Go to Wal mart get HTH PH-minus (sodium bysulphate)in the pool area.  Don't
get PH plus it is different.
Use the PH minus for copper also but use a different batch for steel or
copper.  It is a lot cheaper than sparex
It is about $10 for 10#
Will take mill scale in a couple of hours and heavy scale you need to work
with a brush
Mix a capful to 5 gal of warm water.
I think I converted Tom Talane' to it from the vinegar he was using.  He was
getting pure vinegar at $80 a gal.

Ray,

Why  "DILUTED" vinegar??  Are You diluting the vinegar, or are you buying 
diluted vinegar?

I have started using vinegar for both mill scale and fires scale and I am 
pretty much pleased with the results.  However, it seems to loose strength 
pretty quick so why dilute it in the first place??   I am using the vinegar 
that comes in gallon jugs at the supermarket.
