Cleans Water Stain! Also usable on plastic Removes stubborn "water stain" from bathrooms, faucets, and washbasins, leaving them sparkling clean. 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 "water stain," "black grime," and "sliminess" in the bathroom, and the abrasive component "HA component (hydroalgerite)" removes it completely. 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. ▼ It will be shipped via Yu-packet Post Mini, but the size barely fits through the mail slot, so it will be placed directly into the envelope, and the container may have scratches. Please purchase only if you understand this. ▼ It is currently discontinued and only available online, so the price will further increase and become difficult to obtain in the future. No price reduction, please.
