I have noticed a few people replying with comments similar to yours in the last couple years but I have also heard the opposite, here's one such post. I am not in your country so I can't test this but if it doesnt work, even trying it with a mini A/B with some pre made spice, then switch to other solvents like xylene and crash it out using FASA (u will need fumaric acid).

There are many methods for extraction, not just A/B and STB, have a look here. Also look at dry teks and FASA. I also hear your "methylated spirits" is 95% ethanol and 5% distilled water, go have a look at the spec sheets if you will as that is only what I have read.
