Cleaning and Maintenance Guide

Cleaning and Maintenance Guide for Metal Building Components Coated with Fluoropolymer Products: Bruce and Dana recommends clean water washing of roof 1-2 times per year.

Fluoropolymer systems are similar in molecular structure to Teflon, a product most of us are familiar with through use in our households. The molecules on the surface of the coating are so tightly bound together that they don't want to react with anything. Their slick surface helps make them resistant to many elements found in the environment such as air pollution, acid rain, and general airborne dirt.

Although factory applied finishes are extremely durable, a periodic cleaning to remove build-ups of resins and other residue is a good idea to extend coating life. A variety of methods for removal of surface deposits are available. Simple washing with plain water using hoses or pressure spray equipment is usually adequate. When surfaces are dulled by heavy deposits of dirt or other contaminants, stronger methods may be needed.

2 Precautions:

  1. Do not use wire brushes, abrasives, or similar cleaning tools which will mechanically abrade the coatings surface.
  2. Certain cleaning agents listed below should be tested in an inconspicuous area before use on a large scale.
GROUP A: Hot OR Cold Detergent Solutions
A 5% solution in water of commonly used commercial and industrial detergents will not have any deleterious effect on a fluoropolymer surface. These solutions should be followed by an adequate rinse of water. Use a cloth or sponge for application.
GROUP B: Solvents
Most Organic Solvents are flammable and/or toxic, and must be handled accordingly. Keep away from open flames/sparks/electrical motors. Use adequate ventilation, protective clothing and goggles.

Solvent that may be used to remove non-water soluble deposits (tar, grease, oil, paint, graffiti, etc.) from fluoropolymer surfaces include:
  • Alcohols.
  • Denatured Alcohol (ethanol).
  • Isopropyl (rubbing alcohol).
  • Methanol (wood alcohol) Note: Methanol is toxic.
The above alcohols have no permanent effect on fluoropolymer surfaces.
GROUP C: Petroleum Solvents and Turpentine
  • VM&P naphtha.
  • Mineral Spirits.
  • Kerosene.
  • Turpentine (wood or gum spirits).
The above solvents have no permanent effect of fluoropolymer surfaces.
