Step-by-Step Instructions

Step 1: Safety First

Before you begin, make sure you are wearing protective eyewear and gloves. Sanding glass can produce small shards, and safety should always be your top priority.

Step 2: Prepare the Glass

Clean the glass with water and a mild detergent to remove any dirt or grime. Pat it dry with a soft cloth.

Start with a coarse grit sandpaper, such as 80-grit. Wet the sandpaper with water and gently sand the glass in circular motions. Apply even pressure and avoid pressing too hard.

Step 4: Progress to Finer Grit

Gradually move to finer grit sandpaper, such as 150-grit and then 220-grit. Repeat the circular motions, constantly wetting the sandpaper. This will create a smooth finish.
