How to wash a dormitory mattress when it gets dirty

To clean the dormitory mattress, you can follow these steps:

1. Remove the cover: If the mattress cover can be taken off, it should be removed first. This will allow for easier cleaning of the internal structure.
2. External cleaning: For dust and other external dirt, use a vacuum cleaner for a thorough cleaning. Make sure the vacuum cleaner’s attachment is clean so that it can properly reach the surface of the mattress, especially into crevices and other hard-to-reach areas. 1234
3. Internal cleaning:
   For fresh blood stains, you can apply ginger to the stain, then wipe it with a cold wet cloth, and finally absorb any excess moisture with a dry cloth or paper towels. 24
   For old blood stains or other protein stains (such as sweat), you can use carrot juice mixed with a little salt or a stain remover prepared with hydrogen peroxide and detergent in a proportional mix. After treatment, wipe it clean with a cold wet cloth.
   For grease stains or tannin stains (such as juice or tea), specialized cleaning agents and methods should be used for removal. 4
4. Dry the mattress: After the external and internal cleaning is done, the mattress should be placed in the sun to dry, ensuring its dryness.
5. Regular turning: To maintain the comfort and lifespan of the mattress, it is recommended to turn it once every quarter, ensuring even wear on all parts of the mattress. 2
6. Use a protector pad: To prevent the mattress from sagging due to long-term use, consider using a mattress protector pad, which helps extend the mattress’s lifespan.
   Remember, when performing any cleaning work, use the least amount of cleaner possible, and ensure the mattress is completely dry after cleaning to prevent the growth of mold.
