Just want to share again. Scratches were deep so toothpaste alone wasn't able to do the job.
My tools :
Sand paper 1200 grit.
Old Toothbrush optional to sweep away acrylic dust.
One very important thing to consider - after sanding, the acrylic feel smooth but will look dull. If you wipe it with a wet cloth, the dullness will disappear for a few seconds and then come back. This is where the toothpaste and towel come in. Place towel on table. Apply a pea size amount of toothpaste on towel. Hold watch with dial/acrylic crystal face down, press it against the toothpaste that is on the towel, then move it back and forth. The added weight of your hand and forearm makes the polishing more efficient and effective.
1. What exactly does polishing with toothpaste does? Or rather how is it able to make the acrylic clear again after sanding? I don't quite understand the principle.
2. Is this method effective with mineral glass too?
Now for the pics! First two pics are the before, then third and fourth are the after.
Don't forget to answer my two questions please. Thanks much!
