Trying to clean up ink from a printer cartridge.....Forget it! It'll wick out as soon as you touch it.
Leave the chems on the van. If it isn't in very big splats, and hasn't soaked down to the base of the pile, you should be able to re-tuft it very easily. That's the only way I've ever resolved printer ink spillages.
It's a judgement call as to whether to pay you to do this or just make a claim.
