I made a test with about a 35% methanol to water mix in a clean container,
and it did get milky and it did get warm. Over ther first 24 hours there was no
apparent settling or change in colour, but after 48 hours I can see a clearer
layer forming at the bottom of the container. It is currently about 1/3rd of
the total sample.I shall continue to observe
After discussing the matter with the supplier of the methanol, it appears that
he recycled a container that had previously held another product. So he has
undertaken to replace the contaminated product with 20 litres decanted into
a fresh new container. I shall test a sample before using it to make sure it
remains clear after mixing.
