It comes in an easy-to-use trigger spray and is ideal for cleaning bathtubs, showers, toilets, colorfast fabrics, vertical surfaces, and hard-to-reach spots. Plus, it’s nonabrasive and made with a nonhydrofluoric acid–based formula, which is safer than other similar liquid rust stain removers.
Promising review: “Holy wizardry! Seriously it was more work to clean the mirror over the vanity than use this product. With almost no effort, this made my dark-orange, iron-water shower stall white again. I definitely suggest wearing a mask or bandana and running the ventilation fan if spraying in an enclosed area. Great product!” —Jessica B
