Cleanroom wiping is not a complex procedure; however, a few guidelines should be followed for optimal effectiveness. Following the steps below ensures effective cleaning and avoids redistribution of surface contamination. Always follow protocols for your cleanroom.
Quarterfold the wiper by folding it in half once and then again.
Moisten the wiper with a compatible cleaning solution either in the bag or with a squirt bottle.
Take your first pass wiping the surface from cleanest to dirtiest, methodically in a linear stroke.
Flip the wiper to the clean side and make a second pass, overlapping the previous pass slightly.
Partially unfold the wiper to expose additional clean wiper surfaces.
Take two additional passes, methodically working your way across the surface using a clean side of the wiper for each pass.
Remember to only make one pass with each wiper side. Take a systematic approach, keeping track of where you have wiped. Once all 4 sides of the wiper have been used, it may be unfolded and reversed so that four additional clean sides are available. When all surfaces of a wiper have been used, dispose of the wiper.
