Miele H 387-1 B Operating Instructions Manual page 45

The removable back panel and roof
liner are coated with a dark catalytic
enamel.
Circulating air in the oven deposits oil
and fat on the back of the oven. These
deposits are burnt off from the catalytic
liners when the oven temperature
exceeds 390°F (200°C).
The oven and accessories should be
cleaned after each use, so cleaning
does not become more difficult.
Allow the oven to cool before
cleaning. Danger of burns!
Do not use abrasive cleaning
agents, hard brushes, scouring
pads, cloths, steel wool, knives or
other abrasive materials.
Do not use oven sprays on catalytic
surfaces. Chemicals used in oven
sprays will damage the catalytic
enamel.
^ Catalytic surfaces should be cleaned
using a solution of hot water and dish
soap with a soft nylon brush.
