Question about oxalic acid

hello,

I was just wondering how many of you have used this acid in your pickling bath? I have read it is a dangerous chemical but i see that several supply houses sell it,so is it that dangerous or not?I have read that several people recommend citric acid as an alternative.Any thought would be appreciated

Please help.
Thanks!

I didn't find the right solution from the Internet.
