Have a 9 year old HM city sofa set. bought it over 2 years ago and though we didn't buy a cleaning/conditioning kit, i have wiped it down with mild bar soap and water every 6-8 months since. just now i noticed one section of one cushion seems "dry" and has a sort of rough texture to it just in one area. looking closer, it looks dry and has a lot of small cracks. is there something I did or didn't do to cause this and is there any way to prevent or slow this problem? I don't mind buying a conditioning kit from the now approved leather solutions but want to be sure that is the answer before buying. The couch does have a fair amount of fade, mostly from the PO's. Any advice? I assumed i was taking care of these pieces correctly at minimum with the soap/water regimen...
