Cleans Water Stain Thoroughly! Also Usable on Plastics Removes stubborn "water stain" from bathrooms, faucets, and washbasins, leaving them sparkling. Effectively removes "black grime" from bathtubs and "sliminess" from drains. Uses ultra-microscopic particles of 10 microns or less, so it won't damage bathroom materials and can be used with confidence. Cleaning Mechanism: The cleaning agent lifts the dirt from "water stain," "black grime," and "sliminess" in the bathroom, and the abrasive component "HA component (hydroalgerite)" removes it thoroughly. Features a natural herb fragrance for a refreshing cleaning experience. ▼ I've used various detergents, from cheap to expensive, but this product removes dirt by far the best. Please give it a try. ▼ Will be shipped via Yu-Packet Post Mini, but due to the size being close to the post slot limit, it will be placed directly into the envelope. Please understand this before purchasing. ▼ Currently discontinued and only available online, so the price will likely increase further and become difficult to obtain.
