Cleaning 55 gallon drums?

[jthomps123]

I've just acquired 2 - 55gal drums from a car wash. Car wash/wax used to be in them. There are even 'corrosive' labels on them.
My questions is how/if i even can clean these for use as an ro/di resevior
If not for an ro/di resevoir, how about a resevior to feed the ro filter?
Thanks for any input.

I don't know Man, No way to tell if any chemicals will leach out.

I agree!

Too big a risk! Leaching is a big problem! Save yourself the possibility of any problems and get a couple 55 gal rubbermaid cans!
