Glass cleaner
A product category built on fast evaporation rather than cleaning power — and the two ingredients that make it work are the two the mirror trade excludes.

- Never mix with other cleaning products
In detail
Glass cleaner is formulated around a problem most cleaning products do not have: whatever is left behind is visible. Its job is therefore to lift a light film and then disappear, which is why the typical formulation is mostly water with a volatile solvent, a trace of surfactant, and historically either ammonia or an acid to cut greasy and mineral films. That formulation is exactly what makes it the wrong bottle for a mirror. The glass industry's mirror guidance names vinegar and ammonia specifically among the cleaners not to use, because a mirror is not glass — it is glass with a reflective coating and a protective backing exposed at every cut edge, and acid and alkali attack them from opposite ends of the pH scale. On plain glazing the constraint is looser and the industry's own advice is a clean solution, a squeegee, and drying the edges. Two further limits apply everywhere. Glass cleaner is not a degreaser, so a hob splashback needs detergent first. And on a screen, one computer maker allows only a cleaner made for display surfaces, free of ammonia, applied to the cloth after its alcohol clean, never an ordinary window spray.

What works
Glass cleaner is safe on, in specific conditions, Extractor hood
Safe only in specific conditions
This is only appropriate within specific limits, and nothing is established outside them.
Only within these limits:
- Named for a porcelain hood surface specifically
- Not on stainless steel, fingerprint-resistant coatings or control panels, which the manufacturer files separately
An unusual permission: glass cleaner on an appliance body. The publisher states it for one finish and gives the other finishes their own separate articles.
Precautions
- Check the manufacturer's instructions

Glass cleaner is safe on, in specific conditions, Laptop screen
Safe only in specific conditions
This is only appropriate within specific limits, and nothing is established outside them.
Only within these limits:
- a glass cleaner designed for display surfaces, not a general window or mirror spray
- free of ammonia
- applied to the cloth and never sprayed onto the screen
- wiped in one direction, from the top of the display downwards
- used after the damp alcohol clean, as a second step rather than instead of it
Ordinary glass cleaners are usually the wrong bottle for a screen, and many contain the ammonia this manufacturer names. The permission is for a product made for displays, on this manufacturer's equipment.
Precautions
- Disconnect from the power supply first
- Check the manufacturer's instructions
