I do pretty much what DriveNJ does, just use Lexol Cleaner as my cleaning agent. I use a natural fiber vegtable brush, covers a lot more area than the toothbrush, when doing big areas like carved fenders and skirts. Tooth brush is good for small spaces.
I start with the blower method, air compresser, vacuum cleaner on blow instead of suction. Just get the dust out from between the layers before dampening anything.
If saddle is older, at all dried out, I would not do the sunshine on leather. This time of year the heat is brutal in drying things. I clean and let saddles sit in shade of the barn or house to dry and absorb the Harness Honey. I hate how Neatsfoot feels on leather. Would NEVER think of using Linseed Oil, that is for wooden items like shovel handles.
I also LOVE the Harness Honey, use it liberally on our leather goods.
Over this last year, I have purchased and cleaned three Western saddles, that ended up NOT fitting my horse!! I cleaned them totally, REALLY used up a lot of Harness Honey in getting them back to the soft, flexible leather they should be. I was shocked at how thirsty the leather was, used several applications before the Honey quit soaking in and needed wiping off. Leather was perfect when finished, had feel, not limp, but soft and bendy for using. One saddle was only 5yrs old, a good brand, but obviously NEVER had been cared for since they won it. Had trophy fenders with the year on it. I guess they used it for rough work, since silver was also bad, in a greenish condition. We had to use the polish wheel to get it back to shiny. Nice quality of silver, just no care. The people who bought the now, nice feeling saddles, all commented on how “good feeling” the leather was to touch. Not oily, but soft, easy to turn stirrup fenders to put your feet in. Leather quality was back to where it should have been because these were nice saddles with good names. I also got compliments on how great the silver looked!
I apply the Harness Honey to both sides of leather if possible, like fenders. I put the saddle upside down on the saddle stand, unfasten the buckles and take off stirrups. This way I can rub the Honey thickly on every layer, between layers and on straps until softened again. I wait about 48 hours between applications to make sure it has really soaked in. Some parts are then moisturized quicker than others, so just the heaviest parts get more coats.
I have never used a nicer product for conditioning leather, and leather stays nice for a long time of use too. I need to use liquid dishwashing soap to remove Honey from hands, but they are not nasty feeling, nor does Honey take off your callus’ like Lexol conditioner does. I NEED those callus’ to protect my hands!! Seems to be a very gentle product and worth the cost, lasts quite a while.
