Anyone had to deal with concrete that has small stones imbedded into it? Either as a walk or on a wall? Any problems dislodging the stones or are they fairly durable to withstand Pressure Washing?
If they are done right, there is no problem. Just clean as you normally would. You will notice that it is "dirtier" than normal. There are a lot more grooves and such for dirt to be trapped in.
Michael,
not a dumb question at all, you shouldn't have a problem with it, just clean it like a normal concrete pathway etc, as always dont use any more pressure than is needed, a lot of pool aprons around here are poured that way!

I did a driveway yesterday and had no problems. It was concrete with 1/2 t0 3/4 river rock floated into it. I used Lowe's degreaser as it's fairly mild. I had a 3500 PSI 4 GPM cold water unit and .40 nozzle. The drive was about 20 years old and was subject to AZ sun almost constant. If yours is in cold country, I would check to see if any salt damage has occured. Good Luck.
