Sea glass is a type of glass that comes from the ocean. It is often found on beaches and in waterfalls. When it is clean, it looks like a clear glass. To clean sea glass, you will need to first remove any dirt and sand that has built up on it. Then, you will need to use a vacuum cleaner to remove all the cleaning material that was inside the glass. Finally, you will need to dry the sea glass completely before putting it back in its place.
