  Only when it looks like we have a bad mold or fungus contamination.

  What we've been told to do is wash all shelves, walls, etc. with soap and
water and then with bleach.  Then you need to autoclave anything that can be 
taken out, twice.

  We hire a company to formaldehyde treat the incubators.  Basically, they 
  seal off our tissue culture room, make everyone leave the lab, and turn on an
electric skillet full of formaldehyde.  They leave, come back several hours
later, and clean up.  The next day we wash down the sides and restart it. 
Works fairly well but is a pain to deal with.  My advisor says it's the only
way to kill spores, though.  Maybe she's wrong ?? :-)
