At MJR Tumblers, we know that the difference between a "nice" rock and a show-stopping gemstone often comes down to one critical, yet frequently overlooked step: burnishing.
What is Burnishing?
Burnishing is the essential final "cleaning and brightening" stage of the tumbling process. While the polishing stage creates the shine, burnishing removes the microscopic film of polish and minerals—often caused by water hardness—that can leave your stones looking hazy or dull once they dry.
How It Works
- Deep Cleaning: It flushes out lingering slurry and grit trapped in tiny crevices or "vugs" that water alone cannot reach.
- Surface Brightening: For rocks, it strips away stubborn residues to reveal the true "wet look" luster underneath.
- Metal Finishing: For jewelry and metals, burnishing goes a step further by smoothing out microscopic peaks and valleys through "cold flow," which compresses the metal's surface to create a mirror-like finish and increase surface hardness.
Why MJR Tumblers' Proprietary Blend is the Best
Our specialized Burnishing Soap is not just your average soap that can actually cause more harm than good. We’ve developed a Proprietary Blend specifically formulated for high-performance tumbling.
- No "Concrete" Residue: Unlike common detergents, our blend acts as a powerful water softener, preventing polish from drying into a rock-hard residue.
- Barrel Safe: Many household soaps contain additives that can degrade rubber tumbling barrels. Our blend is strictly pH-balanced and oil-free to protect your equipment.
- Superior Luster: Our proprietary formula creates a high-density, frothy slurry that holds contaminants in suspension, ensuring they rinse away completely rather than settling back onto your stones or metalwork.
Target Applications
- Primary: Rock Tumbling: Use after your final polishing stage for 1 to 4 hours (or overnight) to achieve that professional, mirror-like finish.
- Secondary: Jewelry & Metals: Perfect for use with steel shot to brighten silver, copper, and brass. It removes oxidation and surface burrs while work-hardening the metal for a more durable finish.
Pro Tip: Perform the "Buffing Test"—rub a dry, polished stone vigorously on a piece of denim for 10 seconds. If it gets shinier, you need a burnishing cycle with our Proprietary Blend.

Jerky
Set name: Variety Pack Pack of 3
It’s tasty but I prefer more spice. It’s dry not wet which I prefer. A little pricey.

They’re expensive, but they’re actually really good
Set name: Variety Pack Pack of 6
Honestly, these are expensive. So if you’re not picky or you don’t really care about your beef jerky, then you don’t really need this one. But if your pallet desires the finer beef jerky in life, and this is the way to go. I took a risk with it and I’m glad I did otherwise I would never have experienced this delicious taste before. I can’t describe it to you, just buy it and eat it and you’ll understand, but only if you really care what your beef jerky taste like, if you can’t tell the difference between amazing jerky and awful jerky and don’t worry about it
