Use at full strength with any type of pressure sprayer. Note that spray nozzles should be plastic or 316 stainless steel as this product will eventually corrode any other metal. Avoid over-spray or drift as non-target vegetation may be affected.

Dilute one part to 60 parts water. Once diluted, spray directly onto surface. Allow to stand for 15 minutes. Scrub surface with a sponge, cloth or brush as necessary to remove buildup and stains. Rinse thoroughly with water.
