Used to clean my motorcycle leathers. First washed with PH neutral cleaner and allowed to dry, then applied to the jacket with a rag, soaking the jacket. Once it had dried it went Matt not shiny, and was less stiff than before feeling more supple. Note to self, don’t hang near a radiator, they had dried hard so was going to replace them, until I breathed new life into them with so much suppleness and no greasy shine either. Best product I have ever used for leathers only I had to use 3/4 of a bottle due to the stiffness, now they are as good as new. In my video you can see mid clean how dry the leather was and how much difference it made
