I was on the quest to find a suitable leather cleaner for a Ted Baker wallet I use. I sought some assistance at David Jones, and they recommended the Mimco Leather conditioner ($14.95) for my needs. The staff member serving me used a small amount on my wallet to double check that it would remove dirt, and keep the leather component of my wallet shiny.
It is surprising to note that I only need to use a pea size amount for this purpose, on a soft make up removal pad. Take care when using this product though, as it is quite runny. This will last me a while.
