The Best Way to Clean Reloading Brass: Wet Tumbling for Optimal Results

Introduction

Cleaning reloading brass is a critical step in ensuring the reliability and performance of your ammunition. Over the years, I have experimented with various methods, from crushed walnut shells to hand polishing, but the method that has proven most successful and efficient is wet tumbling. In this article, we will explore the advantages of wet tumbling and provide you with a step-by-step guide to achieve the best results.

Historical Cleaning Methods

Initially, I relied on mechanical methods such as the use of crushed walnut shells in a vibratory tumbler. This process involved loading a mixture of crushed walnut shells and car polish into the tumbler and letting it run for a while. Once completed, the walnut shells were sifted out, leaving the brass behind. The downside of this approach was the difficulty in removing all the walnut shells from the flash holes, and while the brass was clean, it was not perfectly polished.

The Emergence of Wet Tumbling

Advancements in reloading technologies introduced wet tumblers, which utilize a water-based solution and stainless steel pins to clean brass. This method has revolutionized the cleaning process, offering a better balance between cleanliness and shine. Wet tumbling is now a go-to technique for many reloading enthusiasts due to its efficiency and ease of use.

Wet tumbling ensures that the brass not only looks clean but also shines, making it easy to spot any potential issues such as split necks or incipient case head separation. After cleaning, the brass is an ideal candidate for annealing to ensure it is ready for further use.

Getting Started with Wet Tumbling

Here’s a step-by-step guide to wet tumbling brass:

Equipments Needed: Purchase a case tumbler from reputable reloading equipment brands. Perform a Google search to find and contact stores that sell firearms and reloading equipment. Preparing the Brass: Begin by cleaning any residual powder or debris from the brass shell. This can be done using a brush or by swabbing the case with a solvent. Load the Tumbler: Fill the tumbler with water and a cleaning solution. A simple solution can be a mixture of water and a small amount of degreaser or a commercial brass cleaner. Add a few stainless steel or brass pins to the tumbler. Tumbling Process: Place the brass shells into the tumbler and seal it. Choose a duration based on the condition of the brass— around 15-30 minutes is usually sufficient for lightly soiled brass. Rinsing and Drying: Once the tumbling process is complete, remove the brass from the tumbler and rinse it thoroughly to remove any cleaning solution. Dry the brass immediately to prevent corrosion.

Wet tumbling ensures that your brass is not only clean but also shines. It is a versatile and effective method that can be adapted to suit any reloading enthusiast’s needs. Whether you are a seasoned reloader or just getting started, incorporating wet tumbling into your reloading process can significantly enhance the quality of your ammunition.
