This stuff is great! I didn't know what else to use to try to clean and deodorize all my sandals, because no matter what I tried, I couldn't get them to smell fresh and new. I do a lot of walking in summer, so my sandals weren't terribly fresh-smelling anymore. I cleaned them all one day, and I've got nearly new sandals. One product I had used in the past helped, but had a very strong chemical odor, so I didn't use it much. Nikwax has a clean, pleasant smell.
