Scrubbing techniques refer to methods used to clean surfaces by removing dirt, stains, and contaminants. These techniques can involve physical scrubbing with tools like brushes or sponges, as well as chemical cleaning agents that help break down grime. Common applications include household cleaning, industrial maintenance, and even medical sterilization. In addition to traditional scrubbing, there are specialized techniques such as ultrasonic cleaning, which uses high-frequency sound waves to agitate a cleaning solution. This method is effective for delicate items like jewelry and electronic components. Another technique is steam cleaning, which utilizes high-temperature steam to sanitize surfaces without harsh chemicals.
