It will burn you, although not a severe as Caustic. Here's a good MSDS

In that case you were using quite a dilute solution

Del:
1kg will do about a bucket full, make sure the water is hot/warm otherwise the oxalic acid crystals will not disolve.

I put about 750g into a gorilla bucket with about 8litres of hot water and it did my GT bars in less than 2-3hours.. just use an old tooth brush and the rust comes straight off.

dj_benice:
just the recommended one  :daumenhoch:  got it from the states :(  I have used a kilo bag of crystals to do a couple of f/f's, bars and some cranks in a plasterers bath.  I used the quantitys advised on vintage which assumes the bits will be allowed to stand for 8 hours plus, 1kilo to a bucket seems a bit excessive or maybe I am just tight  :LolLolLolLol:
