洗衣粉与肥皂混用,可增强去污力有些人用洗衣粉洗衣服时,见衣领或袖口处太脏,就再打一些肥皂,以为这样就会增强去污能力,其实不然。因为洗衣粉呈酸性,肥皂呈碱性,酸碱混合便发生中和,反而降低了去污力,不如再洒些手洗洗衣粉效果更佳。新旧电池搭配使用,可节约电能电池用旧,电能耗完,电阻增大。如与新电池合用时,它实际成了电路 Washing powder mixed with soap, can enhance the detergency Some people use laundry detergent to wash clothes, see the collar or cuffs at the dirty, then hit some soap, thought it would enhance decontamination capability, it is not true.

Old and new batteries with the use of energy-saving batteries can be used, power consumption, resistance increases. When used with a new battery, it actually becomes a circuit
