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.

Semi-tough and inexpensive
Color: Blue
I purchased this watch because I needed one that I could put into harms way without hesitation; I also needed it to survive. Inexpensive and semi-tough. A tall order. So far so good! Bonus points for appearance. Color coordination and it looks pretty good, lightweight and adjustable for the cost of three gallons of gasoline!

Getting more for the price point!
Color: Green
The MDC 12/24 Hour Military Wrist Watch, with Date and Day ostensibly is an homage to the old military issue watches of the WWII era. At this price point my expectations for look, style, performance, durability were not very high. I was pleasantly surprised! The watch comes in a small black slender box within a sleeve, protected by felt cushion cut out in the shape of the watch. Immediately, what I term a "utilitarian elegance" jumped out at me. Very handsome and durable look that hints of delicate handling but is hefty and rugged. It is a minimalist watch with simple but lasting durability and precision. I've worn the watch for over a week, and though this is not a great deal of time nor is this a comprehensive review, I've so far come away with the impression that with the MDC you are getting more than you paid for. Keeps great time and if you should ding it or scratch it, you wont feel guilty considering the price point. In fact, I am so impressed with this time piece that I bought a total of three (one in each color offered).

Comfortable - rugged look.
Color: Black-Green
Comfortable - rugged look. Battery lasted 2 years and 2 months. Did buy again as it was less expensive to buy the watch again than replace battery for me. Actually was $3 less on the 2nd purchase.
