To bring back the shine to your sea glass, simply rub a little amount of food grade/cosmetic oil (olive oil is fine) over the glass using your finger or clean cloth.

Mix equal parts of white vinegar and water and soak the sea glass in the solution for a few hours. Then, use a soft-bristled brush to gently scrub away any dirt or debris. Rinse the sea glass with clean water and let it air dry.

Filling a spray bottle with some undiluted white vinegar is a great, fuss-free way to clean windows. Working your way from the top of the glass to the bottom, saturate the whole window surface with the vinegar. Once the window is covered, let it rest for 5-10 minutes so the vinegar has time to dissolve the salt scum.
