The joy Of Citric Acid

[The_Yellow_Ardvark]

No idea. I have certainly kept citric acid mix in a sealed plastic container for a couple of months with no obvious loss of omph.
To be honest it is so quick and cheap to make a batch I tend to just put it down the sink once it starts to get too dirty and make a fresh batch.

I decant mine into a 25lt container, filtered through a filter.
The crud settles out, then that gets disposed off.
Then I had more citric acid powder as and when I want.

The rust is gone, the pits were there before the dip in Citric. Here they have had a coat of machine wax.

Water was at 18deg C.
Heat will speed it up.

That tap wrench looks to have turned out really well. Haven't done anything with electrolysis for years, might have to revisit it.

Did anyone figure out how to turn the liquid into a "paste", so that it can be applied to surfaces that are too large to dip in a container ?

Yes, I have..
