This area can be a bit difficult to clean.  There are two different ways of achieving this. This would be for indoor locations.  #1 – A small broom that you can fit through the bars of the OV (center section).  #2 – use a push broom/dust mop to go from underneath.  For outdoor locations, use either broom, air blower, garden hose.
