EM bacteria are a collection of beneficial bacteria that are originally found in nature and are gentle to both people and the environment. When EM active liquid is sprayed, the beneficial bacteria become dominant and exert their power against harmful bacteria and unpleasant odors. Example: In a 500ml spray bottle, add water and 7cc of the liquid (using the cap of the pictured plastic bottle). It's ready to use! There are many situations where it can be used. Instructions are included. Spraying it inside the room: * Reduces dust on the flooring. * Creates a comfortable and pleasant space when sprayed indoors regularly. It also works well in: * Drains * Toilets (for ammonia odors) * Cloth diapers and in nursing care situations. It can be diluted 100 to 1000 times, so you can use a lot of it. The contents are the same as in the third picture. Available for sale: 500ml for 1320 yen. Shipped in a pouch. The image is a sample. Why not try EM active liquid? I'm enjoying life with EM active liquid, which makes cleaning easier and easier!
