Washing dishwasher-safe products may cause faster deterioration of their visual properties compared to hand washing over time. If it is important for you to maintain the appearance of your tumbler for longer, the manufacturer recommends hand washing with a gentle sponge. The temperature maintenance parameters provided refer to a full container, unopened for a specified time. Opening the container and partially emptying it will result in a faster loss of the initial temperature.
