Jason, I am not familiar with the product you are inquiring about but the "dust" your leather objects are leaving behind is most likely a result of red rot, a condition which is caused by exposure to sulphur and is unfortunatly irreversible. Generally leather dressings are oil based and designed to soften the material which it is being applied to, if you apply it onto an object which is suffering from red rot, all you end up with is gunk. If you are planning on using this product, ensure that the leather which you are applying it to is in fairly decent condition, or else you could end up with a irreversible mess on your hands...good luck! -Rebecca Bunch.

I see that it is sold in many of the archival catalogs such as University Products but I wonder how safe it is. We have a larger collection of leather goods such as helmets, shoulder pads, and footballs from the turn of the century to the present. Many of our leather helmets from pre W.W.II are fraying and leaving a powder leather dust. The dust is not being cause by infestation but just natural deterioration. The formula is advertised as "proven to give outstanding results on fine leather bindings." Does any one recommend this formula and does anyone think it would be useful for our situation?
