Can I use bokashi liquid as a toilet cleaner?

Yes, bokashi liquid can be used to keep the pathogens at bay, but it won't be as effective in removing the stains.

Fermented liquid can be used to keep harmful microorganisms, algae and unpleasant odor in check, since it contains a number of beneficial microorganisms and has low pH levels. You may use it as a cleaning product, but it is less efficient in removing tough stains.
