It is sure that the plate regularly goes into the dishwasher but unfortunately despite having washed and oiled by hand, the plate quickly takes black spots of cooking. As I wash at 75 ° with high-end product.
In short, the term "everyday" is spoofed, it would be rather 1 to week and again.
The drip tray could be chromed or coated with special paint as my previous Tefal (15 years of loyal service every day) to also pass in the dishwasher, where it has rust very quickly. Its material is not pleasant to the touch for manual washing.
By cons, cooking side, ease of use, washing, it's still a great but only occasionally BBQ;)
