Bleaching, sanding, and a coat of oil give clamshells a polished look for crafts.

Before using a clam shell in a craft project, polish the shell to make it stand out. Clam shells found on the beach need to be cleaned and bleached prior to polishing, while shells you purchase at the craft store typically have been bleached already.

Step 5

Sand the shells gently, using light sandpaper, until glossy and smooth

Step 6

Pour mineral oil on a soft cloth and polish each shell until it shines.

Some crafters polish their clam shells with clear nail polish or use WD40 instead of mineral oil.

Warning

Do not use vegetable oil or baby oil to polish the clam shells, as they will eventually become rancid and develop an unpleasant smell.
