We are interested in making a compost tumbler out of a used 55 Gallon Plastic Drum. Problem is, the drum previously contained paint thinner. The typical ingredients of paint thinner include the following:
Mineral spirits
Acetone
Turpentine
Naphtha
Toluene
Methyl ethyl ketone (MEK)
Dimethylformamide (DMF)
2-Butoxyethanol, or any of the other glycol ethers

Is there a recommended method for thoroughly cleaning a drum such as this to be used as a composting bin for an organic garden, or would it be recommended that the drum not be used for such purpose at all?

I thank you in advance for your advice and suggestions.
Jenny

No.  No one in industry studies this.  Things are recycled, but not reused.  No one want a surprise, so no one want to risk it, so there isn't a definitive answer.

No.  Here's what I've said before, and other people have opinions, not answers.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Thank you. I was afraid that might be the answer.... just trying to save a buck, but not worth it when it comes to contaminating food we will consume.
