Sonic Cleaner for Concrete Garden Slabs
I use a pressure water jet to clean concrete garden slabs. For reference, I used 80 gallons of water and the project took six hours. I cannot imagine how much electricity was used. I believe that technology exists to manufacture a sonic cleaner similar to a portable metal detector. If this could be achieved, then world wide savings in water, electricity, and labor hours could be very significant.
