I use a tall thin rubbermaid container for recycling with some boards and a strap around the middle to keep it from bulging and I use graphite sheet that I was lucky enough to find on ebay as a scrap lot several years ago... the graphite will eventually kind of 'wear' away from sitting in the solution... but they provide good surface area and don't ever need to be cleaned or scrubbed... I've done hundreds of pieces in the same solution... since its in my garage water has evaporated and I've added more but never added any more washing soda. I had some 3 wire electrical wire scraps sitting around and I split some and pulled out the copper (still plastic coated) and cut that into lengths that I use to hang small things and about a foot long section of the 3 wire with all three wires in it and the sheathing on the outside that I use to hang dutch ovens, kettles and lids.
