I am using the following code to delete a row in a spreadsheet based
on the value (zero) in that row:

Sub RemoveZero()
Dim RngColAB As Range
Dim c As Long
Application.ScreenUpdating = False
Set RngColAB = Range("AB2", Range("AB" & Rows.Count).End(xlUp))
For c = RngColAB.Count To 1 Step -1
RngColAB(c).Value = Application.Trim(RngColAB(c))
If RngColAB(c).Value = 0 Then _
RngColAB(c).EntireRow.Delete
Next c
Application.ScreenUpdating = True
End Sub

How can I modify it so that it looks to two columns where both rows
have to have a zero value so that the row can be deleted?
