I need to create a reset button that will reset rows containing a specific value

I really need help with this guys... let me explain in a better way...

This code does exactly what I want:

Private Sub CommandButton1_Click()

If Range("F21").Value = "Hospedado" Then
Range("F21", "X21").Value = ""
End If

End Sub

That's only for the first row F. I have another 150 rows that need the same coding. So this works as well:

Private Sub CommandButton1_Click()

If Range("F21").Value = "Hospedado" Then
Range("F21", "X21").Value = ""
End If

If Range("F22").Value = "Hospedado" Then
Range("F22", "X22").Value = ""
End If

If Range("F23").Value = "Hospedado" Then
Range("F23", "X23").Value = ""
End If

End Sub

And so on... if I continue with this code 150 times down I have solved my problem, however, there must be a simpler way to do it? I've tried this and it does NOT work...

Private Sub CommandButton1_Click()

If Range("F21":"F170").Value = "Hospedado" Then
Range("F21", "X170").Value = ""
End If

End Sub

Any ideas?

Thanks and regards,
