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.

How bad they were.

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..

Mix with flour, applied to part, wrapped in cling film, wait.

The man's inspired!

Strange to tell, I've been searching for the ingredients for two "DIY" potions recently: One to soften veneers, and the other is this homemade rust remover.
Had to order the citric acid off eBay - our local chemist "doesn't stock it".
Couldn't find any Arm & Hammer washing soda, so tried with bog-standard soda crystals, courtesy of the local supermarket. Water courtesy of the tap, the dash of washing liquid from t'kitchen.
Having experienced these "home remedies" before, I only made a litre....apparently half a coffee mug is about 100g, and therefore the 40g of soda was about a quarter of a mug.
Have to say it worked a treat, even freeing up a seized up pair of secateurs....

The veneer softener worked as well....glycerine from the supermarket, bit of PVA, some meths and water. Sprayed rather than soaked, then pressed, sandwiched with some wallpaper and plastic sweet pea mesh left over from last year's gardening. Left a few hours, changed the paper, and re-pressed.
Forgot it for a couple of days, then checked again....perfectly flat, and very pliable.

Not often I have two successes at the same time! There's hope yet!
