I tried wavelet decompose and tidied up the colour residual image with some success.

Not something I use very often, so I usually have to fiddle around with it.

Although it says B & W the image obviously has to be in RGB mode.
then it is set up like this: http://i.imgur.com/rLhrbI8.jpg - all layers - bottom (desaturated) layer active - output to a new file.
