Mold stains in books are not contagious in the sense that they can spread from one book to another. However, if a book with mold stains is stored in a damp or humid environment, the mold spores can spread and potentially affect other books in the same area. It's important to address mold stains in books promptly and store them in a dry, well-ventilated space to prevent the spread of mold. Regular cleaning and maintenance of the bookshelves and storage area can also help prevent the spread of mold. **

You can cover stains on the wall paint by first cleaning the area with a mild detergent and water to remove any dirt or grime. Once the area is clean and dry, you can use a primer to cover the stain before applying a fresh coat of paint. If the stain is particularly stubborn, you may need to use a stain-blocking primer to ensure that the stain does not bleed through the new paint. Additionally, choosing a paint color that closely matches the existing wall color will help to effectively cover the stain. **

Gently dab the concealer onto the stained area and blend it in using your fingertips or a makeup sponge.

If the stain is still visible, you can apply another layer of concealer and blend it in until the stain is fully covered. Finish by setting the area with a light dusting of translucent powder to ensure the concealer stays in place. **

To remove old grease and oil stains, start by blotting the stain with a clean cloth to absorb as much of the oil as possible. Then, sprinkle baking soda or cornstarch over the stain and let it sit for 15-20 minutes to absorb more of the grease.

If the stain persists, you can also try using a grease-fighting laundry detergent or a commercial stain remover. Always remember to check the care label of the fabric and test any cleaning solution on a small, hidden area first. **
