NORTHWEST ENTERPRISES Ultrasonic Carburetor Cleaning Solution, 1 Gallon Concentrate — Fast-Acting, Aluminum-Safe

NORTHWEST ENTERPRISES Ultrasonic Carburetor Cleaning Solution (1 Gallon) is a concentrated formula designed to remove varnish, gum, dirt, and other deposits from carburetors and small engine parts when used with an ultrasonic cleaner.

If you restore engines, rebuild carburetors, or maintain small machinery, choosing the right ultrasonic cleaning fluid matters. This one-gallon concentrate is formulated to work with ultrasonic machines to loosen and lift contaminants from interior and exterior metal surfaces without aggressive mechanical scrubbing. It’s intended for hobbyists, mechanics, and shops looking for a product that targets hard-to-reach crevices, blind holes, and delicate components that traditional cleaners or aerosol sprays struggle to access.

How does this solution work with an ultrasonic cleaner?

The formula amplifies the ultrasonic process: microscopic vacuum bubbles generated by the machine implode on contact with parts, producing tiny shock waves that dislodge deposits. Because the bubbles penetrate very small cracks and recesses, the action reaches areas manual methods miss, delivering thorough cleaning without abrasive contact.

• Optimized for ultrasonic cavitation to remove varnish and gum.
• Penetrates blind holes, passages, and minute crevices.
• Removes deposits from both interior and exterior surfaces.
• Works faster than manual scrubbing or aerosol cleaners.

Is this safe for the metals in my carburetor and engine parts?

This cleaner is formulated to be safe on a broad range of metals commonly found in engines and carburetors, including aluminum, brass, copper, cast iron and several alloys. The product avoids harsh ingredients such as borates, phenols, nitrates and butyl cellosolve, reducing the risk of corrosion or surface damage when used as directed.

• Safe on aluminum and aluminum alloys used in many carburetors.
• Compatible with brass, copper, and copper alloys.
• Suitable for cast iron, ferrous metals, magnesium, and zinc alloys.
• Formulated without SARA 313 or EPA 33/50 listed ingredients.

How quickly will parts be cleaned, and what parts can I treat?

Cleaning time varies by soil level and ultrasonic unit, but many small parts show visible improvement within minutes. The concentrate works well on carburetors, throttle bodies, valves, rocker arms, heads, seats and other small engine components that collect deposits over time.

• Fast action—often cleans small parts in minutes with proper equipment.
• Ideal for carburetor bodies, jets, floats and passages.
• Effective on valves, heads, rocker arms, and heat exchanger pieces.
• Also suited for motorcycle and automotive small-part restoration projects.

How should I use and dilute the concentrate for best results?

Follow your ultrasonic machine manufacturer’s guidance for temperature and agitation, and dilute the concentrate according to the level of contamination. Warm solutions typically speed cavitation, but avoid overheating; use only recommended concentrations to protect delicate parts and seals.

• Mix concentrate with water to the ratio recommended for light, medium, or heavy soils.
• Use warm (not boiling) solution to improve cleaning speed and effectiveness.
• Rinse parts after cleaning to remove loosened residues and neutralize residue.
• Dry parts thoroughly before reassembly to prevent corrosion.

Who is this for: NORTHWEST ENTERPRISES Ultrasonic Carburetor Cleaning Solution is aimed at mechanics, engine builders, restoration enthusiasts, and repair shops that use ultrasonic cleaning equipment. It’s suited for anyone who needs a concentrated, metal-safe cleaner to restore carburetors and small engine parts to serviceable condition without aggressive mechanical abrasion. Use it when you need reliable penetration of tight passages, fast results, and compatibility with a wide range of metals commonly found in automotive and small-engine systems.
