<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The cleanroom at Birck is a bay-chase design with a central hallway. The bays are cleaned weekly using a microfiber mop system and UPW as the solvent. The chases are cleaned every two weeks using the same system
plus hand cleaning of piping, etc. using cleanroom wipes. 90/10 UPW & IPA is used to spot clean more stubborn contamination as needed. The central hallway floor is cleaned daily (M-F) using the microfiber mops. The wipes are disposable, but the microfiber
mops are laundered off-site.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The mop system I mentioned replaced a three step method we formerly used. The old procedure involved using a HEPA vac, followed by a wiper/paddle system with 90/10 UPW & IPA as the solvent, followed by a second
HEPA vacuuming. Both methods were approximately equal in their removal of contamination, but the microfiber system is faster since it involves only one step. That allowed us to reduce cleaning personnel by 1/3, which offset the increased cost of the microfiber
mop system. <o:p></o:p></span></p>
