Take a polyester cleanroom wipe and hold it by its edges as shown
Fold the wiper in half
Fold the wiper in half again as shown
Apply cleaning detergent or solvent to the wiper. Ensure that wiper
and wash bottle do not come into contact with each other. This will
minimise cross contamination of solvent.
Start the cleaning action by bringing down wiper onto surface to
be cleaned with the front of the wiper held upward as shown and
the whole part of the hand pressing down firmly in a parallel orientation
to the wiper.
Wipe across the surface of the item to be cleaned in a positive
motion. At the end of the wipe, lift the wiper away from the surface
as shown with the back end of the hand lifting off the surface last.
Turn the wiper around so that a "clean" face is facing
the item to be cleaned and wipe accros the next section of un-wiped
surface as was done previously.
Once both sides of wiper has been used turn the wiper over so that
both the "dirty" sides face each other and clean the next
bit of un-cleaned surface as per above instructions.
Follow the same procedure as above points wiping across surface
in a positive manner.
Once you have done wiping twice each side, replace wiper with a
new one and follow the procedures as described above. The important
thing to remember is that the wiping action must be done in straight
lines across surface to be cleaned and not in circular motions.
At the end of each wipe lift wiper off the surface completely and
only wipe across surface twice with each side of wiper (8 wipe actions
Wipe across surface as per instructions above and lift wiper cleanly
away from surface at end of wipe. Turn the wiper around so that
the clean face is now facing the surface to be cleaned and redo
the actions specified above.
While wiping a surface try to view the surface at a 5° to 10°
angle with a dark back ground if it is possible. If you see any
particles on the surface then repeat above procedure.
