Ruben and all,

I've cleaned other types of rocks with a water jet tooth brush set up
in the past. It could have used a lot more pressure. I've also
baking soda blasted fine metal parts with my bead blaster. A Dentist
quality water jet would work very good, I would think. Do not know why
that would not work for the irons???

Jim
