you use?
  4. Do you need ESD properties?
  5. How are they packed: single or double bagged, sterile or non-sterile?

Wipers with sealed or laser-cut borders shed fewer loose fibres than cut edges.
