This question is part of the following Ask The Expert session:
Often cabinets and incubators can be a source of contamination since these are often shared among multiple people/research groups. It is therefore important to have regular maintenance and cleaning of these. Incubators should be cleaned with Lysol and 70% EtOH once a month and shelves should be autoclaved. Clean water tray often (autoclaved, distilled water) and clean spills immediately. Daily cleaning of hood space with 70% EtOH, as well as monthly cleaning with 10% bleach or equivalent products is suggested.
