Remove mill scale with Picklex


Q. I have read with interest about a product called "Picklex" which can supposedly remove mill scale from hot-rolled steel. Does anyone have experience with this product and does it work as advertised?

A. Hi, Joe.

If anyone has links to peer-reviewed literature, or comments on general technologies, as opposed to testimonials to particular proprietary processes, we'd be happy to see them.

A. The EPA did an in depth study on it. The following is a link to the report. I am going to be using it shortly so I will follow up.

thumbs up signThanks, Darwin!

We linked to the original report on letter 24256 back in 2003; thanks for the link to the followup study.

Please do give us some feedback, hopefully including some actual cost figures, after you've implemented it. It would be interesting to hear from you in 3 years or so as to whether you are still using it, or to hear from someone who installed it 3 years ago and is still using it.

I love progress and success stories, and Picklex and similar processes sound like one. But as a consultant and journal columnist for decades, I made it a regular routine to check up 3 years later on the success stories printed on the front covers of the metal finishing journals. To put it mildly, the glow had gone out in most cases; hopefully that will not be the case here.
