Do I put the laundry tank cleaner through the detergent inlet?

Never add detergent through the detergent inlet.

Pour it directly into the washing tub.

Also, the washing tank cleaner is for one-time use, so please use the entire amount. ~For those using a drum-type washing machine~ Regarding the timing to add the washer tub cleaner to the washer, the method for adding the cleaner differs depending on the model of the drum-type washing machine you are using, so please refer to the instruction manual for your washing machine. Please use the cleaner according to the instructions in the tank cleaning course. Note: If there is no specific information in your washing machine instruction manual, if you add cleaner after water is added, water may overflow from the door, so be sure to add cleaner before adding water.
