As an expert in the field of materials and restoration, I often encounter questions about how to maintain and restore various surfaces, including acrylic. Acrylic, being a versatile material, is used in a wide range of applications from furniture to artwork. However, it can be prone to scratches, which can detract from its appearance. Fortunately, there are methods to remove or minimize the visibility of these scratches.

Step 1: Light Scratches
For light scratches, you'll need some 800 and 1200 grit wet and dry paper, and some metal polish (Brasso works well). Begin by dampening the area you want to work on with water. Then, fold the 800 grit sandpaper and gently rub it in a circular motion over the scratched area. This process should be done with enough water to keep the sandpaper moist and to create a slight slurry, which helps in smoothing out the surface. The circular motion is crucial as it helps to evenly distribute the sanding action and prevent further damage to the acrylic.

Step 2: Deeper Scratches
If the scratches are deeper, you may need to start with a lower grit sandpaper, such as 400 or 600 grit, before moving to the 800 grit. Always begin with the lowest grit necessary to avoid removing too much material. After using the lower grit, rinse the area thoroughly and then proceed with the 800 grit as described above.

Step 3: Polishing
Once the scratches are less visible, you can move on to polishing. Apply a small amount of metal polish to a soft cloth and gently rub it over the area in a circular motion. This will help to restore the shine and further minimize the appearance of any remaining scratches.

Step 4: Buffing
After polishing, use a clean, dry cloth to buff the area. This will remove any excess polish and give the acrylic a nice, even finish.

Step 5: Final Touches
For the final step, you may want to apply a plastic polish or a product specifically designed for acrylic surfaces. This will not only protect the surface but also enhance its shine.

Precautions
- Always test a small, inconspicuous area first to ensure that the sanding and polishing process does not discolor or damage the acrylic.
- Be patient and work slowly to avoid causing more harm than good.
- Ensure good ventilation when using polishes and work in a well-lit area to accurately see the progress of your work.

By following these steps, you should be able to significantly reduce the appearance of scratches on acrylic surfaces, restoring their original luster and clarity.

So, first off light scratches: You will need some 800 and 1200 grit wet and dry paper, and some metal polish (Brasso works well). Fold the 800 grit and using water rub in a circular motion until most of the noticeable scratches become hard to see. Keep enough moisture on the paper so that a slight slurry forms.read more >>
