Tip #3 – Proper Cleaning Techniques

Is refolding a wiper recommended cleanroom protocol for surface cleaning?

“Refolding the wiper can reduce wiper usage but requires operators to keep track of which wiper surfaces have been used for cleaning. Refolding a wiper should be avoided if the surface being wiped is wet or very dirty and there’s a good chance that the contamination would transfer throughout the wiper. This is most likely to occur if one is picking up a dirty spill.”¹

So yes in most cases ¼ folding is recommended as it provides maximum wiper usage and surface cleaning efficiency since a ¼ folded wipe offers 8 separate clean sides.

Tip #3 – Proper Cleaning Techniques: ¼ folding the wipe to offer 8 separate clean sides is recommended except in a case where the surface is very wet or very dirty as the contamination could transfer throughout the wiper.
