It may be a regional thing too. Checking Lowes in north Seattle today, I found Kleen Strip Green Denatured Alcohol. The MSDS shows less than 10% Methanol or Methyl isobutyl ketone, which is about the same stuff as the Crown and certainly an improvement over 50-50 ethanol/methanol mixes. (See http://www.wmbarr.com/product.aspx?catid=97&prodid=201 for label and MSDS PDF's). I'm happy to see this change in the product.
It is recommended for use as fuel on the label:
"Fuel: Produces a hot, clean, odorless and smokeless flame in alcohol burners and marine stoves. Always follow appliance manufacturer’s instructions."
