I live in a downstairs apartment, using electrolysis in a five gallon bucket should be no problem as I can sit it outside the back door. My question is what do I do with the brown muck in the bucket when I’m done?
The liquid is only water, rust and your electrolyte (I use washing soda) so it’s safe to pour down your drain. I have a utility sink I use, but if you don’t want to pour the solution in your sink then just dump it in the toilet and flush it.
