Hi Leon. Sure. This is my setup, inside the boiler is my grain basket. I set up a simple circulation from the boiler through the pump, plate chiller, and back to the boiler via the spray nozzle in the lid of my boiler.

I put 10 litres of cold water in the boiler and heated it to 60C using the boilers own heating element and then added 200g sodium hydroxide. Left it circulating for 4 hours and I opened, and part opened the taps periodically to get into the ball joint. Emptied, rinsed and then filled the boiler with another 10 litres of cold water which I treated with Starsan to give an acid wash. This isn’t the best acid but it’s what I had to hand and was a bit of a faff because of all the foaming. A wash and a rinse later and all is done.
Anything else you wanted to ask about?
