Safety Warnings

It is important to handle Bloo in-cistern blocks with care as they contain sulfuric acid, mono-C12-18-alkyl esters, sodium salts, and other harmful ingredients. These substances can cause skin irritation and serious eye damage, so it is crucial to wear protective gloves and eye protection when using the product. Keep Bloo out of reach of children and avoid contact with aquatic life due to its harmful effects.
