All plastics and silicon used in the manufacture of Lékué products are very easy to clean. This can be done by hand with a neutral soap, without using abrasives.

A dishwasher is only recommended if it can be programmed at temperatures that do not exceed those specified on the individual product's packaging and if they are placed on the top shelf of the dishwasher, unless they are products made from SBS plastic, in which case they are not suitable for dishwashers.
