Amazing result for only 10 minutes in the oxalic bath. What strength was the acid solution?
Good work, it has come up a treat. Leon.

Thanks guys! i used mix. 100 grams oxalic and 50 grams citrid acid and 250ml winegar to 8l of water. I do not know about the mixture does it make any better effect on the cleaning.. a little testing Ouch that must have hurt! That's why I use chemical-resistant gloves and other protective equipment.. Just in case
