Easily clean by preventing black spots!
Bleaching power prevents black spots and keeps the toilet clean!
● The color of the flowing water is colorless, so you can see the state of urine and feces.
● Slight fragrance that does not bother the smell of bleach.
● Standard use can be used for about 1 month (3-5 weeks). (It will vary slightly depending on temperature, water temperature, water volume, etc.)
● "Bluelet leave bleach" does not damage the equipment in the tank, it does not affect the bacteria in the septic tank and the septic tank and dew-proof tank, so you can use it with confidence.
