Can you test a Superscale economy injector on air?

If you do have some stubborn deposits that the vinegar does not remove, take some stranded copper wire and strip a small section of insulation off. Use the wire as a brush with the vinegar. Barry had told me to do that with a safety valve a few years ago.
