The TEX Tuz Ruhu is a powerful cleaning solution based on hydrochloric acid, designed to tackle the most stubborn limescale, rust, and persistent grime. This 2380 ml formula works effectively on sanitary fixtures, tiles, ceramics, and porcelain, making it a practical choice for restoring the cleanliness of acid-resistant surfaces in your home. To use it, simply apply the liquid directly to the affected area and let it sit for several minutes before rinsing thoroughly with water. Because of its strong active ingredients, you should always wear protective gloves and ensure the room is well-ventilated during application. The solution comes in a robust plastic bottle with a red cap for secure storage, though it must be kept away from marble, granite, and aluminum to avoid damaging these acid-sensitive materials.
