CARE AND MAINTENANCE
GenStone Products are some of the most durable building products materials available today
for residential applications. In most cases, normal rainfall is sufcient to keep it clean. But if your
GenStone Products should need cleaning, we recommend the following procedures. Particular
attention should be given to areas under eaves, porches, awnings and other overhangs that have
limited exposure to the natural washing effect of rainfall.
1. Moderate Atmospheric Dirt: We recommend an occasional washing with clear water using a
garden hose and soft-bristled brush (a long-handled, car-washing brush is ideal for this purpose).
2. Heavy Industrial Atmospheric Dirt: Wash in the manner indicated above, but use the following
solution:
a. 1/3 cup detergent or 1/3 cup dish soap (Tide®, for example)
b. 2/3 cup trisodium phosphate (Soilmax or Dirtex, for example)
c. 1 gallon water
3. Mildew Accumulation: Mildew can collect on surfaces of all types of building
products and is often evident on surfaces that have not been properly cared for and
maintained. Normally, mildew will appear as black spots. Mildew is easy to remove
by using the basic cleaning solution above with the addition of sodium hypochlorite
as follows:
a. 1/3 cup detergent (Tide®, for example)
b. 2/3 cup trisodium phosphate (Soilax®, for example)
d. 1 gallon water
4. Caulking Compounds, Tar and Similar Substances: Use mineral spirits in reasonable amounts
and apply directly to the foreign substance. Immediately after cleaning, rinse the area thoroughly
with water.
