Dear Fab Network,<br><br>I am working on a cleaning plan for Penn's new cleanroom (about 10,000 sqft of class 100 and 1,000) and I am writing to ask for your help:<br>- Who does the cleaning for you: fab staff, central Facilities, external contractor, etc?<br>- How many times a day is your Facility cleaned?<br>- How often are the walls cleaned?<br>- How many "general cleanings" do you have throughout the year? Who does it?<br>- Do you use anything else besides DI water/IPA to mop the floors?<br>- If you do not have central vacuum, what vacuum cleaners have you had good experiences with?<br>- What precautions should one take when cleaning raised floors?<br><br>Thank you very much for your help.<br><br>Iulian<br>-- iulian Codreanu, Ph.D.<br>Director, Penn NanoFab<br>200 South 33rd Street<br>Room 376 GRW Bldg<br>Philadelphia, PA 19104-6314<br>P: 215-898-9308<br>F: 215-573-2068<br><a href="http://www.seas.upenn.edu/~nanofab"
