I have one to do tomorow , where a decorater has left a stain from some door handles to a cream carpet, its like a greyish grease like grafite and finger print dust reminds me of the same but maybe its quite different

Done loads of these for insurance companies. Ultrapac or Champion usually shifts it. Acid rinse afterwards.

Pulverised aluminium is the standard powder used by Crime Scene Investigators and it can get everywhere!

If your customer also has it on window frames it can be removed with Fairy liquid.
