Powerwashing a Bench

Over the years the dust and dirt accumulate on tombstones,  and especially rough surfaces, like this unique bench found up at Clinton Garfield Cemetery near Rolfe.   This is the only concrete tree style bench I have seen...a cousin to some of the other molded tree monuments found in area cemeteries.   Once you get set up with the powerwasher a bench this dirty will take about half an hour to thoroughly clean.
