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.

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.
