AC/DC Power Adapter Can it be disinfected with alcohol? The manufacturer explains the correct cleaning method

AC/DC Power Adapter Can it be disinfected with alcohol? UNIFIVE, the manufacturer, explains which disinfectants can and cannot be used, along with the correct cleaning procedures. We also introduce Products suitable for environments that require frequent disinfection, such as medical settings and factories.

With the recent increase in hygiene awareness, there is growing demand not only to disinfect and clean PCs and monitors, but also peripheral devices such as AC/DC Power Adapter and chargers on a regular basis.

In particular, medical and nursing care facilities may be required to carry out regular disinfection, including peripheral devices of medical equipment, as part of infection control measures. In addition, food factories and commercial kitchens require daily cleaning to meet hygiene standards. Furthermore, in office environments where an unspecified number of people touch shared desks and coworking spaces, disinfecting power adapters has become an important issue.

However, disinfecting precision equipment such as AC/DC Power Adapter using incorrect methods may cause malfunctions, short circuits, or material deterioration.

This article clearly explains safe and effective cleaning and disinfection methods based on the expertise of UNIFIVE, an AC/DC Power Adapter manufacturer.

1. Compatibility Between UNIFIVE AC/DC Power Adapter and Alcohol

In conclusion, UNIFIVE AC/DC Power Adapter can be disinfected with alcohol.

The reason lies in the material used for the enclosure (case) of the Products. Our representative Products (such as the UB310-0520) use polycarbonate (PC), a plastic material with excellent impact resistance and chemical resistance, for the case.

[Key Point] Differences Depending on Material

Some low-cost commercially available AC/DC Power Adapter use ABS resin. ABS resin has lower resistance to alcohol than polycarbonate, and repeated use may cause surface cracks (chemical cracks). It is important to check the adapter material before disinfecting.

Disinfecting Ethanol (Ethyl Alcohol)

It does not damage PC material or metal parts and can be used safely.

Isopropyl Alcohol (IPA)

Similarly, it does not affect PC material or metal terminals. IPA is widely used for cleaning electronic devices and has the advantage of fast drying due to its high volatility.

High-Concentration Alcohol

Even when using a high-concentration disinfectant close to 100%, we have determined that there is no effect on the AC/DC Power Adapter itself. However, from the perspective of disinfection effectiveness, a concentration of around 70-80% is considered most effective, so excessively high concentrations are not necessary.

[Caution] Methyl Alcohol (Methanol) Cannot Be Used

Although it is also called "alcohol," methyl alcohol (methanol) is highly corrosive to polycarbonate and cannot be used. When purchasing disinfectant, check the ingredient label to ensure it is ethanol or isopropyl alcohol (IPA). See the next section for details.

2. Disinfectants to Absolutely Avoid

Caution is required when using chemicals other than alcohol. The following agents may cause malfunction or accelerate material deterioration of AC/DC Power Adapter.

x Hypochlorous Acid / Chlorine-Based Disinfectants

These have strong corrosive properties against PC material, causing discoloration and degradation of the case. If they adhere to metal parts such as USB terminals or DC plugs, they can cause rust (corrosion) of the metal frame. Do not use chlorine-based Products such as bleach.

x Methyl Alcohol (Methanol)

Although it is also an "alcohol," methyl alcohol (methanol) has strong corrosive properties against polycarbonate (PC). It can cause whitening and cracking (chemical cracks) on the case surface, so never use it. Its properties differ from disinfecting ethanol and isopropyl alcohol (IPA), so always check the ingredient label when purchasing.

x Thinners (Acetone, Xylene, Toluene, Benzene, Methyl Ethyl Ketone, etc.), Benzine and Other Organic Solvents, Abrasives

"Thinner" is a generic term, and the impact on PC material varies depending on the solvent components. In particular, acetone, xylene, toluene, benzene, and methyl ethyl ketone (MEK) have extremely strong corrosive effects on polycarbonate and can cause dissolution and cracking (chemical cracks) of the case. Benzine and other organic solvents, as well as abrasives, may also damage plastic and must never be used. Do not use these agents to remove dirt or yellowing.

3. Proper Disinfection Procedure to Prevent Malfunctions (4 Steps)

To ensure long-term use of your AC/DC Power Adapter, always follow the steps below when cleaning and maintaining it.

Step 1: Unplug the Power

To prevent electric shock or internal short circuits, always unplug the AC/DC Power Adapter from the wall outlet and disconnect it from connected devices (PCs, monitors, etc.).

Step 2: Apply Disinfectant to a Cloth

Never spray directly onto the Products. Apply the disinfectant to a soft, lint-free cloth such as microfiber, wring it lightly so it does not drip, and then use it.

Step 3: Gently Wipe the Main Unit

Wipe the entire surface of the case evenly. Be careful to prevent liquid from entering connector terminals or gaps in the enclosure. Clean terminal areas only lightly with a dry cotton swab.

Step 4: Allow to Dry Completely

After disinfection, allow it to air dry thoroughly. Connecting to power while moisture remains may cause malfunction, so ensure no liquid remains on the surface before reconnecting.
