De-Mineralised water  is ultra-pure H₂O produced through a distillation process that removes minerals, salts, and impurities. This de-mineralised water is ideal for laboratory work, precision cleaning, battery top-ups, and steam iron use where mineral deposits would cause damage or contamination. Its neutral pH and absence of dissolved solids make it suitable for sensitive applications requiring consistent quality. Store in a cool, dry location away from direct sunlight to maintain purity.
