Yes, this is not a problem. The dinnerware may be exposed briefly (less than 2 hours) to a temperature above 70ºC, so a hot wash in your dishwasher won't cause any problems. The temperature of your dishwasher's hot wash program is usually only high for a short time. The standard we comply with is based on this practical situation, so our products can be cleaned in the dishwasher safely. All our products are safe for both children and adults and comply with European legislation and regulations for consumer products that come into contact with food and drink.
