International Classification:

C11D 1/94
C11D 1/62
C11D 1/90
C11D 3/00
C11D 3/43
Abstract:

A composition is provided containing a pH adjuster, a surfactant, and a solvent, wherein the composition has the ability to solubilize MAAs that creates dark streaks on roof shingles. The method of making the composition involves mixing a pH adjuster and a surfactant with water. A method of using is provided in which additional water is added to the composition. Once the composition is diluted and the desired alkalinity is reached, the composition is sprayed on a roof through a device having a spray/stream end. The output from the spray/stream end of the device transforms secreted MAA present on the roof shingles into an orange color upon contact. The resulting orange residue is then rinsed off from the shingles to provide a new looking roof.
