Electrolysis question

[Mike(NEOhio)]

Put a part in yesterday, first time I've done it. It bubbled merrily for several hours but I didn't leave it on overnight. Turned the charger on this morning and no bubbles. Question is, does the soda get used up? Then less ionization so no current? Small batch, around three gallons. So, add more soda or brew up a new batch.

it usually has to be left on for me overnight about 1 to 2 full and compete days 1.5 to 2 amps depending on what charger you have

Be certain sacrificial anode is positive.

There is a point it stops but not usually the peroxides fault the part gets the black coating on it and that seems to stop the process it can only work so long time to wipe off the black and get ready to paint

Clean your anode daily, and check the connections, My big tank has almost 250 gallons in it, I “freshen” it up a couple of times a year with a couple of cups of washing soda mixed in a gallon of hot water. I agree, 24-48 hours will clean almost any part.If you’re gonna do small parts, I get the 5 gallon buckets at Home Depot with the lids so the solution doesn’t evaporate or get spilled between uses

I used vom to check the status anode to cathode.

This is something new to me. I would like more information on this process.

Just search 'electrolysis rust removal" or similar phrase. Tons of articles and youtubes on it. All you need is a plastic tub or bucket, some washing soda, a piece of scrap steel and a battery charger.

Very interesting.

it's a great, non-destructive way to remove rust(and a lot of times, old paint) here's some stuff I've done through the years -

Been working on the H governor housing and dash panel. It takes a while and I need to clean off the anode every couple of hours. I find it's a line-of-sight process from the part to the anode.
