Cleaning and Maintenance Guide of Sherwin-Williams Silicone Modified Polyester Coatings

Silicone modified polyester coatings are resistant to many elements found in the environment such as air pollution, acid rain, and general airborne dirt. However, if the need to clean or remove deposits from your coating does arise, a variety of methods for removal of surface deposits are available.

Group A: Hot or Cold Detergent Solutions

A 5% solution in water of commonly used commercial (non-industrial detergents will not have any deleterious effect on a paint surface. These solutions should be followed by an adequate rinse of water. Use a cloth or a soft brush for application.
