If you are repainting and you know that they are steel/cast iron with no aluminium components, then hot water and caustic soda will clean them up as clean as you could want along with removing the paint. A good rinse with water afterwards and you are good to go.
Definitely don't do this in the kitchen and wear gloves and face protection as a minimum. Don't pour it on the lawn to get rid of it either as your lawn will be an ex-lawn wherever it hits.
Caustic will dissolve skin in high enough concentrations. You can buy it in supermarkets though

Second repair went beautifuly. No undercut and wetted in nicly.
For thoses interested. Ac, 100amps, 80%en and 150hzs.

Well done, glad it all worked out.
I wonder if the electrodes would have worked for you on the last repair as you seem to have got the cleaning issue sorted.
Anyway, good job, you did what you had to do to get the job done and that's what it's all about

I did wondar too, got them installed on the lathe and its all sweet now.
