The usage method of Kao washing machine cleaner is as follows: 1. **Preparation**: Confirm the capacity of the washing machine and use it correctly as per the product instructions. 2. **Dissolve the cleaner**: Dissolve an appropriate amount of Kao washing machine cleaner in hot water. The dosage of the cleaner can be adjusted according to the contamination degree of the washing machine. 3. **Put into the washing machine**: Pour the dissolved cleaner into the washing machine. For a pulsator washing machine, set the water level to the high position; for a front-loading washing machine, you can directly pour in the cleaner. 4. **Select the mode**: For a pulsator washing machine, run it for about 5 minutes (you can put in a few rags to avoid idling), cut off the power, soak for 2 to 24 hours (the longer the soaking time, the better the cleaning effect), and finally wash for 5 to 10 minutes according to the standard washing procedure of the washing machine. For a front-loading washing machine, select the cleaning mode or self-cleaning function of the washing machine and start the washing machine for cleaning. 5. **Clean the accessories**: During the cleaning process, you can use a small toothbrush to brush the edges of the washing machine and the filter screen and other accessories to remove stubborn stains. 6. **Complete the cleaning**: After the cleaning is completed, wipe the inside of the washing machine clean with a rag, and then open the door of the washing machine to ventilate and dry. Note: It is recommended to use 90g for washing machines with a capacity of less than 5 kilograms, and 180g for those with a capacity of more than 5 kilograms. When using Kao washing machine cleaner, it is recommended to wear gloves and avoid touching sensitive parts such as eyes. At the same time, maintain good ventilation. If the washing machine has a heating function, using hot water can improve the cleaning effect.
