I don't clean a great deal that is older than twenty five years old.

I was asked to look at some graffiti on a marks & Spencer, marble fronted.

I went into some detail on poultices so I have some knowledge.

I would suspect that there is something off the shelf that would have evened the side up

If you wasted a good yoghurt that's your fault - I would have eaten it

Graffiti ie paint is a different animal as it very rarely really penetrates the surface (to any depth). Pen is more of a stain which if mobilized again by the addition of say a solvent it travels deeper whithin.
 
Nettle and bee stings /and ant spit is what you should use to remove graffiti from painted/delicate surfaces.

Hey Rob that was almost a sensible/interesting conversation we had it's getting boring...what about my boots?

I keep bees - I'll introduce a spittoon into the apiary just incase I get Earl down this way

It's Ant spit and bee stings you need to collect ...not bee spit.
