How To Get Bad Fish Smells Out Of Seashells

Searching for seashells is a standard part of any seaside vacation, but finding a pretty shell with a putrid fish odor quickly turns this delightful pastime into a disappointment. However, don't be so quick to throw that seashell back in the sea; you can clean it at home with ingredients you may already have on hand.

Something's Fishy

If your seashell has a fishy odor, chances are that a dead creature is inside the shell. Use one of two methods for the dead creature removal: One involves boiling, and the other calls for freezing.

Things Needed

  • Salt

  • Baking soda

  • Shallow dish

  • Plastic bag

1. Boiling

  • Boil empty shells in water for a few minutes.

Tip

The boiling method may cause your kitchen to smell, so be sure to open your windows when you boil the shells.

2. Freezing

  • Create
    a drying solution made of 1 part of baking soda and 3 parts of
    salt in a shallow dish. Generously coat and fill each shell with the
    solution and place with the other shells in a plastic bag.
  • Place
    the bag in the freezer and freeze until the smells are gone.

Tip

Brittle shells require a different cleaning method. Place them in a container of silica gel to dry and allow the dead tissue to mummify.

Warning

Be aware that the state in which you are collecting shells may have regulations concerning the harvesting of shells. Play it safe and leave any shells with live organisms on the beach.

Clean the Shell

After the fish odors have been removed, it's time to clean the exterior of your seashells. Create separate piles of shells, taking care to divide sturdy shells from fragile specimens, bivalves and iridescent shells. Each type of shell needs different cleaning methods.

Things Needed

  • Bleach

  • Warm water

  • Dish soap

  • Big container

  • Soft-bristled toothbrush

  • Towels

1. Cleaning sturdy shells:

  • Mix 4 cups of bleach, 4 cups of warm water and 1 tablespoon of
    dish soap in a large container.
  • Add
    the sturdy seashells to the container and allow them to soak.
  • After
    soaking for a half-hour, use an old toothbrush to scrub off the
    barnacles, seaweed and other debris.
  • Once
    the seashells are thoroughly cleaned, rinse and let them air-dry on a
    towel.

2. Cleaning fragile, iridescent and bivalves:

  • Mix
    mild dish soap with warm water in a large container.
  • Place
    the shells in the container and wash with an old soft-bristled
    toothbrush.
  • Once
    thoroughly cleaned, rinse and let air-dry on a towel.

Tip

Keep your seashells looking shiny by brushing mineral oil or baby oil on them.

Warning

Never soak seashells in vinegar. Vinegar is an acid that dissolves calcium carbonate, the primary component of all seashells.
