Problem belongs to youngest daughter & her tribes' converted van they use when their kids are attending motor x meetings.
They've just returned from a recent event & had some exhaust problems with the van in the way to the event then again on the return trip accompanied by another problem - which I forget.
Anyway... when they were emptying the van of the bikes & associated stuff they noticed that the carpet fitted to the sides of the van were covered in diesel black soot type stuff & as they will be using the van - problem now fixed - next weekend for another event they want to clean the crap off.
Never having come across this before I could only suggest a liquid type carpet cleaner... so now looking to the wisdom of the forum for any suggestions.
