Dependent upon the finish coating used, in most cases normal rainfall consistent with local average rainfall is sufficient to keep Ply Gem Elements Composite Siding clean. But if your Ply Gem Elements Composite Siding should need cleaning, we recommend the following procedures (particular attention should be given to areas that have limited exposure to the natural washing effect of rainfall):
- 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).
- Heavy Industrial Atmospheric Dirt
- Wash in the manner indicated above, but use the following solution:
- 1/3 cup detergent (e.g., Tide®)
- 2/3 cup trisodium phosphate (e.g., Soilax®)
- 1 gallon water
- Wash in the manner indicated above, but use the following solution:
- 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 following solution:
- 1/3 cup detergent (e.g., Tide®)
- 2/3 cup trisodium phosphate (e.g., Soilax®)
- 1 quart sodium hypochlorite 5% solution (e.g., Clorox®)
- 3 quarts water
- 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 following solution:
- Caulking Compounds, Tar and Similar Substances
- Consult the manufacturer of the caulking compounds and/or other sealants used to determine the best cleaning solution.
TIPS:
- Where the house is extremely dirty, it is recommended you start washing from the bottom and go to the top, rinsing frequently. Cleaning solutions should be permitted to stand on the surface of the siding for several minutes before rinsing.
- Pay particular attention to areas under eaves, porches, awnings, and other overhangs that have limited exposure to the natural washing effect of rainfall.
CAUTION:
Do not exceed the recommended concentrations of cleaners; to do so can cause damage to the product. Avoid skin and eye contact with the solution, and in all cases follow the manufacturer’s instructions for the use of cleaning compounds and solutions. Avoid use of abrasive-type cleaners and strong solvents. Test any cleaner on an inconspicuous area before applying to major areas. To minimize streaking, always clean from the bottom to the top and follow with a rinsing of clear water. Excessive scrubbing is unnecessary, can be harmful to the products, and may cause undesirable glossy areas over the finish.
Do not use or mix sodium hypochlorite with other household chemicals or products containing ammonia. To do so will release hazardous gases.
Use care not to saturate window and door openings when cleaning your Ply Gem Elements Composite Siding.
