Significance and Use

Cleaning of masonry, concrete, and stucco surfaces is undertaken for a variety of reasons including aesthetic improvement, removal of contaminants, maintenance, and surface preparation. This guide provides for selecting, testing, and evaluating cleaning techniques for removal of soiling and staining.

Cleaning systems may adversely affect both building materials being cleaned as well as other materials, mechanical, electrical, and other building systems, and building exterior, interior, and site features.

In some situations, it may be prudent to spot clean or to not clean.

It should be noted that, in some cases, cleaning may be inconsistent with the goals of historic preservation.
