The joy Of Citric Acid

[The_Yellow_Ardvark]

Why do I use Citric Acid.

Well, use it cold it will remove the rust, allowing you to crack on with other projects.
Hot, it speeds it up and the playpen gets warm.

A WAFU glue pot, the inner one was long gone, sad.

After soking in Citric acid for a week.

I'll have to remember this. I've recently been gifted a Drummond lathe on which there are several rusty parts. Where/how do you obtain the citric acid? Can you buy powder by the kilo or are you a lemon squeeze?

Try electrolysis. Plenty of info. on it.

I do that as well.

I use solar panel to give me a dc voltage, or a converted computer psu.
For the Land rover chassis I used a paddling pool and a old arc welder.
