Please dry after the workpiece is rusted or dry naturally, do not wash with clean water. After the work is dry, paint or apply anti-rust oil as soon as possible. In order to achieve a better effect, depending on the situation, a series of high-quality rust inhibitors (oil-soluble, slightly soluble in water, dura mater, dehydration) can be selected.
