Having a touchscreen HVAC control panel in your car might look cool, but the touchscreen is vulnerable to accidental scratches too.
One day after a car wash, I found an obstructive scratch on my car's touchscreen HVAC control panel.
How to remove the scratch line and restore the touchscreen surface to be as smooth as before? I found the German-made Polywatch scratch remover cream to be a good solution.
The Polywatch cream looks like toothpaste, and comes in tiny 5 grams volume. But that amount of cream is enough for it to be applied multiple times.
I think it is named as Polywatch because it is originally formulated to polish and remove scratches on watch surface. In fact, it can be used to remove fine line scratches on smooth glass, acrylic and plastic surfaces. It works especially well with plastic surface.
It can magically eliminate tiny scratches and restore the surface to be as smooth as before. However, it might not work too well for deep scratches.
Polywatch works by slightly dissolving and grinding down the target surface to smooth the edges of the scratch and fill the gaps with the dissolved material, therefore restoring it to unscratch condition.
Using Polywatch is pretty easy. Just clean the target surface, make it dry and dust free, apply some Polywatch cream on the scratch, and polish it with a piece of microfibre cloth or cotton wool.
If you are facing similar problem of having obstructive scratches on glass, acrylic or plastic surfaces, you might give Polywatch a try.
