Important characteristics of cleaning products

Consequences, especially with flat screens

Dissolved with (regular) water

Dull / less bright screens – gradual ‘chalking’ of the coatings – Irrepairable

Chemical, sour and/or alcohol components to dissolve dirt.

Damaging / destroying of the sensitive coatings. Characteristic: ‘holes’/ scratches and or stripes over the screen: Irrepairable.

High conductivity / low resistance (almost all products)

Corrosion / short circuit (especially flat screens have the risk of ‘incoming’ moisture) Characteristic: partial or complete screen fall out. Irrepairable.

No components to protect the cleaned surfaces

Faster filthiness than without cleaning. Aging of coatings. Characteristics: too filthy to clean, yellowing; hair scratches.

Other damages of flat screens

Reason / Solution

Pixel fall out (various pictures or rows (often fixed  patterns) and/or short circuit.

Except for out-of-box failures = warranty claim, caused by cleaning with unsuited product (see above)

Finger / thumb / hand prints (often larger areas with stripes – irregular)

Except when it is ‘greasy’, most often caused by too hard pushing on the screen (handling but also cleaning) causing damages to the underlying structures: irrepairable.

Finger prints (other than greasy – cannot be removed)

Touching of the screen with dirty fingers which damage a coating. Coating dissolves partially locally. Irrepairable.
