Try one of your solvents first Dave (obviously not on bonded/bitumen etc). Then detergents/HWE. I guess you could try a gel spotter too. The trouble with liquids is they go further down the pile making it harder to remove. Then there is the question of colourants. If she's already had a go herself I would forget it if there's a lot.
I did a quote a few weeks ago and the daughters bedroom was absolutely mullered with make up. It just wasnt worth it. The custy appreciated the honesty, I ended up doing the whole house (very big!)
Hope this has helped, at least a bit anyway LOL
