I worked in the food industry for years. Cleaning up at the end of the day ,of course,was the worst. Now bear with me,once these things get smaller,portable and affordable... imagine cleaning up with a spray bottle that uses light instead of chemicals. Laugh if you want to just remember phones used to be wired to your wall just 30/40 years ago....
Pressure washer will do it faster but also damages the wood more and more evrytime u pressure wash. Wood splitting chipping and any sealant will come off over numerous washes. Same goes for stone and concrete. Over time it will chip away and if there is a weak spot somewhere in the stone the pressure washer will definitely find it. Laser takes off the top surface with no pressure applied at all. No chemicals no damage to the wood.
