Chemically, washing soda (sodium carbonate) is identical to baking soda (sodium bicarbonate) except wahing soda has an extra H20 molocule and an exta CO2 (carbon dioxide) molocule. This is why you can easily make your own washing soda by taking regular baking soda and cooking it at 300 dgree F for an hour. The baking soda will release the water and carbon dioxide molocule into the air and your left with washing soda.tom_k/mo wrote:Mike, very interesting. Looking forward to your "After" photos of the caster assys. Can you expound a little on the electrolysis process? You mentioned Washing Soda, is that TSP or something else? Any other details would be appreciated.
Washing soda was impossible to find here in San Diego so I make my own with baking soda and my oven.
