Picked up my freebie drum from the maintenance guys today, but I'm not too sure about this one.
It's a Mobil Grease, XHP 222 drum. We use this stuff to grease up forktrucks and manipulators in a higher-heat environment.
The drum is unlined, and I'm wondering if even a blazing-hot burnout is going to be enough to get rid of all of the residuals, considering this stuff penetrates and holds pretty darn good.
Of course, the drum says not to reuse, but I believe all petroleum-based products have that warning on the sticker. Maybe I should call a local refurb shop and see if they use these types for refurb? Might give me some indication on whether it'll be able to be cleaned out or not.
