No conditioners or cleaners for pebbled leather, only a damp cloth. Conditioners, cleaners and protectants can actually cause the leather to unpebble. I live in Michigan and have used pebbled leather in the winter without problems. Snow, salt and other wintery messes have all come off with a damp cloth.
I don't have children so I don't have baby wipes laying around but I probably wouldn't risk it. There is a chemical on the wipes that could potentially damage the leather.
^I have never had a scratch on any of mine.
