Technical Information

3.8 Wood

Wooden items, whether lacquered or not, are not suitable for washing in a
dishwasher.
Lacquered wood swells and as a result the lacquer peels off. Wooden
cutting boards or items with unlacquered parts (e.g. cutlery with wooden
handles) become bleached and rougher, and can develop cracks.

3.9 Plastics

Most plastics commonly used domestically such as styrol-acrylonitrile
(SAN), polycarbonate (PC), polyethylene (PE) and polypropylene (PP) are
suitable for washing in a dishwasher. Exceptions to this are polystyrene
(PS), high impact polystyrene (HIPS) and polymethacrylate (PMMA).
When cleaning plastics, the following should be noted:
1. To prevent deformation, wash programs with low temperatures
2. If plastic items are washed in a dishwasher over a longer period,
3. Plastics have a hydrophobic surface and therefore poor wetting
(< 122°F) should be selected.
slight discoloration can occur. Discoloration can also be caused
when plastics come into contact with strongly colored foodstuffs
such as beets, carrots or tomatoes.
properties. This has the consequence that drops develop during
drying. Additionally, plastics have poor heat retention properties
so more time is required for drying than with other items in the
dishwasher.
