Cleaning a surface using a solution containing a large number of micro to nano scale bubbles has significant advantage regarding environmental protection. This review first briefly introduces the cleaning mechanism of micro-nano bubbles (MNBs), including physical and chemical effects. Then the applications of MNBs in cleaning of metal parts, precision parts, cultural relics or food are introduced. After that, coupled cleaning method of ultrasound and bubbles is introduced. Finally, the characterization methods for the cleaning effect are introduced, which mainly focuses on the changes of physico-chemical properties (mass or cleaning area, infiltration, colony number and light scattering intensity) of the cleaned parts or that (like conductivity) of the solvent. It is believed that MNBs technology will be applied in a broader range of surface cleaning applications.

使用含有大量微米到纳米级气泡的溶液清洁表面在环境保护方面具有显着优势。本综述首先简要介绍了微纳米气泡（MNBs）的清洗机理，包括物理和化学作用。然后介绍了MNBs在金属零件、精密零件、文物或食品清洗中的应用。然后介绍了超声波和气泡的耦合清洗方法。最后介绍了清洗效果的表征方法，主要侧重于清洗部件的理化性质（质量或清洗面积、渗透、菌落数和光散射强度）的变化或（如电导率）的变化。溶剂。
