Mobile phone
The most-handled object anyone owns, and the manufacturer's guidance stops at glass, ceramic and metal — which leaves the case and the charging port outside it.
What not to do
Sodium hypochlorite (chlorine bleach) is unsafe on Mobile phone
Unsafe
Do not do this. The risk is established, and it is described below.
Why we say this
Supported
A manufacturer prohibition stated by name.

In detail
A phone is cleaned more often than anything else in this catalogue and its manufacturer guidance is narrower than the question people ask. Preparation is three steps: power it down, take the case off, unplug everything. The cloth is soft, lint-free microfibre — a camera lens cloth is the example given. The permitted solutions are named with concentrations, which is unusual and useful: distilled water, or a disinfectant that is either hypochlorous-acid based at 50 to 80 ppm or alcohol-based at MORE THAN 70% ethanol or isopropyl alcohol. Only the CORNERS of the cloth are dampened. The phone is wiped gently, front and back, without much pressure, and excessive wiping is itself discouraged. The prohibitions are where it gets interesting. No moisture in any opening. Never apply liquid directly to the phone. Never spray bleach or any solution onto it. And DO NOT USE COMPRESSED AIR — which is the single most recommended technique in consumer articles about charging ports. The scope is the part most often lost when this is repeated. The guidance covers the GLASS, CERAMIC AND METAL surfaces of the phone.
What works
Isopropyl alcohol is safe on, in specific conditions, Mobile phone
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, CleaningHQ makes no claim.
The second device manufacturer in this register to clear alcohol above 70% on a hard non-porous surface, and it still says nothing about a coated spectacle lens.
Only within these limits:
- more than 70% isopropyl alcohol or ethanol, per the manufacturer
- applied to the CORNERS of a soft lint-free microfibre cloth, never to the phone
- phone powered down, case removed and cables unplugged first
- glass, ceramic and metal surfaces only - not leather, rubber or plastic accessories
- no moisture into any opening, and no excessive wiping
Precautions
- Disconnect from the power supply first
- Check the manufacturer's instructions
Why we say this
Supported
Two manufacturers in different device categories agreeing on the agent and on the application method. The conditions are the clearance; the concentration alone is not.
