Clean and remove small scratches:
You can remove small scratches from you screen with a pencil eraser, but it takes some time, so you have to be a bit patient.
Remove scratches from an iPad screen: materials
glass scratch remover polish (often used for display cases)
a microfibre cloth (available in every supermarket)
Method
First you should provide a soft surface to work on, to prevent further scratches.
Clean the display with a dust-free cloth on the front. This is best dome with a microfiber cloth. Under no circumstances may other fabrics or cloths be used! Only a microfiber cloth is gentle enough.
Now apply some of the polish to the display and polish the entire glass with the cloth for 3-4 minutes under strong pressure using a circular motions.
After that, the scratches should actually be history.
If not, for example with deep scratches, simply repeat the application several times until the desired result is achieved.
Do not use on painted surfaces, just work on the transparent display glass.
