For tough stains use a stronger concentration of RC-1000.
Agitation may be required to remove some organic matter. A soft scrub brush or pressure washer set at 400 psi can be used to agitate tough stains.
Avoid RC-1000 over spraying on household windows, glass and automobiles. (It could cause a tough to remove residue)
Be sure to cover any landscaping plants or flowers to avoid being directly sprayed with RC-1000.
