Distilled water is "ultra-pure water" obtained by evaporating and then condensing water using a water distiller . Because it removes almost all minerals, impurities, and microorganisms from tap water, it is indispensable in many situations requiring high precision and cleanliness.

Here are some of the main uses of distilled water in daily work and life:

1. The "Guardian Angel" of Dental Sterilization Equipment

This is the most crucial use of distilled water in clinics.
Prevents scaling: If tap water is used in autoclaves, the calcium and magnesium ions will quickly turn into hard scale at high temperatures, clogging the small pipes inside the machine like blocked blood vessels. Using water produced by a water distiller keeps the inside of the machine sparkling clean.
Extends instrument lifespan: Impure water, after high-temperature evaporation, will leave unsightly white spots on expensive dental handpieces and forceps, and can even cause chemical reactions leading to metal rusting. Distilled water leaves no traces and protects the precision of the tools.

2. Ensuring the Performance of Precision Instruments

Besides sterilizers, many precision instruments in laboratories and clinics also have strict requirements for water quality.
Chemical experiments and testing: When preparing some special reagents or conducting tests, even a tiny amount of impurity in the water can affect the final results. Using water produced by a water distiller ensures a "zero-pollution" experimental environment.
Ultrasonic cleaning machines: When cleaning small precision parts, distilled water can work with cleaning agents to achieve better penetration, and will not leave a mineral film on the surface of the parts after cleaning.

3. The "Secret to Longevity" for Household Appliances

In daily life, distilled water is also a "cure" for many small household appliances.
Garment steamers and irons: Many people find that their irons spray white powder after prolonged use; this is the culprit left by tap water. By switching to distilled water, the steam vents will never clog, and no unsightly marks will be left on clothes.
Humidifiers: Ordinary water sprayed from a humidifier will form "white powder" scattered on furniture, while the mist from distilled water is the purest and more friendly to the respiratory tract.

4. Car Batteries and Cooling Systems

Battery Fluid Refill: If an older car battery is low on fluid, distilled water must be added. Adding tap water will introduce minerals that will disrupt the battery's chemical balance and cause it to fail prematurely.
Coolant Dilution: When mixing engine coolant, using water treated by a water distiller prevents scale buildup inside the radiator, ensuring smooth engine cooling.

5. Personal Care and Special Hydration Needs

CPAP Machine Humidification: For people who need to wear a CPAP machine for sleep apnea, distilled water must be used in the humidifier tank to prevent inhaling mineral deposits and maintain the machine's internal hygiene.
Mixing Beauty Products: Many people prefer to use distilled water when mixing homemade face masks or skincare products because it is pure enough not to cause additional irritation to sensitive skin.
