Step 1: Mix Baking Soda
Pour the baking soda into the bowl and add a splash of water. Then stir everything vigorously with the spoon. The liquid should solidify after a short time.

Step 2: Apply to the Display Scratches

Step 3: Wipe the Display and Check for Scratches
Simply wipe away the excess foam with the cloth. The display should be not only clean but also free of micro-scratches. However, this trick does not work for larger scratches.

Protect the Display from Scratches Afterwards
To avoid getting new small scratches on the display afterward, a protective film is recommended. These so-called armored films are available for around ten euros for all current models online. The necessary tools for application are included, but you’ll need a steady hand. If in doubt, get help.

If you want to be extra cautious, you can also get a flip cover. This encloses the smartphone from the back and covers the display with a flap element. Although these covers protect the display and the entire phone very well from scratches, they compromise aesthetics. The smartphone’s design is no longer visible. The flip cover can also interfere with photography.
