Though factory applied prepainted finishes are very durable and will last many years, eventually it may be desirable to thor-

oughly clean or repaint them.

Dirt pickup may cause apparent discoloration of the paint when it has been exposed in some dirt laded atmospheres for long

periods of time. In areas of strong sunlight, slight chalking may cause some change in appearance. A good cleaning will often

restore the appearance of these buildings and render repainting unnecessary. An occasional light cleaning will help maintain a

good appearance.

In many cases, simply washing the building with plain water using a hose or pressure sprayer will be adequate. In areas

where heavy dirt deposits dull the surface, a cloth or soft bristle brush and solution of water and detergent (

cup of laundry

detergent per gallon of water for example) may be used. This should be followed by an adequate rinse of water. Do not use

wire brushes, abrasives, or cleaning tools which will abrade the coating surface.

Mildew may occur in areas subject to high humidity but is not normally a problem due to the high inherent mildew resistance

of the baked finish that is used. However, mildew can grow on dirt and spore deposits in some cases. To remove mildew

along with the dirt, the following solution is recommended.

cup detergent (Tide

or equivalent)

cup trisodium phosphate (Solex

or equivalent)

1 quart of 5% sodium hypochlorite solution (Clorox

or equivalent)

3 quarts of water

Strong solvents and abrasive type cleaners should be avoided. Most organic solvents are flammable and toxic, and must be

handled accordingly. When using a solvent, consult maintenance professionals and label instructions for proper handling

and disposal of washings. If required, a mild solvent such as mineral spirits can be used to remove caulking compounds, oil,

grease, tars, wax, and similar substances. Use a cloth dampened with mineral spirits and apply only to areas which are con-

taminated. Follow up the use of this mild solvent with detergent cleaning and rinsing.
