removing controls from frame

[RAYLWARD102]

I have a frame that I'm able to create dynamic buttons into it with VBA code.
At times, I want to clear the slate (the frame to be exact) but have had some issues. I originally used:

userform1.frame1.clear

Which seemed to work fine until I moved my project to another computer.
I then changed it to

For Each ctl In Userform1.frame1.Controls
    ctl.Visible = False
Next ctl

Which works but I feel is not the correct way of handling the removal of controls.

How do I remove all controls from frame1.
Here is the code I used for creating the buttons.

For Each cell In spTY.Range("ak2:ak" & iRow).Cells
        If cell.Value = "" Then GoTo nextitem
            Set ctl = UserForm1.Frame1.Controls.Add("Forms.CommandButton.1")
            ctl.Caption = cell.Value
            ctl.Font.Size = 12  'SET FONT SIZE TO 14
            ctl.BackStyle = 1
            ctl.BackColor = &HFFC0C0
            ctl.TabStop = False

    
            If zx < 2 Then
                ctl.Left = zx * 125 'adjust the width if you adjust this left. example: width 120 then left is 130
                ctl.Top = zq * 26 'adjust the height if you adjust this top. example: height 30 then top is
            Else:
                zx = "0"
                zq = zq + 1
                ctl.Left = zx * 125
                ctl.Top = zq * 26
            End If
            ctl.Font.Name = "Arial"
            ctl.Font.Bold = True
            ctl.Height = 24 '25
            ctl.Width = 120 '110
            ctl.WordWrap = True
            
            ReDim Preserve CmdButtons1(1 To i + 1)
            Set CmdButtons1(i + 1).CmdGroup1 = ctl
            i = i + 1
            z = z + 130
            zx = zx + 1
nextitem:

    Next cell
