DIY Telescoping Round Tube

[Paul Moir]

There really is no "too late" with pickling. I've done welds that are several years old. I guess unless you get a crevice going, but that's easy to fix with a welder.

Paul the pickling will remove the black oxidation and surface rust correct?

[Paul Moir]

Yes.

If you've got some of the real heavy black stuff similar to stuff that's badly oxidized (sugaring / popcorn on unsheilded side) that will be hard to entirely remove. But 99% will come off with a quick wire brushing or just a manual scotchbrite pad scrub while you're neutralizing the pickle juice. (Use baking soda & water).

The only issue is with pinholes or other crevices which will cause pitting corrosion, producing rust spots.

Wear gloves if you don't want to have yellow nails and eye protection if you like seeing!

Thanks Paul and I am very familliar with the PPE for acids.

If only I'd follow my own advice....

(I guess that makes me a safety hypocrite?)

I hear you, I usually need a reminder every so often usually as a burning feeling on my hand or some new holes in my jeans. I also work with hydrogen peroxide and that is always fun.
