Removing Perfume Scents From Sea Shells

Seashells are a wonderful memento of a day at the beach, but they can often retain an unpleasant odour. This is due to the organic matter that was once housed inside the shell. There are several methods to remove this smell, including soaking the shells in a diluted bleach solution, a process that can take several days. Alternatively, a mixture of water and glue can be applied to the shell, which dries invisibly and seals the shell against moisture.

Removing Perfume Smell from Sea Shells

Soak shells in a water and bleach solution

Soaking shells in a water and bleach solution is an effective way to remove unwanted odours. This method can be used to eliminate the "kiss of death" smell that sometimes emanates from shells due to the disintegration of the animal inside.

To start the process, create a bleach-water mixture. While some sources recommend a 50/50 solution, others suggest a ratio of one part bleach to nine parts water. The latter is more suitable for very dirty shells with a lot of heavy external matter. If you are unsure about the ratio, it is better to err on the side of caution and use a lower concentration of bleach, as the shell may absorb the bleach smell.

Once you have prepared the solution, fully submerge the shells in a bucket or bowl. Ensure that the shells are completely filled with the solution by giving the container a gentle shake to remove any air bubbles. The length of time you should leave the shells to soak depends on their type and number. For heavily soiled shells, you can soak them for up to an hour or even overnight. However, it is recommended to check on the shells approximately every other day to prevent them from absorbing the bleach smell.

After bleaching, thoroughly rinse the shells with tap water to remove any remaining bleach, dirt, or grit. Finally, allow the shells to air dry. If possible, place them outside in direct sunlight to enhance the drying process and help eliminate any lingering odours.

While this method is effective, it may take several iterations to completely eliminate strong odours. Additionally, some people prefer to avoid bleaching altogether due to the potential for discolouration and the risk of the shell absorbing the bleach smell.

Use a glue and water mixture to coat the shells

To get perfume smell out of seashells, you can use a glue and water mixture to coat the shells. This method is particularly useful for protecting clean, dry sand dollars and urchins. The glue used should be a white glue, such as Elmer's Glue-All or Sobo Glue, mixed with water in a ratio of 1 part glue to 9 parts water.

To apply the mixture, use a small paintbrush to coat the shells. If you have a large number of shells, you can let them soak in the mixture overnight. After coating, place the shells on wax paper to dry in the sun. Once the first side is dry, turn them over and coat the other side, allowing it to dry as well.

This method not only helps to seal the shells against moisture and strengthen them, but it also restores their original shine. It is important to note that this process may need to be repeated several times to completely eliminate the perfume smell from the shells.

While the glue and water mixture is effective, there are also other types of glue that can be used for seashell crafts, such as E6000, Gorilla Glue, and Beacon Sea Shell Glue. These glues are known for their strong adhesive properties and can be used to attach shells to various surfaces or to repair broken shells.

Soak shells in alcohol

Soaking shells in alcohol is an effective way to remove unwanted odours. If you're looking to get rid of a strong perfume smell from your shells, this method can help neutralise the scent.

First, it's important to identify the type of shell you're dealing with. For larger shells, such as bivalves, you'll want to soak them overnight. Smaller, snail-like gastropod shells should be soaked for a few days. This longer soaking time ensures that the alcohol penetrates the intricate curves and crevices of these shells.

When preparing the alcohol solution, it's best to use "rubbing alcohol" from a pharmacy. Aim for a higher concentration, such as 90%, as this will be more effective than a 70% solution. Before soaking, check the shells for any remaining soft tissues or organisms, as these can be a source of odour. Remove any visible matter with a thin, sharp tool.

Completely submerge the shells in the alcohol solution. If necessary, use a bucket or a container large enough to accommodate all the shells. Allow them to soak for the recommended time, then rinse and dry them thoroughly. After this process, the perfume smell should be significantly reduced or eliminated.

In addition to alcohol, there are other methods to remove odours from shells. Soaking in a bleach and water solution is a common approach, although some prefer to avoid bleach due to its harshness. Alternatively, a natural approach involves using a seawater soak before removing the shells from the beach, ensuring that any critters have vacated the shells.

Boil or freeze shells

Boiling and freezing are two methods that can be used to clean seashells and remove any animal tissue from inside the shell. However, it is important to note that these methods may cause the shells to crack, especially if the shell is still inhabited by an animal.

To boil shells, place them in a pot of room-temperature water, ensuring that they are completely submerged with about 2 inches (5 cm) of extra water. Bring the water to a boil and let it continue boiling for around 5 minutes, adding extra time if you are boiling multiple or larger shells. Then, use tongs to remove the shells from the water, placing them on a soft surface like a towel. Once cool, use tweezers or a similar tool to gently remove any remaining tissue from the shell.

Freezing shells is another option, and this method kills any remaining animal tissue inside, making it easier to remove. Place the shells in a Ziplock bag and put them in the freezer for at least one day, preferably 2-3 days. After removing the shells from the freezer, let them thaw slowly at room temperature. Do not place them in hot water, boiling water, or direct sunlight as this can damage the shells. Once thawed, carefully remove the animal tissue from inside the shells using a thin, sharp tool.

After using either of these methods, you can further clean and deodorize the shells by soaking them in a solution of bleach and water. The ratio of bleach to water may vary, with some sources recommending a 50:50 solution, while others suggest a more diluted mixture of 1 part bleach to 9 parts water. Soak the shells for several hours or overnight, then rinse them thoroughly under fresh water.

In addition to boiling or freezing, there are other methods to clean and deodorize seashells. Soaking the shells in alcohol or formalin (formaldehyde solution) can help to eliminate odors, and a mixture of white glue and water can be brushed or sprayed on to seal the shell and prevent moisture.

Soaking shells in hydrogen peroxide

Step 1: Prepare the Hydrogen Peroxide Solution

Mix equal parts hydrogen peroxide and water in a container. For a stronger cleaning solution, you can add laundry detergent or baking soda to the mix. If you are using a concentrated form of hydrogen peroxide (3%), dilute it with twice the amount of water.

Step 2: Submerge the Shells

Completely submerge the seashells in the hydrogen peroxide solution. Ensure that the shells are fully covered by the liquid. You may need to adjust the amounts of hydrogen peroxide and water based on the number of shells you are treating.

Step 3: Soaking Time

Allow the shells to soak for at least 15 minutes, and up to 30 minutes if the smell is strong. For heavily soiled shells, you can extend the soaking time up to an hour. Leave the shells undisturbed during this process to ensure all odors are removed.

Step 4: Rinse and Dry

After soaking, remove the shells from the solution and rinse them thoroughly with tap water. Dry the shells completely before handling or storing them. Place them in a well-ventilated area or under the sun to speed up the drying process.

Additional Tips:

• If the perfume smell persists, you can repeat the process or try a bleach and water solution as an alternative method.
• For delicate shells, a brief soaking time of around 10 minutes is recommended to avoid any potential discoloration or damage.
• Always handle hydrogen peroxide with care and avoid mixing it with household ammonia, chlorine bleach, or vinegar in a closed container, as dangerous gases can form.

By following these steps, you can effectively remove perfume smells from seashells using hydrogen peroxide, leaving them clean, sterilized, and odor-free.
