How to clean and polish shells properly – here’s how it works

Cleaning shells: A simple guide

 Shells are often covered in dirt, algae, or animal remains. To clean them, proceed as follows:

1. Place the collected seashells in a container, such as a bucket. When collecting them, make sure that there are no living creatures left in or between the shells.
2. Cover the shells completely with water. Leave the shells to soak for a week to make cleaning easier. Change the water every day.
3. After the waiting period, boil the shells in fresh water for five to ten minutes. Then drain them using a sieve.
4. Use a toothbrush to remove any tissue residue and barnacles. Scrub the mussel shells thoroughly. Finally, rinse them again with clean water.
5. Note: Thin shells should only be placed in hot water for a short time and should not be boiled. Otherwise, they may become brittle.

1. Baby oil, low-odor vegetable oil, or something similar is best for polishing. Apply a sufficient amount to the shells and rub it in thoroughly.
2. Use your fingers to do this. Alternatively, use a lint-free cloth, a cotton swab, or a soft toothbrush if the areas are difficult to reach.
3. Then carefully dry the shells.

   Wait until the oil has been completely absorbed before using the shells for crafting.

4. Tip: For extra shine, you can paint the shells with clear varnish.

More tips for cleaning shells

 To use shells as decoration and craft materials, avoid damaging them. The following tips will help:

• Do not use bleach when soaking. Although this can be effective against dirt, it makes the shells brittle.
• The shells often absorb the smell of the bleach, which is usually undesirable.
• Instead, you can use baking soda or baking powder. Make a paste with water and rub it onto the shells. Don’t forget to rinse them off.
• Some shells still smell strongly even after cleaning. Place the clean shells in the sun for a few hours or wipe them with vinegar or citric acid.
