Know before you buy
This formula is designed for hard surfaces like ceramic tile, glass, fiberglass, and stainless steel. It is highly effective on showerheads, faucets, and sinks, but you should avoid using it on natural stone, marble, or colored grout, as the acidic nature of the product can cause damage.
No, this formula is completely free of bleach and phosphates. It relies on citric acid to break down mineral deposits, making it a more manageable option for indoor use since it does not produce the harsh fumes associated with bleach-based cleaners.
For most applications, you can spray the area and let it sit for a few minutes before scrubbing and rinsing thoroughly. If you are dealing with heavy, long-term buildup, you may need to repeat the process or let the solution penetrate the deposit for a slightly longer duration.
Yes, it is safe for use on kitchen fixtures like stainless steel sinks and faucets. Because it is unscented and free of harsh bleach, it won't leave behind strong chemical odors, though you should always rinse surfaces thoroughly with water after cleaning.
Yes, the professional-grade formula is specifically engineered to dissolve rust, making it suitable for metal tools and equipment. Just be sure to rinse the items completely with water immediately after the rust is removed to prevent any potential surface etching.
