I'm also glad the mystery is solved, i was starting to believe some people
must have been drinking the ethanol when it attacked their plastics, but
you guys are not crazy after all, it is just your suppliers mixing nasty
stuff in there rendering it useless.
I will pester the chemicals shop people until they surrender either the
name of the supplier or the denaturing agent, i promise. But i will have
to wait until i need to make a purchase, to aid in loosening their tongue.
They dispense all chemicals in the shop from larger tanks so i do not know
what manufacturer it comes from. It may even be different from the usual
stuff that you get in DIY stores.
I have used denatured ethanol in a tin can from a paint manufacturer
before, and it was the same on plastic. But i can't find a MSDS for that
brand.
