Herm Sprenger developed Diamond Paste to clean and maintain your Herm Sprenger bits, spurs and stirrup irons. If your favorite bit has gotten a bit dull and lost its luster, squeeze a little paste on a cloth and apply it to the surface. Polish with a clean cloth for a sparkling shine. And don't forget to polish your irons, spurs and even the hardware on your bridle for that ready-for-the-ring final touch! Metal cleaner from Sprenger is gentle to your skin - and your horse's skin. It is non-toxic and fragrance free. The paste contains micro-fine polishing granules that efficiently remove gunk and grime and leave a sparkling shine.
