GE JGP979 - Manual (Page 16)

The grill burner should be cleaned after
each use. It can be cleaned with a non-
abrasive pad or in the dishwasher.
Rinse and dry thoroughly before using
again. For heavy soil, the burner
should be cleaned first with a soapy
steel wool pad, rinsed and dried. Then
it can be cleaned in a self-cleaning
oven for two hours. NOTE: Check to be sure all burner ports
are open. To open clogged ports, insert
a twist tie directly into each port.
