For a quick wipe down, I use baby wipes. Water works fine also. Every three months or so, I use a leather conditioner that I bought at a shoe repair shop. They also have leather cleaners there. I actually don't let Chloe up on the leather (I heard that gasp out in the Basset world -- don't worry, she has her own loveseat!) as I don't want to deal with additional messes on the leather. I have enough cleaning issues with two kids under the age of six!
