@Inger5...Yeah that is a really interesting question Inger, thanks for raising it.
We are fortunate to have a barbeque that would scorch a hole in hell!! It gets seriously hot, and I insist that if a guest wants to use the grill they place aluminium foil (which is supplied in a roll next to the appliance) over the grill. I explain I am not trying to keep the barbeque in pristine condition....it is after all 23 years old but, as far as I am, concerned it is a health issue, and different people have a different idea of 'clean' and I want it to look super clean!!!
I do keep the plates totally covered with large ceramic tiles when not in use to deter vermin! You may think your grill is clean but I can assure you, you don't know who visits the plate in the night!!
Had a situation once where a group of us were sitting around the outdoor table having a chat when one of the group said...
"I just saw a rat climb up into your barbeque"!!!!
After I scraped myself off the floor I motioned to the guest next to the gas igniter to hit the button when I told him!
I turned on the gas valve and just waited for about 15 seconds and then told John to push the igniter.
Well, all hell broke loose, there was this substantial boom and the hood of the barbeque rose a couple of inches and this rat ran out with his tail on fire. Since then I am super clean where the Barbie is concerned and I want guests to be too!
Cheers.....Rob
