Hi All
I've been given a couple of 30l stainless steel drums which are prefect for storing feints or multiple stripped wash's prior to a spirit run. My problem is that they have a hazardous chemical sticker on the side - Acetaldehyde. I've been told they've been internally washed, but my mate doesn't know how (the guy he got them off a just said they were washed).
I know that acetaldehyde exists in alcohol in minute quantities, however in researching how to clean acetaldehyde, all I get is hazardous spill cleanup documents and in it's pure form it looks like really nasty stuff (including being a carcinogen).
Does anyone with a chemistry background out there know much about this stuff and how I can clean the containers to ensure they are safe? The last thing I want to do is poison myself.
Thanks guys.
