That’s certainly your choice, but I would suggest having it cleaned first and you might find its not as bad as you thought. Everyone thinks their grill is the worst we’ve ever seen and in some cases they are right, but in all cases they have been surprised with the results of the cleaning. I have never had a customer tell me they wish they had thrown it out instead of having me clean it. A cleaning certainly costs less than buying a new grill and new grills never fit in the same hole as the last one making you hire a contractor to retro-fit your counters.
