If you customize PowerPoint with controls (button, text boxes, labels, etc.) you may want to delete or hide these to create a clean version of your presentation. Below is a script you can use hide all of the controls (or you can filter). My example uses PowerPoint 2010 but should apply to most recent versions:
1. Create a new module: 
2. Paste the below text:
Public Sub HideControls() 'keep a count of how many items hidden - just fyi Dim cntrlCount As Integer 'loop through slides For Each sld In ActivePresentation.Slides 'loop through slide shapes - includes button, text boxes, ole controls, etc For Each shp In sld.Shapes ''Filter here if you want - by name or type ' If InStr(shp.Name, "command") >= 1 Then ' If shp.Type = 3 Then 'set hidden shp.Visible = False 'if you wanted to delete*: shp.Delete cntrlCount = cntrlCount + 1 Next Next MsgBox cntrlCount & " items affected." End Sub
3. Click Run (green play button) to run this code and hide your controls. 
If you want to show or unhide your controls, change shp.Visible = False to shp.Visible = True
*Note: if you use shp.Delete, you won’t be able to recover your items.
