Bakeware and Roaster dishes - Use and Care Instructions

Non-stick coated Bakeware and Roaster dishes can contain PTFE (polytetrafluoroethylene) and are available in one-, or more-layer versions, as well as with ceramic-reinforced coatings.

The systems are characterised by good scratch resistance, abrasion resistance, as well as the best non-stick properties. Good cleanability is guaranteed.

Bakeware and Roaster dishes should, as a general rule, be protected against overheating above 260°C. Overheating leads to a reduction in the non-stick effect and reduced lifespan. Likewise, we do not recommend the use of metal utensils, and other sharp objects in this type of bakeware.

Notes on use

  • Before first use, remove all packaging and labels. Clean baking and casserole dishes in liquid detergent and hot water.
  • Do not leave empty Bakeware and Roaster dishes in the oven unattended.
  • Use only nylon or wood utensils so as to not damage the surface sealant.

Cleaning and care

  • Clean the dishes using hot water, detergent and a sponge cloth, or with the fine side of a soft sponge. A soft dish brush can also be used to clean the object.
  • Stubborn food residue should first be soaked with hot soapy water.
  • Under no circumstances should you clean the Bakeware and Roaster dishes with the rough side of a cleaning sponge or a metal scouring pad. This will scratch and destroy the non-stick layer.

Generally speaking, non-stick coated items can be cleaned in the dishwasher, however, this is not recommended because:

  • The durability of the dishes can be reduced by cleaning in the dishwasher
