Advice about pickle

[JMDES]

Hi everyone

Excuse the basic question - Im a bit of a newby...

I read somewhere that you can use citric acid as an alternative to the usual pickle. Do you use it in the same way - ie warm?

I'm a bit put off the usual pickle with it having a sulphuric acid base (most likely illogically!) - but when you use that, do you keep topping it up, or do you have to replace it regularly? How do you get rid of it?

Thanks

I've used it in the past; about 10% solution by volume (which was probably quite strong) and warmed in the usual way. It lasted well, but I went back to safety pickle once I'd gunged it up enough.

Disposal was by neutralising with bicarb & evaporating to dry again - it's in a tub under one of my benches. Labelled, thankfully.

The trouble with citric as a pickle is that it doesn't last very well. Have you considered using alum?

Thanks for the advice.

Would you use the alum in the same way?

Yes. Diluted in water and used warm. It's a lot less corrosive, but still very effective. Useful for removing broken drill bits too!

Brilliant - I will try it.

Thanks
