A few questions about electrolysis...!

Post by Roughwood » Wed Jan 09, 2019 11:18 am

Good morning all.

I have decided to make my own electrolysis kit, principally to have a go at cleaning some biggish iron objects, such as a possible medieval horse shoe, and have some questions. I have consulted previous posts in this forum, but I would like to double check before I get going. ::g Don't want to kill myself or anything.

1 Is it OK to use a car battery charger instead of some other type (such as a mobile phone charger?) The reason I ask is that I have a redundant one in my garage.

I'm not an electrician, so here is the info on the label of the charger:

Input: 240V - 50Hz / Output: 12V DC
Input: 180 VA max / Output: 5.5 Adc (8A rms)

2 Do you use stainless steel for the anode?
I'm sure that I have read that you should not as it can make the electrolyte/water solution dangerous to handle/dispose of. However. lots of people appear to recommend it...

3 What is the ratio of Bicarbonate of soda/salt to water when you make up the solution?

Whilst the internet is a fantastic resource, I have found so much conflicting advice and decided that I should ask here as hopefully some of our members will possess this knowledge.

Thanks for taking a look and I look forward to your replies. :)

All the best,
Mike

This thread is worth a read:

And the online iron electrolysis guides:

Don't use stainless steel, just use plain iron or steel. "Lots of people recommend stainless steel" - that's the internet for you, everyone has an opinion ....

I've just done it with a phone charger, in a glass jar for small items like hammies, i believe depending on what u are doing a harmful gas can be produced?,and don't leave it unattended, might even pay to wear gloves / glass, or is that me being overcautious, prob pay to look right into it on a few different sites and keep charger clips well away from each other, on hammies i got similar results with just spit and baco foil without the worry ....be safer to get a wire brush out :D good luck ::g

Might be able to see the mushroom clould from where I live as u are in Norfolk :D

hello, i bought one many years ago as a full kit, proper charger/croc clip/ and stainless steel plate, very good on iron artifacts/ bronze coins, DO NOT OVER COOK just leave in solution until only the crud dissolves, dry off and smear on some micro crystal wax to preserve the item,

i have done quite a few roman bronze coins, even old grots can be cleaned but as i said do not over cook as it will dissolve to nothing, try a test piece first,
