Hi
After researching this subject washing powder does not work, it has to be soda crystals to create the electrolytic path between the anode and cathode. The supply is also important and needs to be DC. I use a 12V DC power supply. This was, then rigged up in a project box to keep everything together and allowed a little but more control with an additional on/off switch. I have since also put a digital volt/amp meter as well but this is not essential, as is the on/off switch. You can also use an older style battery charger I believe the new ones sometimes do not work.
There is a lot of information on this subject and better-qualified people than myself to advise you on HMT on this topic. But, if I can help further please ask.
