Can Methylated Spirits be made safe to Drink ?
No. Methylated spirits (aka meths) is a mixture of ethanol and (poisonous) methanol, with a denturant added to make it foul tasting. There is no effective way of seperating them, be it by distilling, using carbon, or filtering through bread (old wives tale). Do not add meths to anything you ever intend to distill or drink, and don’t try using it in any form – it will still be poisonous. Keep it for cleaning and starting the BBQ with. Likewise, you cant “clean up” antifreeze in your still.
