Hello. I was cleaning my grubby ivory steering wheel using saddle soap and a microfibre cloth. Noticed a 3cm line in the leather and thought it was a mark I'd made. Rubbed it gently and now the crack has spread(discoloured the immediate area) and I am getting annoyed and concerned. Could I have unwittingly gone through the surface? I wasn't putting much pressure on. Has this happened to anyone else? Loath to keep at it in case it spreads further. Its unsightly now and directly at the 'top' of the wheel so right on the eyeline. Help!
