Step 1: Clean the Plexiglass

Start by cleaning the plexiglass surface with a dedicated plexiglass cleaner or a mixture of mild soap and water. Use a microfiber cloth to avoid further scratching while removing dust and debris.

Step 2: Assess the Scratches

Examine the depth and extent of the scratches. Light scratches can often be polished out, while deeper scratches may require more aggressive techniques.

Step 3: Wet Sanding (If Necessary)

If scratches are deep, consider wet sanding. Wet the fine-grit sandpaper and gently sand the scratched area in a circular motion. Keep the surface wet to minimize further scratching.

Step 4: Apply Acrylic Polish

After sanding, apply a small amount of acrylic polish to the scratched area. Use a soft buffing pad or buffing wheel to polish the area in a circular motion.

Step 5: Final Cleaning

Once the scratches are minimized or removed, clean the area again with a plexiglass cleaner to remove any residue from the polish.

Step 6: Inspection

Inspect the surface under good lighting to ensure all scratches have been adequately addressed. Repeat the polishing process if necessary.
