Know about sodium metasilicate

When mixed with water, sodium metasilicate makes a highly effective cleaner that can remove dirt and marks from walls in preparation for painting and attack stubborn soils on siding when cleaning the exterior of a home. Follow label directions for proper use – even a small amount of phosphate-free TSP powder dissolved in water produces a powerful cleaner.

Sodium metasilicate is highly alkaline. Dust from the powder can irritate the nose, eyes and lungs. When mixed with water to form a cleaning solution, prolonged exposure to this compound can cause skin irritation. Wear protective gloves, eye protection and long-sleeved shirts and pants while using this product. Wear a dust mask while mixing the powder with water if dust irritates nasal passages.

Sodium metasilicate is highly poisonous when ingested. Store it out of the reach of children or pets.
