This product is amazing! Do you have docs that you need some help breaking in? Use this! Clean and condition? This is what you are looking for. Multi use, and the outcome is always excellent. Being picky, I don't think the sponge will last the entirety of the product, but thats not even close to a deal breaker for me. Once Ive used it all I will order more, but a little goes a long way so I suspect this will last me a long time.
