Run a batch or two of concrete in it. I really don't think there
is anything in light residue that could harm concrete, the only
things that really affect concrete is sugar and some sulphate
compounds, neither of which I would expect in makeup.

If you are really worried, run a batch of sand, gravel, and water
and let it run until you have new shiny steel.

Most of it washed off with water and scrubbing, but there's
still a
red stain all over inside that wouldn't come off with gunk or
lacquer
thinner. This is definitely not rust.

Is there anything in make-up that can harm concrete?

No, I wasn't making out with the mixer. This thing came from a
cosmetics factory and then sat unused in a warehouse for several
years.

That's right, ladies - your make-up is made in concrete mixers!
