You can get Industrial Denatured Alcohol (IDA) which is meths without the methyl violet and has the advantage that it is 99% alcohol rather than the regular 90% of meths. The downside is the requirement to have authorisation from HMRC, but for small quantities, it is a fairly quick application process.
