Cylinder contamination

Loneshark · 22nd June 2006, 11:58

Took 2 3l cylinders in for testing, and had the centre ring me today. One cylinder was contaminated with a "black residue". The centre have steam cleaned it and shot blasted it, but it's still there!
Any ideas what it might be, where it came from and how to shift it?

Cheers

Chris

What was the cylinder used for? O2 or dil?

Just had air in it. Not been used for a while as been abroad, so was well out of test. Can't think of anywhere "strange" I would have had it filled. Our compressor is triple filtered......
