Bob750,
Ha! Pretty funny.....I ordered the BlueAway back in February. Actually, its proper name is Blue-Job Chrome Restorer. I ordered it from NWBay.com in Tacoma,WA. It cost $10.95 & $5.65 S/H. Pretty pricey, I thought. Anyway, with enough elbow gease, it will remove blueing but it didn't even touch my stain. I am beginning to agree with the concensus that, since it's on the left side, it probably was battery acid.
