What items should NOT be washed in the Bosch dishwasher?
Items not recommended for dishwasher use include acrylic, adhesive-joined pieces, bone-handled utensils, iron, pewter, brass, bronze, tin, and wood. Paper products, plastic bags, and packing materials should also never be loaded. Only wash plastic items if they are marked 'dishwasher safe.' (Page 6)
