Are you looking for a larger size 6.3 quart capacity ultrasonic cleaner?
RCBS sent over the Ultrasonic Cleaner 2 for a full test and here is how it performed.

Previously I reviewed the RCBS Case Cleaner with a 3.2 quart capacity. This incredible cleaning machine is an ammo reloader’s dream for cleaning cartridge cases and much more.
What if you need more room for extra cases or even gun parts to clean? Better step up to the larger capacity RCBS Ultrasonic Cleaner 2. This almost doubles the capacity of this product over the smaller RCBS Case Cleaner and opens up so many more cleaning opportunities.
Let’s take a look at what the RCBS Ultrasonic Case Cleaner 2 offers:
If you’re looking for a powerful and efficient way to clean your brass casings, the RCBS Ultrasonic Case Cleaner 2 is an excellent choice. This updated model features a larger capacity than its predecessor, with a 6.3-quart capacity that is nearly 100 percent larger. This increased capacity allows you to clean even more casings in a single cycle, saving you time and effort. The Ultrasonic Case Cleaner 2 also features an easily programmable LCD and a timer that can be set for up to 30 minutes of continuous cleaning, delivering clean brass in a short amount of time.
The RCBS Ultrasonic Case Cleaner works best with the RCBS Ultrasonic Case Cleaning Solution, sold separately, and produces perfect results every time.
- 120 VAC
- 6.3-quart capacity
- Stainless steel parts basket
- Smaller stainless steel parts tub
- Limited One Year Warranty

If you worry small parts might get lost, the included smaller stainless steel parts tub is perfect for them.

Interesting note. The RCBS Ultrasonic Cleaner 2 is not just all about cleaning cartridge brass and gun parts. Just add water in it and use the smaller stainless steel parts tub and you can clean your wife’s tarnished jewelry as I did. The RCBS Ultrasonic Cleaner 2 sure worked nicely on them too!

The RCBS Ultrasonic Cleaner 2 works best though for brass cartridge casings and other heavier cleaning needs when you use RCBS’s own cleaning solutions made for their products.
I was sent out a sampling of both types of concentrated cleaning solutions for testing offered on the RCBS website.

First let’s take a look at the star of the cartridge case cleaning market, the RCBS Ultrasonic/Rotary Cleaning Solution Concentrate.

The RCBS Ultrasonic/Rotary Case Cleaning Solution is a must-have for anyone who uses the RCBS Ultrasonic Case Cleaner. It penetrates deep into the small crevices and hard-to-reach areas of your cartridge cases, ensuring that they are thoroughly cleaned. This solution is designed to quickly and effectively remove tarnish, carbon buildup, and metal oxides from cartridge cases, leaving them sparkling clean and ready for reloading.
The RCBS Ultrasonic/Rotary Case Cleaning Solution is also an excellent choice for those who use a rotary-style case cleaner. It works just as well in this type of cleaner and can help users achieve excellent results every time.
Designed for use with the RCBS® Ultrasonic Case Cleaner, the RCBS Ultrasonic/Rotary Case Cleaning Solution quickly removes tarnish, carbon buildup and metal oxides from cartridge cases. The specialized formulation cleans brass cases inside and out, including the primer pockets (spent primers must be removed), producing a bright, professional-grade finish. Ultrasonic/Rotary Case Cleaning Solution is non-corrosive and non-combustible, making it safe and easy to use. One quart of the concentrated solution makes 10 gallons of cleaning mix, and it comes with a built-in measuring cup for use with all brands of ultrasonic cleaners. The Ultrasonic/Rotary Concentrate Solution has anti-tarnish protection and works with rotary style cleaners.

When used for range find brass cartridge cases, the results are incredible. A little bit goes a long way since it is in a concentrate form, so a bottle will last you for quite awhile.
