LindaL,
Let me tell you a little story of why I swear by Harness Honey (can get it from Ozark Mini). In our round pen we had a large plastic barral that we put our harness in everyday after using it. Winter came and we forgot about the harness. When summer came around, hubby and I couldn't remember where the 'work' harness was....until we went down to the round pen! When we opened the barral there sat the harness, dirty and very green with mold. Needless to say, we figured it was ruined. Hubby took it to the house, threw it down and thought the summer sun would take care of the mold (it didn't). The harness layed in the sun all summer. I remembered I had bought some kind of harness cleaner. I found it and figured I certainly couldn't hurt the harness, so I scrubed it with dawn, put it outdoors for several days to dry. After it was dried I brought it in and used this stuff called Harness Honey on it. When I was finished, I can honestly tell you we couldn't tell the difference between that harness and another that had been kept in the house.
