This weekend we spent some time cleaning up our brew kettle. After sitting in the same spot for 13 years in it’s former home, it developed a bit of grime and rust on the steel plate underneath the kettle. This plate isn’t stainless, like the rest of the kettle, but it sits beneath the outer steam jacket and acts as a protective base-plate for the whole tank.
In the pictures below you’ll see that we lifted the kettle onto some concrete cinder blocks, so it would be easier to work underneath. The first step is to get rid of the surface grime & rust with a wire brush, then treat it with a little phosphoric acid to remove the rust and mineral deposits, and re-condition the steel.
I’ll post more pictures to show our progress on this later in the week.
