Ice trays picking up freezer odors? Check the lid and cleaning label
Lidded ice trays can help limit freezer odors. Follow the model-specific dishwasher or handwashing label, clean the tray and lid, dry them and refill with fresh drinking water.
OXO describes covered trays as helping keep freezer odors out and marks certain models as top-rack dishwasher safe. IKEA's SPJUTROCKA tray, by contrast, is handwash only. Material appearance alone does not determine care.
