Am I wrong for asking someone who used my grill to clean it?
My wife's son uses my Blackstone often when cooking Sunday lunch,. but he never cleans it. After he left it a mess with all the sugar from a tri-tip marinade, I asked him the following week if he would clean. He said he would. So I went inside and got my water spray bottle and brought it out. By the time I got back he said he was done. The grill still had all the sugars, etc from the previous week. He just scraped all the big pieces off. When I said here is the water, he said he didn't need it When I pointed out all the sugars etc that had caked on the grill, he said it did not matter. He said he would just clean it off the next time he grilled. I told that was fine and I would do it myself. He then blew up at me. I am wrong to expect someone who uses my grill to properly clean it?
