It is always suggested to clean a small section at a time. Start from the top and work your way down to prevent dripping or streaking onto the
cleaned area.
Gently clean the siding with the soft brush or wet soft cloth in a side to side motion in the direction of the plank siding. If cleaning panel, direction
of the siding is up and down. Do not push soft brush or wet cloth too hard against product surface. Do not allow the soap and mildew cleaner to dry
on the siding (continually rinse the area until all of the cleaner has washed off of the siding). Any areas that have been missed may show up when the
siding has dried. Spot clean and rinse any missed areas as needed.
If your surface still looks dirty after washing methods for dust/dirt and oil/grease, the problem may be mildew. Mildew discoloration can resemble dirt.
Moisture is the most important single factor in the growth of mildew, which can lie dormant for years. For this reason, mildew discoloration is usually
found in damp, dark areas or during prolonged humid conditions. Follow all instructions and precautions that are outlined on the label of the mildew
cleaner and wear all protective equipment that is prescribed.
IMPORTANT!
Low pressure water spray, a soft bristle (nonmetal) brush is most suitable for cleaning fiber cement products. If using a pressure washer, care must be
taken to ensure that the water stream does not damage the surface of the siding. Using wide fan tips that are kept a minimum of 6 feet from the wall
and at pressures under 1500 psi will minimize the chance of damaging the siding.
Sand blasting can damage the fiber cement surface and is not recommended.
Acid washing can damage the fiber cement surface and is not recommended.
Note: Damage to siding arising from improper cleaning or maintenance may not be covered by the James Hardie warranty.
