What precautions should be taken when using dewaxing water
1. When using dewaxing water, the best process flow shall be set under the guidance of professional personnel according to the material, structure, wax type, oil stain amount, equipment, etc. of the workpiece. The use methods include hot soaking, ultrasonic cleaning, etc.
2、配制溶液时，应将水参加洁净槽中，一般加热至35-40℃左右，边搅拌边缓缓参加所需比例的除蜡水，要充沛搅拌平均，升至所需温度即可使用。
3、为失掉最佳清洗效果，依据清洗对象和脏污水平，将除蜡水原液与水配制成浓度为5%～10%的清洗液。加温至60～85℃结合超声波设备清洗3～10分钟后，用纯水漂洗洁净后再烘干。
4、为保持最佳清洗效果，清洗工件不得相互重叠，每天应活期添加1～3%的除腊水。
5、用同一个槽对多种不同材质的金属除蜡，需注意除蜡顺序，先处置生动金属，再处置不生动金属（如：除铜和锌合金表面的蜡层，要先停止锌合金的除蜡，接着再做铜及其合金。不推荐停止少量铜或其合金后接着做锌合金，否则会在其表面形成一层结合不良的置换铜）；除蜡水清洗锌合金类生开工件，注意清洗时间不宜过长、清洗温度不宜过高，否则对工件会发生轻蚀现象。
6、溶液维护：当除蜡效果分明下降，可凭经历补充除蜡水而维持，当油腊、油污量太多时则需要改换清洗液，视清洗工件的状况而定，一般改换周期为2～10天不等。
