Acrylic - sometimes called plastic or perspex - is a hardwearing substance, but like anything if coming against pressure, it can scratch.
Don't worry, all you need to do now is follow the below steps to easily buff it out.
Firstly, you need to decipher whether the scratch is a light scratch, or a deep scratch as these steps will follow different procedure on how to remove.
- You will need to use wet and dry sandpaper, around 800 grit to be precise, wet this and rub the scratch in a circular motion, until it becomes hard to see. Keep the sandpaper just wet enough so that a slight slurry forms.
- Then use a less coarse wet and dry, about 1200 grit, and use in the same way until scratches are no longer visible.
- Wipe the area clean with a soft cloth, the area may now be visibly more dull than the rest of the acrylic. To bring it back to life simply rub with metal polish for example, Brasso.
You will simply need to use a more coarse sandpaper to start with, about 600 grit, before continuing with steps 2 and 3 above.
