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.
