1. Tap water: it is not only a common cleaning liquid, but also a basic liquid. Generally, tap water can be used to clean stains on workpieces or parts, including small ultrasonic cleaning machine to clean jewelry, etc. only tap water can be used to clean.

2、纯水：纯水是比较干净的，有些对于清洁要求比较高的部件会用纯水作为介质，比如清洗一些眼镜、化验室用的烧杯、试管等。

2. Pure water: pure water is relatively clean. Some components with high cleaning requirements will use pure water as the medium, such as cleaning some glasses, beakers and test tubes used in the laboratory.

3、水+清洗剂：在工业清洗中，水+清洗剂这一组合是常见的，也是巴克做的较多的设备。机器加工业、压铸工业、汽车零部件工业、航空航天工业、船舶工业等行业的零部件清洗，一般适用。

3. Water + cleaning agent: in industrial cleaning, the combination of water + cleaning agent is common, and it is also the equipment that buck does more. Parts cleaning in machine processing industry, die casting industry, auto parts industry, aerospace industry, shipbuilding industry and other industries is generally applicable.

4、防锈剂：金属加工件在生产加工和运输过程中容易生锈，这需要使用防锈油在金属表面形成一层膜，防止金属锈蚀的化学物质。防锈剂作清洗介质，既可完全清洗工件，又可有效保证工件在一定时间内不会生锈。

4. Antirust agent: metal processing parts are easy to rust during production, processing and transportation, so it is necessary to use antirust oil to form a film on the metal surface to prevent metal corrosion. Antirust agent as cleaning medium can not only completely clean the workpiece, but also effectively ensure that the workpiece will not rust within a certain time.

5、洗板水：顾名思义，洗板水是用来清洗线路板上的液体，而线路板是不能用水洗的，这样需要的溶剂清洗线路板，洗板水是这样的存在。与其它金属工件相比，线路板比较“脆弱”，因此一般将电路板放置在夹具中，防止因超声波振动而对电子元件有损坏，再放入超声波清洗槽中，确定超声频率及清洗时间。

5. Board washing water: as the name suggests, board washing water is used to clean the liquid on the circuit board, and the circuit board cannot be washed with water. Therefore, professional solvent is required to clean the circuit board. Board washing water exists in this way. Compared with other metal workpieces, the circuit board is "fragile". Therefore, the circuit board is generally placed in the fixture to prevent damage to electronic components due to ultrasonic vibration, and then placed in the ultrasonic cleaning tank to determine the ultrasonic frequency and cleaning time.
