Can I use the Hornady Sonic Solution to clean my unprimed rifle brass cases like the Hornady 458 Lott?

No, this specific formula (Item #043360) is engineered strictly for firearm metal components and parts. For cleaning cartridge brass, you must use Hornady One Shot Sonic Clean Cartridge Case Solution (Item #043355) to avoid potential damage or improper cleaning results.

What is the correct dilution ratio for the 32 fl oz bottle, and how much working solution does it produce?

The solution requires a precise 40:1 dilution ratio using 40 parts water to 1 part solution. A single 32 fl oz bottle will yield roughly 10 gallons or 38 litres of working solution, providing approximately 64 tank refills for a standard 1.2-litre ultrasonic cleaner.

How should I store this solution during hot Australian summers given local temperature limits?

The manufacturer specifies a maximum storage temperature of 49°C. You must store the bottle in a tightly sealed, upright container away from direct sunlight, taking extra caution if keeping supplies in a shed or vehicle during extreme outback heat.

Do I need to take any precautions if my ultrasonic tank was previously used for cleaning brass cases?

Yes, if the tank was previously used for brass cases, you must thoroughly wash the tank bowl with soap and water before introducing gun parts with this solution. Failing to do so can cause suspended brass micro-particles to bond onto steel firearm components.

Sonic Gun Parts Cleaner - Hornady 043360

Hornady One Shot Sonic Clean Gun Parts Solution (Item 043360) is a concentrated cleaning liquid designed specifically for use in heated or non-heated ultrasonic cleaner tanks. Formulated for disassembled firearm metal components, it rapidly penetrates, loosens, and suspends baked-on carbon fouling, grease, unburned powder residue, and oils without damaging factory finishes. The chemistry is safe on steel, stainless steel, blued, and Parkerized surfaces across ultrasonic hardware brands, including the Hornady Lock-N-Load 1.2L, 2L, and Hot Tub models.

Key Features

High-Yield Dilution: Formulated for a precise 40:1 water-to-concentrate dilution ratio, allowing a single 32 fl oz bottle to yield approximately 10 gallons (~38 litres) of active ultrasonic bath.
Targeted Firearm Chemistry: Removes stubborn carbon and fouling from steel components including bolt carrier groups, handgun slides, barrels, trigger assemblies, and choke tubes.
Wide Operating Window: Works effectively in heated ultrasonic tanks operating between 40°C and 60°C to accelerate fouling removal, with a solution boiling point of 100°C.
Eco-Friendly Handling: Meets RCRA definitions as non-hazardous waste in its unadulterated concentrate form and is biodegradable prior to heavy metal contamination from firing residue.

Who is the Hornady Sonic Solution For Firearms for?

Competitive shooters servicing high-round-count bolt carrier groups — requires the 40:1 dilution ratio of this ultrasonic gun parts cleaning solution to produce up to 38 litres of working fluid, providing roughly 64 complete tank refills in a standard 1.2-litre ultrasonic cleaner for frequent post-match maintenance.
Gunsmiths and armorers cleaning heavily fouled firearm metal components — relies on the 8.19 lbs/gal fluid density formula to penetrate deep mechanical crevices, breaking down baked carbon in ultrasonic baths heated up to 60°C while remaining stable during storage below 49°C.
Hunters maintaining action and trigger assemblies after extended field use — benefits from the 32 fl oz concentrated bottle size to mix fresh cleaning baths that strip field grime, moisture, and dried lubricant off blued and stainless steel assemblies without manual scrubbing.

Less suitable for: Cleaning cartridge brass cases, which require a dedicated cartridge case cleaning formula (such as Hornady Item #043355) rather than a gun parts formula, or environments where workshop or vehicle storage temperatures exceed 49°C.
