Washing Landscape Stones
"We had landscaping stones embedded in the ground all around our shed. I dug them up to be used around a new fountain we were installing. Several high powered washes with the hose didn't touch the deep dirt. They looked pretty bad.
We've used Stain Solver on our decks and house siding with great success, so I tried soaking the stones in batches with Stain Solver in a large shallow plastic tub. I did do a light scrub over with a deck brush, once or twice while soaking. The stones came out brilliant and looking great! Perfect accent to our new fountain."
