Revision Date: October 04, 2010
Updated On: October 05, 2010
Editorial Change:
Interior architectural paints are often discolored by dirt and other soilant materials. This test method covers the relative ease and completeness of removal of a specific soilant from such a surface by scrubbing. The greater the ease of soil removal with a minimum of film erosion, the greater the useful service life is expected to be.

Results obtained by this test method do not necessarily correlate with all types of soilants.

Semigloss finishes generally require only the nonabrasive type cleaner for good soilant removal, whereas flat paints may require the abrasive type.
