On completion of installation, thoroughly clean the surface by spraying an acidic or slightly alkaline pH
detergent, specific for quartz-resin agglomerates, on the surface, distributing it evenly with a soft sponge. Leave it for 5 minutes and then rinse with water until the detergent is completely removed. Remove any
excess water with a cloth and dry. The materials containing mother of pearl should not be washed with acidic cleaners
