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.
Claims8
A method for cleaning a sleeve of an ultraviolet light source, comprising:
- providing the ultraviolet light source for disinfection of a fluid, wherein the sleeve surrounds the ultraviolet light source;
- encapsulating a cleaning composition in a polymer material to form a compound;
- placing the compound in a location adjacent to the sleeve, wherein a canister around and in contact with the sleeve encapsulates the compound against the sleeve;
- dissolving the polymer material at a pH above a polymer material pH dissolution point, wherein the dissolving releases the cleaning composition;
- and
- cleaning the sleeve using the released cleaning composition.
