About BW urolith remover（urolith inhibitor）

Have you experienced annoying odor in public toilet of stations or parks?  Annoying odor comes from : Uraroma (61%), The odor of excrement (59%) and the staying odor (48%) according to Kao Corporation’s investigation.

This odor is caused by putrefaction of organic substance in urolith and by increase of bacteria. In summer, reproductive activity of bacteria is enhanced and odor becomes stronger.

Urolith which is the cause of odor is stuck to the urinal. Calcium in discharged urine becomes poor solubility calcium compound and becomes urolith, and it may cause pipe clogging. Urolith once adheres to the urinal becomes hard to be removed. Specialist works to remove urolith by using strong removing agent such as “non-medical deleterious substances”.
