We recommend washing your tray before first use. Take care whilst washing, as even in water the surface can become scratched by other items. If washing by dishwasher, rinse to flush away deposits of detergent which may form a film if allowed to dry.
Do not use abrasive cleaning products or scourers. Tea and coffee stains can be removed using bicarbonate of soda, and silverware cleaner can be used to remove and marks caused by cutlery.
