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、純水：純水就是比較干凈的，有些對于清潔要求比較高的部件會用純水作為介質，比如清洗一些眼鏡、化驗室用的燒杯、試管等。

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+清洗劑：在工業清洗中，水+清洗劑這一組合是常見的，也是巴克做的較多的設備。機器加工業、壓鑄工業、汽車零部件工業、航空航天工業、船舶工業等行業的零部件清洗，一般適用。

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、防銹劑：金屬加工件在生產加工和運輸過程中容易生銹，這就需要使用防銹油在金屬表面形成一層膜，防止金屬銹蝕的化學物質。防銹劑作清洗介質，既可完全清洗工件，又可有效保證工件在一定時間內不會生銹。

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：顧名思義，洗板水就是用來清洗線路板上的液體，而線路板是不能用水洗的，這樣就需要的溶劑清洗線路板，洗板水就是這樣的存在。與其它金屬工件相比，線路板比較“脆弱”，因此一般將電路板放置在夾具中，防止因超聲波振動而對電子元件有損壞，再放入超聲波清洗槽中，確定超聲頻率及清洗時間。

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.
