macro that deletes certain results

I am making a macro that deletes #N/A's, but i want to add a few things to it
that should be deleted:

the phrases "total board", "total metal" and "Item", and any non-text (i.e. any
number) that appears.

this is what i have so far:

Public Sub DeleteStuff()
  Cells.SpecialCells(xlCellTypeFormulas, xlErrors).Delete
End Sub

what do i add to meet my specifications? Any help is greatly appreciated.
