Glass cleaner is defined by its labelled purpose. Formulas vary and may contain alcohol, isopropanol, ammonia or other ingredients, so the complete original label is the authority.
How to identify it
Accept only an intact original container clearly labelled glass cleaner, window cleaner or an equivalent glass use. Never guess from blue liquid, a clear bottle or a trigger sprayer.
Common confusion
This item
Glass Cleaner
Original label explicitly states glass use
Label gives directions, warnings and compatible surfaces
Glass cleaner and kitchen degreaser may both come in trigger bottles; only the original label establishes identity and compatible surfaces. Distinguish glass cleaner from floor cleaner only by the original surface and compatibility label; bottle colour and shape are not reliable clues.
Common Hong Kong household uses
Clean glass as directed. Use on mirrors, stainless steel or other surfaces only when the label explicitly permits it.
Use & label checks
Read the original label for ingredients, surfaces, dose, contact time, protection and ventilation. Open windows or ventilate, keep away from ignition sources and patch-test an inconspicuous area.
Safe storage
Keep closed in its original labelled container, upright in a cool ventilated place away from sunlight, heat, food and children.
What Ma’am or Sir may say
用玻璃清潔劑之前先睇標籤,開窗,唔好溝漂白水。
