When you make handmade decorative accents for your home, you can end up spending a lot of money at a craft-supply store on the materials for your project. For example, you may buy bleached oyster shells for a beach-themed home accessory. Instead of buying pre-bleached oyster shells, bleach your own oyster shells using a few basic materials that can be purchased inexpensively from a supermarket. This enables you to make beachy home accents on less money.

Things You'll Need

  • Rubber gloves
  • 2 buckets, 10 gallon
  • Bleach, unscented
  • Long-handled spoon
  • Towel

Put on rubber gloves to protect your skin from the bleach water.

Fill a 10 gallon bucket halfway full of water.

Pour 1 cup of unscented bleach into the water. Stir the solution for 1 minute using a long-handled spoon.

Place up to 2 lbs. of oyster shells into the bleach water and push the shells under the water using the long-handled spoon. Allow the shells to remain in the bleach water for 30 minutes.

Rinse off the bleached oyster shells under clear water for 2 minutes, then lay the shells onto a towel to air dry for 3 hours.

Tips & Warnings

  • Keep bleach out of the reach of children.
