Electrolysis issues

[Blackfoot58]

I’m pulling my hair out in this one. I did industrial electrical work for about 30 years: 480 3 phase through various DC control voltages. I understand the way it works. My smart charger was stopping the process. I now have a 12 volt 120VAC to 12VDC converter. It is basically a battery tender/charger. Clean positive steel (mower blades) and good connections. Arm & Hammer wash soda, the target, negative, item has been cleaned for good connection at both ends. Here’s what I get via my Fluke meter: 14.2VDC checking between water and positive connection. Great bubbles & some cleaning. If I try to adjust the piece so it is submerged better, I get around 1.4VDC and the charger won’t kick into charge mode. With charger unplugged, I have no continuity across the water. Is that due to too little soda? Normally water is not good continuity probe to probe.

To experiment (hey it's only water and electricity....)
Run straight water and see what your power source does.
We don't know your maintainer , it could be smarter than those of us putting electricity in water...

You are increasing the conductivity by adding soda.
( I use just a little in my mini set up.)

This article suggests no more than a rounded tablespoon per gallon.

Spend 22 minutes and watch this video-pretty basic and I like big brush(s) idea over any other sacrificial piece.

That's really good, I'm thinking of a project that it might work on. Gently though as it's brass. Crazy on how much srubbing it took to get it that far along.

Will do. Thank you.

I used 1/3 cup to every 5 gallons

Not that it matters but use baking soda as electrlyte and stainless as my sacrificial metal and jut an old car charger.....then patiently wait. I am an electrician and never thought to take readings, never has been necessary. Keep at it though, you will get it.

Good video. I’m doing pretty similar. 2 things I’m changing after the video. I’m going to start smaller and use a 12V transformer like he did. Then see if I can clean a small piece. I’ll also try his soda salt mix. Thanks again

i used a big wall 12 volt transformer and powdered citric acid used in canning fruit. To get more coverage i used a big loop of concrete reinforcement pencil rod. I was doing optimus and primus hiking stove steel cases. The loop just fit in the plastic container and speeded up the process as you got 360 degree coverage.

I down-sized and am using a 12VDC 200mA charger. It appears to be working. I have 14.55VDC at the connections. It will be slow, due to the very low amperage. Much better than “not working” with higher amps.

I use an old 12 volt battery charger and a watering trough or a plastic highway crash barrel. That's a trunk lid for a model A ford the top is setting on plastic spacers to keep out of the muck. It helps to rinse off when needed in this case it was taking the old paint off. Crash barrel with a hood panel suspended I normally use a whole box of washing soda mixed in a bucket with hot water cleaned metal needs to be protected from flash rust. I use rebar or whatever metal I have for sacrificial anode.
