RCBS Formula 2 Media Cleaning Kits Review

The Most Honest RCBS Formula 2 Media Cleaning Kits Review Online

For any serious reloader, the condition of brass casings is paramount. It’s not just about aesthetics; it’s about consistency and safety. I’ve spent over a decade meticulously preparing and cleaning components across various demanding environments, from dusty workshop floors to precise laboratory benches, and I’ve learned that effective cleaning media is foundational. My quest for the perfect brass polish led me to the RCBS Formula 2 Media Cleaning Kits. This particular blend, presented in a 4-pound bag, promises to restore brass to a near-new luster using ground corncobs as its base.

My immediate need for a new media solution arose after a particularly rough batch of .30-06 casings surfaced from a damp storage situation. They were tarnished, showing significant oxidation, and my old generic media was simply not cutting through the grime effectively. I needed something with a bit more bite, a polishing agent that could handle stubborn oxidation without damaging the brass itself. While I considered generic corncob media or other specialized blends, the reputation of RCBS for producing quality reloading components made their offering a strong contender.

Upon receiving the RCBS Formula 2 Media Cleaning Kits, my first impression was one of practical utility. The packaging was robust, containing a generous 4-pound quantity of media. The material itself appeared consistent, a fine granular texture that hinted at its abrasive yet polishing capabilities. My initial thought was a quiet sense of anticipation, hoping this would finally be the answer to my persistent brass cleaning challenges.


First Use Experience

My initial testing of the RCBS Formula 2 Media Cleaning Kits took place in my dedicated reloading area. I poured a substantial amount into my vibratory tumbler, filling it to about two-thirds capacity, which is my standard practice for a thorough cleaning. The media was paired with a batch of heavily tarnished .223 Remington brass that had seen better days.

The tumbler hummed to life, and over a period of six hours, the RCBS Formula 2 Media Cleaning Kits went to work. What struck me immediately was the lack of excessive dust compared to some other media I’ve used. This is a significant plus, as excessive dust can make cleanup a chore. The brass cases emerged visibly brighter, with the dull tarnish significantly reduced.

After this initial six-hour cycle, I ran the brass for an additional four hours. The results were even more impressive; the cases had a uniform, bright sheen, looking remarkably close to new. There was a distinct lack of any scratching or marring on the brass surface, which is a common concern with aggressive media. The media itself, after the ten-hour cycle, showed signs of use but remained largely intact, indicating good durability.

Extended Use & Reliability

Over the subsequent months, I’ve used the RCBS Formula 2 Media Cleaning Kits for a variety of calibers, including .308 Winchester, 9mm, and even some .45 ACP. The performance has remained consistently excellent across the board. The 4-pound quantity has proven ample, and I still have a considerable amount left, making the value proposition quite strong.

In terms of durability, the corncob base seems quite resilient. While it does eventually break down into finer particles with prolonged use, it doesn’t disintegrate into a fine powder like some cheaper alternatives. I’ve found that I can typically get 8-10 good cleaning cycles out of a batch before I notice a significant decrease in its polishing effectiveness. After each use, I simply screen out the larger debris, and the media is ready for its next round.

Compared to my previous experiences with generic corncob media, this RCBS blend offers a superior shine and a noticeably faster cleaning action. While it’s not as aggressive as some walnut shell media for heavy soot removal, for polishing and removing tarnish, it truly excels. It’s a testament to the added chromium oxide cleaner and polisher that RCBS has incorporated into this formula.

Specifications

The RCBS Formula 2 Media Cleaning Kits are fundamentally a corncob-based media. This granular material serves as the carrier for the cleaning and polishing agents. The key specification here is the 4 lb quantity, which provides a substantial amount of media for numerous reloading sessions.

The inclusion of a chromium oxide cleaner and polisher is what elevates this from basic corncob media. Chromium oxide is known for its abrasive properties, making it effective at removing oxidation and imparting a high shine. This combination makes the media suitable for its stated purpose of polishing and shining brass cases to a like-new finish.

This media is described as X-Dry, which is crucial for its performance. It means the media is formulated to absorb moisture and oils from the brass, preventing them from caking or clumping during the tumbling process. This also ensures that the polished brass remains clean and dry after processing, ready for resizing and reloading. The Universal caliber designation means it’s effective for any brass case size you’d typically reload.

Performance & Functionality

The primary function of RCBS Formula 2 Media Cleaning Kits is to clean and polish brass casings, and it performs this task admirably. When used in a vibratory tumbler, the corncob media, augmented by the chromium oxide cleaner and polisher, effectively buffs away tarnish and grime. Cases emerge with a remarkably bright and consistent finish.

Its strength lies in its ability to deliver a superior polish without being overly aggressive. Unlike some harsher media, I have not experienced any instances of scratching or damage to the brass. This is particularly important for reloaders who prioritize case integrity.

However, for extremely heavily soiled or corroded brass, you might need to supplement with a more aggressive pre-cleaning step or extend the tumbling time. While it handles typical tarnish exceptionally well, deeply pitted brass might require more intensive restoration.

Design & Ergonomics

The design of the RCBS Formula 2 Media Cleaning Kits is purely functional, focused on its intended purpose. The corncob material is processed into consistent, small granules that are ideal for tumbling. Its white color makes it easy to visually inspect for cleanliness and debris.

Ergonomically, the material is easy to handle, pour, and scoop. The X-Dry formulation means it doesn’t feel damp or sticky, making it straightforward to manage. There’s no complex setup or learning curve; you simply add it to your tumbler and let it do the work.

The packaging itself is practical, designed to keep the 4 lb of media contained and dry. The simple, no-nonsense approach to the product’s design ensures that the focus remains squarely on its effectiveness in cleaning brass.

Durability & Maintenance

In terms of durability, the RCBS Formula 2 Media Cleaning Kits offer a good balance for a consumable media. The corncob base, while eventually breaking down, holds up well through multiple cleaning cycles. I’ve found that a batch can typically last for approximately 8-10 uses before its polishing power noticeably diminishes.

Maintenance is minimal. After each tumbling session, I recommend sifting the media through a hardware cloth or a dedicated media sifter to remove spent brass shavings, dirt, and any degraded media particles. This simple step helps to prolong the life of the media and maintain its effectiveness. Storing the used media in an airtight container will help keep it dry and ready for the next use.

Potential failure points are inherent to any tumbling media; it will eventually wear down. However, given the price point and the quality of the shine it produces, the lifespan is more than adequate for most reloaders.

Accessories and Customization Options

The RCBS Formula 2 Media Cleaning Kits come as a standalone product, with the primary “accessory” being the media itself in its 4 lb bag. No additional polishing compounds or specialized tools are typically required for its basic operation when used in a vibratory tumbler. The Universal caliber compatibility means it works across a wide range of cartridge sizes without modification.

While there aren’t specific “customization options” in the traditional sense for the media itself, its effectiveness can be influenced by the accompanying cleaning solution or polish used in the tumbler. Some reloaders might opt to add a small amount of their preferred brass cleaning fluid to the media for an extra boost, although the built-in chromium oxide cleaner and polisher often makes this unnecessary. The key is its seamless integration with standard vibratory case cleaners.

Who Should Buy RCBS Formula 2 Media Cleaning Kits?

The RCBS Formula 2 Media Cleaning Kits are an ideal choice for any home reloader who values clean, shiny brass casings. This includes those who reload for precision rifle cartridges where case consistency is paramount, as well as handgun and shotgun shell reloaders who simply appreciate aesthetically pleasing and well-prepared ammunition. If you frequently encounter brass that has been exposed to the elements or stored for extended periods, this media will be a significant asset.

Those who should perhaps skip this product are individuals who exclusively use ultrasonic cleaners or wet tumbling methods and have no need for a vibratory solution.
