– Q. See question above. Can it be better doing the spraying with a “Shinui” or change from the normal usage? What would be a qualifying proper shinui?

A. Indeed it would be preferable when possible to spray with a Shinui. It may be that instead of pressing with ones finger on the spray button one could use the back of the hand or similar
