DIffuser cleaning

In our pharmacy we only clean the diffuser (the grill that is in front of the HEPA filter) in HLAFW every six months when the difusser is removed from the back of the hood for testing and maintenance.  However, I have been told that we need to start cleaning the diffuser every day as a part of daily cleaning after we clean the top.  Is this correct?  Anybody else is cleaning the diffuser multiple times throughout the day or even daily?
