The great thing about this site is the wealth of information available, buried in the archives. Before my KKs arrived, @MacKenzie initiated me in the ways of the Curly Kate. I thought it was an exotic new tool and was almost disappointed when I found out how mundane it is. But it works. I did try the wrench but I am too impatient to work each bar individually. Instead I have one curly kate near the BBQ which I use immediately post cook and then, if I want to get things super clean, I soak my (cooled) grates in a water heater base. All down the power of the internet. I couldn't find the water heater base in the UK so ordered one from the US on eBay and there was a video on the Guru site showing how to block the hole off. Easy peasy.
