The visible and accessible parts can be shiny by human hands. On the other hand, places that are invisible and inaccessible cannot be helped by human hands. However, unpleasant odors in toilets can also be out of reach of people, such as pipes and septic tanks. So we "cleaned" the cleaning and came to a conclusion.

"Even if people can't reach it, they can go with fungi." It means that Bacillus natto, yeast, and lactic acid bacteria remove the slime in the pipe, eat urine stones, increase the number themselves, enter the sewage tank, and even eat from the source of the smell. We manufacture our own unique detergent (*) that combines these bacteria. (* The liquid is manufactured with reference to a cleaning agent called "Ehime AI", whose manufacturing method is disclosed by the Ehime Prefectural Institute of Industrial Technology.)

The effect is outstanding, just by pouring the cleaning agent into the toilet every day, the odor value of the septic tank will decrease steadily. One month later, the toilet fell to a level where almost no smell was felt.
Cut off the source of the smell with scientific eyes. NEXCO CENTRAL toilet beautification is based on human hands and wisdom.
