If you have a mixer that wasn't cleaned out and the cement has dried, throw in a handful of rocks, a dash of diesel and then switch it on and light the diesel it'll take every bit of cement off the drum.

Diesel will not burn on its own. If you throw a match into a bucket of diesel the match will go out.

Diesel will not burn on its own. If you throw a match into a bucket of diesel the match will go out.

If it's getting rumbled and tumbled around a lot, it might vapourise to the point it will light.
Never tried it, just guessing.
A sunny day will be better for it anyway.
