What concentration of oxalic acid do you use and for how long do you submerse the items in the solution?
I tried oxalic acid and found that it changed the colour of the paint work.
Wouldn't residue of oxalic acid slowly corrode the metal over time unless maybe the oiling will help prevent that. I once heard of someone having restored an item after using oxalic acid only years afterwards have having problems with residue reaction. I was told that by boiling the item afterwards in water helps to remove any traces of acid.
What have you found from your experiances in using it?

Hello,
I use 100g oxalic acid for 1 liter of (very) hot water. I will soon try with less acid.
I first try with 20 minutes submersion. It could remove some paint, especially if you brush with something ... euh... strong (i dont find other word, sorry for my mistake).
I try stell wool, it's effective for rust, but agressive for paint. For more accurate work, I work with a nail brush (used when you brush your hand). If the fisrt bath is not effective enough, you make another one.
Next, you have to rinse with clear water and protect wiht linseed oil after dry.
I hope that you understand my bad english!
