1. Cleaning: First, you can try to put the duvet core into the washing machine, choose a special duvet cleaning program, add laundry detergent and a little vinegar, and be sure to choose cold water to clean it. After washing, prevent it from being exposed to the sun and dry it naturally.
2. Strong deodorant: Another option is to use special strong deodorant to remove the smell. These products can be found in supermarkets or pet shops. Before use, please spray it on the duvet core according to the instructions in the manual and dry it in a ventilated place.
3. Plants remove the smell: Some plants also help to remove the smell. For example, put crushed lemon or orange peel, tea leaves, etc. into a cloth bag and put it on the duvet core for several hours to eliminate the smell.
4. Store separately: If your cat often sleeps with your duvet, which may leave a smell on the duvet core, store the duvet core separately for a period of time until the cat's smell dissipates.
In a word, cleaning and deodorizing agents are the most commonly used methods, but please pay attention to the selection of appropriate cleaning methods to ensure that the quality of duvet cores will not be affected.
