Will ultrasonics remove rust?
Rust forms when iron and oxygen react in the presence of water or moisture in the air. Small and large metal parts are all susceptible to rust, as well as large machine parts if they are neglected and get wet or damp.
Parts and tools with cracks, crevices and pivots are very difficult or impossible to reach using dips or mechanical methods to dislodge rust deposits. Traditionally, rust was removed using steel wool, solvents or immersing in strong acids. However, where parts are worth restoring, ultrasonics using Aqueous Alkaline cleaners is proven to be the fastest, most efficient and environmentally friendly way to remove rust.
Ultrasonic cleaning uses a much faster and more thorough technique to remove rust than traditional methods. It works by producing longitudinal waves in the liquid where the parts or elements to be cleaned are immersed. They break the links of the particles that are not part of the component, but are housed in it. Ultrasonic washers, either with water or using a specific solution, create small pressurised bubbles that removes the rust from the component.
In summary, dirty or rusted metal parts such as pumps, gears, and mechanical equipment can often be restored in an ultrasonic cleaner.
