Wear rubber gloves while cleaning to protect your hands from the chemicals. Use only a clean soft cloth, rather than one of your sponges that already has cleaning products on it. Allow the surface to dry before continuing to the next step.
If the scratch is still visible, progress to 800, 1000, and then 2000 grit. The higher the grit, the finer the sandpaper.
Use an electronic buffer to save time, and your arm. Apply the polish to the buffer pad. Keep your tool at a low setting, and apply even pressure. [2] X Research source
Wear new rubber gloves as you work to protect your hands from the chemicals. Avoid using old sponges or cleaning brushes. Use a new soft cloth to be sure you don’t scratch the aquarium surface, or mix cleaning products. Wait for the surface to dry before moving on to the next step.
You can also purchase buffing kits on hardware stores.
