Up to now i've only found one place to order etchant solution and it's from radio-shack.

From those are you who are from Canada where do you get your PCB stuff.

In Ontario and Quebec, Activeplus components has quite big network of stores. It is division of Future components. They sell MG Chemicals line of PCB production accesories. www.activestores.com

There was another great place to get PCB supplies called Tectron located in Stoney Creek, ON but it's gone now.

Default HCL + H2O2

This is a very active etchant and you should be able to get the hydrogen peroxide (not the pharma strength, more like beauty supply store strength) and hydrochloric acid pretty easily up in Northland. There is a thread at www.groups.yahoo.com/group/Homebrew_PCBs/
which discussed the chemistry.<p>I've heard of it being used, but never tried it.I guess the best thing
for you to do is try it yourself.<p><em>
In Australia, H2O2 is available from commercial hair dressing suppliers
in about 18% (wt) and sold in 250 ml to 5 liter. The HCl is brick
cleaner, ect and available in most hardware shops, in anything from
250ml to 25 liter and cheap too. HCl is almost always sold concentrated
about 30 to 35% (wt). So going by the reaction

H2O2 + Cu + 2HCl -> CuCl2 + 2H2O

and 30%(wt) HCl = 8.2 Molar, 18% H2O2 = 5.3 Molar
for every mole of H2O2 you need two moles of HCl. i.e ratio of hardware
store acid and hair dressing peroxide is approx.
volume acid * 8.2 = 2 * volume peroxide * 5.3
or
for every liter of 18% peroxide you need 5.3 * 2 / 8.2 = 1.3 liters of
30% HCl solution.
<p></em> I can't vouch for it, but if you do a google search the formula shows up over and over again.

I guess we are blessed with easy access to toxic chemicals here in the states...
