Abstract: An embodiment provides a method for cleaning a surface, including: encapsulating a cleaning composition in a polymer material to form a compound, wherein the polymer material surrounds the cleaning composition; placing the compound in a location adjacent to the surface, wherein the location adjacent to the surface is a volume separated from an outer volume; dissolving the polymer material at a pH above a target value above the polymer material pH dissolution point, wherein the dissolving releases the cleaning composition; and cleaning the surface using the released cleaning composition. Other aspects are described and claimed.
