MCE Distilled Deionised Water Spray (500ml) - ART.039

Technical purity for precision rinsing

MCE ART.039 Distilled Deionised Water is a technical-grade fluid essential for critical interventions on motherboards. Unlike standard demineralised water, it undergoes rigorous treatment through distillation and ion-exchange resins. This process removes almost all minerals and dissolved salts, ensuring a chemically neutral and non-conductive liquid, ideal for restoring the surface impedance of a circuit after liquid immersion.

Technical Specifications

• Manufacturer reference: ART.039
• Volume: 500 ml (handy format for the workstation).
• Technology: High-purity distilled and deionised water.
• Compatibility: Printed circuit boards (PCBs), FPC connectors, sensors and optics.
• Properties: Total absence of mineral salts and conductive ions, neutral pH.
• Action: Intermediate rinsing, removal of detergent residues and decontamination.

Benefits for the Technician

• Residue removal: Its exceptional purity dissolves and flushes out deoxidation additives without leaving limescale or mineral deposits on BGA components.
• Targeted application: The precision spray allows the jet to be directed under shields or integrated circuits to dislodge pollutants in hard-to-reach areas.
• Neutral diluent: Perfect for diluting your enzymatic cleaning concentrates without causing undesirable reactions with ions naturally present in untreated water.

Safety precautions and workshop protocol

Deionised water must never be the final step of cleaning. It is imperative to follow the expert protocol: after thorough rinsing with ART.039, perform a final rinse with a hydrophobic solvent (Isopropanol or ART.031) to displace water molecules trapped under components. Stagnant water under circuits can cause fatal re-oxidation when power is reapplied. Keep the bottle tightly closed in your workshop to preserve its ionic neutrality.

???? Pro tip: Use ART.039 immediately after removing from the ultrasonic cleaner. Its jet pressure allows you to "push" soap and loosened impurities off the motherboard before they dry, greatly facilitating the final alcohol dehydration step at your repair station.
