What makes Toilet Shokunin unique is that it is an extremely strong acid that does not damage metal.

It contains acids that are as strong as inorganic acids such as hydrochloric acid, but are not normally used for cleaning.

It can be used to remove stubborn urinary stones as well as troublesome areas where staining would be a problem, so some people use it in sinks and bathrooms.

For stubborn stains around water areas and trays, please consider Toilet Shokunin.
