Karran 8 oz. Luster Pro Quartz Sink Cleaner is a specialized maintenance solution designed to protect, restore, and enhance the appearance of quartz and granite composite kitchen sinks. The food-grade mineral oil formula creates a protective hydrophobic coating that helps repel water, reduce lime scale buildup, and minimize water spotting. Regular application restores the sink’s natural luster while helping maintain the rich color and smooth finish of quartz surfaces.

Ideal for routine sink maintenance, Luster Pro Oil spreads easily and absorbs quickly when applied with a clean cloth after normal cleaning. The treatment helps prevent residue buildup and keeps composite sinks looking clean and vibrant with minimal effort.
