If you can't get it off...Costco has a great return policy.
I had a ss BBQ and all the pop rivets rusted and it started to fall apart. Took it back and asked when I got it. I said a couple of years ago...they looked and looked...manager joined in the computer search. Found it. Sir you got this 4 years ago...no problem...BTW they have a new model out and the defects have been resolved. Had this BBQ probably 5 or 6 years now. Great return policy!👍
