Flitz Tumbler Media Additive 7.6oz
Flitz Tumbler Media Additive 7.6oz is a USA-made brass cleaner designed specifically for reloading workflows. The formula is ammonia-free and blends with tumbler media to deoxidize brass, remove powder residue, and restore brightness. Users report shorter cleaning cycles thanks to the additive’s concentrated cleaning action, making it ideal for busy reloaders who want consistent results without harsh chemicals. The product is designed to be used in small amounts—typically 1–2 capfuls per load—so a single bottle lasts through many sessions.
In terms of longevity, Flitz media creates a protective film that helps brass resist oxidation for several months, reducing the need for frequent re-polishing. This long-lasting protection is especially valuable for brass that sits between reloads. The cleaner works well with a range of media and is compatible with both rotary and vibratory tumblers. For best results, pair the additive with quality media and follow the manufacturer’s recommended dosage to balance cleaning power with brass preservation.
Frankford Arsenal Stainless Steel Pins 2 lb
Frankford Arsenal’s 2 lb stainless steel tumbling pins are designed to replace conventional media in rotary tumblers for deeper cleaning. The pins measure 1mm by 7mm and come magnetic for easy handling and rust prevention. This size is well-suited for cleaning interior surfaces, primer pockets, and tight spaces inside brass cases, especially in smaller batches where media can reach difficult areas. The magnetic design simplifies handling and minimizes loss, which is helpful when replenishing pins mid-project.
These pins are described as reliable for cleaning inside the primer pockets and the interior body of cases, making them a go-to choice for reloaders who want thorough interior cleaning without damaging exterior case walls. They work particularly well in rotary tumblers, where the moving pins scrub brass more aggressively than conventional media. For best results, use a compatible tumbler setup and replenish lost pins as needed to maintain consistent cleaning performance across batches.
Frankford InstaClean Brass Cleaning Packs 24 Count
Frankford InstaClean Brass Cleaning Packs come as 24 premeasured packets designed for quick use in wet tumbling. Each pack is formulated to simplify the cleaning process, reducing preparation time between batches. These packs are proudly made in the USA and are designed to work well with rotary tumblers, though they can be used in other wet tumbling setups as well. The premeasured format helps ensure consistent cleaning results across batches, particularly for beginners or reloaders who want predictable outcomes without extra measuring steps.
To use, simply drop a cleaning packet into the tumbler water with or without stainless steel media and start tumbling. The packs are versatile enough to pair with various media choices, making them a convenient option for reloaders who value simplicity and reliability. Replacement packs are readily available, which helps maintain steady workflow and reduces the risk of running out of cleaning supplies mid-project.
Frankford InstaClean Quick-N-EZ Vibratory Tumbler
The Frankford Arsenal Quick-N-EZ Vibratory Case Tumbler is a compact, reliable unit designed to clean brass quickly with easy monitoring through a clear viewing lid. The bowl design promotes efficient brass agitation, speeding up cleaning while reducing wear on reloading dies and extending brass life. This system is easy to operate, with a simple ON/OFF switch for safety and convenience. The tumbler is often used with walnut or corn cob media to achieve a balanced finish that’s suitable for reloading.
For users who value speed and simplicity, Quick-N-EZ excels in delivering fast, repeatable results. It works well with the Frankford InstaClean Packs to create an all-in-one cleaning workflow or can be paired with other media types for more aggressive cleaning. The unit’s durable construction and straightforward design make it a practical option for hobbyists and serious reloaders alike who want dependable brass cleaning without a steep learning curve.
Hazelnut Shell 18/40 Abrasive Media
Hazel Shell 18/40 Abrasive Media provides a natural, abrasive option for brass cleaning in vibratory or rotary tumblers. Sized to 18/40, this media is designed to clean and shine brass while offering a different abrasion level than synthetic media. It’s a bulk-friendly option for reloaders who prefer a traditional polishing approach, and it’s compatible with a wide range of tumbler configurations. The 10 lb bag option makes it well-suited for large batches, reducing frequent replacements and providing consistent polishing outcomes across sessions.
When using hazelnut shell media, it is essential to monitor the finish to prevent over-polishing, especially on delicate brass. The media’s natural abrasive qualities work best when paired with appropriate polish or cleaning agents and within a tumbler program that allows time for controlled abrasion. This option is particularly appealing to users who value a classic polishing method or want to diversify their media mix for different brass conditioning goals.
Buying Guide
Key purchase considerations help you tailor media choices to your reloading workflow. Below are practical factors to weigh when building or refining a brass-cleaning setup.
- Media type and cleaning goals: Choose ammonia-free liquids like Flitz additives for decoxidizing and polishing, or steel pins for interior cleaning. Natural media such as Hazel Nut Shell offer a gentler abrasive option for polishing without excessive wear. Consider whether you need surface cleanliness, interior cleaning, or a balance of both.
- Rotary vs. vibratory tumblers: Pins excel in rotary systems and can reach inside primer pockets, while traditional media or premeasured packs work well in vibratory tumblers for quicker surface cleaning without deep interior scrubbing. Your tumbler type should guide media selection.
- Ease of use and consistency: Premeasured cleaning packs reduce measurement errors and speed up workflow. Liquid additives provide strong cleaning power with a small dosage but require careful dosing to avoid residue buildup. Assess your preference for convenience versus adjustable cleaning strength.
- Media lifecycle and replacement: Reusability varies by media type. Ammonia-free liquids may require periodic replacement to maintain cleaning efficiency, while steel pins and nut-shell media have different lifespans based on brightness goals and abrasion levels. Plan for replenishment intervals to maintain consistent results.
- Batch size considerations: Heavier media like 2 lb pins or 10 lb hazelnut shell lots are ideal for larger batches or frequent reloading, reducing the frequency of media changes. For smaller batches, compact options and premeasured packs can optimize space and reduce waste.
- Safety and disposal: Ammonia-free products are generally safer and easier to handle. Follow manufacturer instructions for disposal and avoid mixing chemicals that could produce harmful residues. Use in well-ventilated areas and wear eye protection when necessary.
- Brand reliability and USA-made options: USA-made products often provide consistent quality and support. Reputable brands like Flitz and Frankford Arsenal are widely used by American reloaders, contributing to predictable performance and easier sourcing.
- Cost vs. value: While bulk media can be more cost-effective, consider the cost per brass-cleaning session, longevity of the media, and the potential need for occasional replacements to determine overall value.
In summary, the best tumbler media for cleaning brass depends on your equipment, batch sizes, and preferred finishing results. For speed and interior cleaning, stainless steel pins offer deep scrubbing but require a compatible tumbler. For surface polishing with minimal hassle, ammonia-free liquids and premeasured packs deliver consistent results. Natural shell media provides a traditional polish with a different abrasion profile. By aligning media choices with your tumbler type and cleaning goals, you can optimize efficiency and brass lifespan without sacrificing safety or quality.
