I'm not sure what you expect to happen, but that sounds normal. Stannous solution is colorless. It takes quite a while for all the solder to dissolve, but you don't need it all to dissolve. In fact, you never really want it to all dissolve as your stannous will degrade pretty quickly after it's gone.

Have you tried to use it yet? Dissolve a few of your gold foils in a small amount of HCl and bleach as has been described. Add a drop to a q-tip and add a drop of your stannous.
