I decided tomorrow was the day so I got all my gear out of the garage tonight ready.... and that's when I saw it. my copper chiller, hop strainer and MT manifold were all covered in green copper crud

spent 2 hours scrubbing it off but the hop strainer is too long to get into so I'll have to wait until tomorrow to go out and get a bottle brush. I know I've got one somewhere but you know what its like moving house - things hide from you
still, a lesson has been learned...
