Just that really! Small people have been using the chair and it is now looking rather grim (tide marks from various spillages). What is the best way to get it clean that doesn't involve hiring a wet & dry vac please? It is black fabric and the cover doesn't come off. Today I tried the steam cleaner on it, but it made bugger all difference. I have 1001 carpet spray, but I'm worried that will end up bleaching/discolouring the dark fabric.
