I found an old (fully rusted solid) chain last week,and I chucked it in a bucket of the famous "Oxalic Acid"to see wot would happen, well,to cut a long story short,I FORGOT about it and now (one week later) I just pulled it up outa the GOO and hosed it down and gave it a quick scrub with an old toothbrush ,and believe it or not this chain looks like new, ----- so ---(breath here and keep talkin) --- if I submerge it in oil and let it soak for a day or 2 do YOU think it will become usable again ? or shud I trash it ???
