Great video, even though not translated. Shows the process well. However, I wonder about the lemon juice/detergent combo clogging up the mask when dry. If I wear a mask while sanding, tiny dust particles will clog it and force air to leak in around the edges. Would that be an issue here? Have also heard about use of betadine-iodine dilution being used as gargle and nasal spray. Might that work similarly on masks?
