Ultrasonic cleaning concentrates significantly enhance the effectiveness of the sound: They dissolve grease, oil, polishing pastes, flux, and particle residues faster, protect delicate surfaces, and shorten processing times. Neutral, alkaline, and acidic formulations are available depending on the task. Neutral cleaners are suitable for jewelry, eyeglasses, precious metals, plastics, and delicate surfaces. Alkaline products are the first choice for stubborn industrial and workshop contamination such as oil, grease, soot, or machining residues. Acidic concentrates are effective against limescale, rust, oxide, and mineral deposits – for example, on stainless steel, glass, or certain metal alloys, provided the material is compatible.
Select the concentrate appropriate for the material and type of dirt. For aluminum, brass, die-cast zinc, and coated parts, follow the manufacturer's recommendations; if in doubt, a material test is recommended on a non-critical area. Flammable solvents should not be used in the ultrasonic bath. After cleaning, the parts should be thoroughly rinsed with water and dried; for acidic media, a neutral rinse is recommended to avoid residues.
The optimal bath setting depends on the product and application. Dosages in the range of approximately 1 to 5 percent have proven effective, combined with moderate bath temperatures and a contact time appropriate to the contamination level. Before first use, the fresh bath is degassed to ensure even cavitation. Clean baskets and regular media changes ensure reproducible results; filtration or oil separators can increase service life and reduce costs.
With the right chemistry, every ultrasonic bath becomes a stable, material-friendly process – from a quick shine for jewelry and optics to thorough intermediate and final cleaning in laboratories, dental practices, workshops, and industry.
