Hi Chris

Before you spend your money go to the supermarket, buy
a bottle of Muriatic Acid (Hidrochloric Acid, HCL,
http://en.wikipedia.org/wiki/Hydrochloric_acid ), plus a bottle
of Hydrogen Peroxide (H2O2,
http://en.wikipedia.org/wiki/Hydrogen_peroxide )

And, carefully melt them with your FeCl. First the HCL and later the H2O2

Here is the detailed info, but, it's in spanish :P
