$2.69/gallon for the muriatic acid and 69 cents/quart for hydrogen
peroxide, this sure beats paying $6/pint for the FeCl.  It works well,
but has some odor.  I used it outside just as an extra precaution.

If I may go off topic on the side of safety and household hazzards.

As you probably found out, the chemicals you used were rather good at
removing metal.  

What you may soon find out, they are SO good, that EVERYTHING metal in
the room in which they are kept will start to rust.  stuff across the
basement and inside of wooden boxes.

I took my Muriatic Acid, sold as such to etch stone and clean
concrete, and I put that into a 5 gallon bucket with a lid that had an
O-ring of silly-cone.
