This is the classic method that always works ! Mix one tablespoon of white vinegar with 5 parts hot water . Add a touch of dish soap . Dip an old toothbrush in it and gently scrub the seal, paying particular attention to the creases.
Are the nooks and crannies inaccessible? Slip a piece of absorbent paper around an old loyalty card (or bank card) and run it through the grooves. The result: a clean, effortless seal without harsh chemicals.
Tip 2: Baking soda for deep cleaning

Baking soda neutralizes unpleasant odors and cleans gently. Again, remember to wipe the narrowest creases with a card wrapped in absorbent paper . Then rinse with a damp cloth and dry thoroughly .
Tip 3: Household alcohol, for an express freshening boost

Bonus tip: A few drops of lemon or eucalyptus essential oil can be added for a pleasant touch of freshness .
And for tougher cases?

Once the treatment is complete, remember to rinse the seal and dry it to prevent moisture from settling back in.
