This is a product file, not a new-product announcement or performance ranking. The protected operations snapshot dated 14 September 2026 confirms that EPHYON Glass Polish is published, has a net content of 500 g and is a liquid dosage form; the formal page provides the product entry point. This article stays within those verified boundaries and does not turn page wording into test results or a universal material promise.

Glass, ceramics, appliance housings, televisions and computer screens may all look smooth, but their substrates, coatings, seals and cleaning restrictions differ. Identify the object first, then read its manufacturer instructions and the current cleaner label. Judging compatibility merely because a surface shines or “is glass” can overlook screen coatings, openings and electrical-safety boundaries.

The EPHYON page lists spraying followed by wiping with a dry cotton cloth and mentions glass, ceramics, appliances, furniture, television and computer screens. This is a brand-page statement, not an independent same-condition test. If a device maker requires water only, liquid applied to the cloth only, or prohibits household glass cleaner, the exact device instructions take priority.

Apple advises disconnecting external power and cables, using a soft lint-free cloth, preventing moisture from entering openings and not spraying cleaners directly onto a device. It also states that requirements differ by Apple product and material. This supports the order “follow the device instructions first”; it does not mean Apple evaluates or endorses EPHYON products.

Samsung’s television guidance similarly recommends switching off power and starting with a soft, dry microfiber cloth. If moisture is needed, water goes on the cloth rather than directly on the panel, and window cleaners, soap and other unsuitable chemicals should be avoided. This is Samsung television-care guidance and cannot establish that every screen uses the same material.

LG’s screen-cleaning guidance also prioritises disconnection, a soft microfiber cloth, a small amount of water and gentle wiping, with the cloth nearly dry. The page shows that display manufacturers may set narrower limits than those for ordinary glass. It is not a brand-performance comparison and does not prove one cleaner suits every LG model.

Dell’s product-use document recommends a soft clean cloth and water for displays, monitors, LCD screens or televisions. Read together, the device-maker instructions support a restrained conclusion: routines for architectural glass should not be transferred directly to coated electronics or devices with openings, and model-specific instructions belong in the pre-use check.

Use a four-step check: identify the material and model; read the object manufacturer’s cleaning instructions; read the current product label and its exclusions; and, if both allow it, check a small inconspicuous area while keeping liquid away from gaps. If either instruction prohibits spraying or a cleaner category, the word “glass” in the product name does not override that restriction.

Boundary: the protected product record currently has an empty claims array. This article therefore does not repeat or expand “antistatic,” “dust-resistant” or “no water marks” as performance guarantees, and makes no antibacterial, hypoallergenic, environmental, food-contact, all-material or firsthand-test claim. Use, method, exclusions and performance wording remain subject to the complete current label, valid test evidence and the object manufacturer’s instructions.
