I'm very sorry for your loss. Preserving the scent of someone's pheromones in clothing can hold sentimental value as a way to remember them. While there's no foolproof method to retain the exact scent of an individual's pheromones indefinitely, you can try the following steps to help prolong the scent for some time:
Seal the Clothing: Place the clothing items in an airtight container or a vacuum-sealed bag. This can help trap the scent and prevent it from dissipating quickly.
Store in a Cool, Dark Place: Keep the sealed container in a cool, dark place. Avoid exposure to direct sunlight or extreme temperature changes, as they can cause the scent to degrade faster.
Add a Scented Item: If you wish, you can place a scented item in the container with the clothing, such as a sachet of dried lavender or a few drops of essential oil on a cotton ball. However, be cautious not to let the scented item come into direct contact with the clothes, as it may transfer and alter the original scent.
Use Silica Gel Packs: Silica gel packs can help absorb excess moisture, which could potentially damage the fabric or cause odors to develop. They can be found in various products, such as shoeboxes or electronic packaging, and can be reused after being reactivated.
Handle with Care: Avoid excessive handling of the clothing, as the oils and dirt on your hands could transfer to the fabric and alter the scent.
Please be aware that scents will naturally fade over time, and there's no guarantee that the scent of pheromones will remain for an extended period. Memories can be precious, and while the scent may diminish, the emotional connection and memories you have of your spouse will endure.
If you find it challenging to cope with grief, consider seeking support from friends, family, or a professional counselor who can provide comfort and guidance during this difficult time.
