Power Steering Bottle Deposits? 182

[RSR182]

I was looking at a 182 this morning and there was a lot of black build up around (what I think was the) PS reservoir cap, on the bottle itself?

It's the bottle on the top right. I asked about it but they couldn't be sure of what it was.

Could anybody let me know if I'm just being paranoid? I am millimeters from taking it off his hands!

Also the photo and car belongs to Martin_172, sorry for thieving your image! Many thanks

over filled bottle more than likley, pretty rare the bottles are spotless, normally covered in a black oily furry deposits
