Bags - I clean my leather handbags and have a special cleaning solution to do this with. I regularly clear out bags to get rid of cluttter and I sometimes hoover inside my bags. Cannot stand crumbs/crap inside a bag. Beach bags (fabric) I put in the washing machine.
Jewellery - I use regularly use cleaner & polish cloths. If an item has gone discoloured/tarnished and cannot be fixed then I wouldn't wear it again.
Shoes - repair/clean/wipe. I bin any that are significantly damaged or scruffy/tatty from over use and beyond repair.
Anyone else ?
