To maintain the fabric of an old soul sofa, you should follow these steps:

Vacuum the Sofa Regularly: Dust and dirt can accumulate on the fabric of your sofa, making it look dull and worn out. Use a vacuum cleaner with an upholstery attachment to remove any dust, dirt, or debris from the sofa regularly.

Clean Spills and Stains Immediately: If you spill anything on the sofa, clean it up immediately to prevent stains from setting in. Blot the spill with a clean cloth, and avoid rubbing the fabric.

Use a Fabric Protector: Consider using a fabric protector spray to protect the fabric from spills and stains. Follow the instructions on the product carefully.

Rotate Cushions: To prevent the sofa from developing sagging and uneven wear, rotate the cushions regularly.

Avoid Sunlight: Direct sunlight can fade and damage the fabric of your sofa over time. Avoid placing the sofa in direct sunlight, or use curtains or blinds to block out the sun.

Professional Cleaning: Consider having your sofa professionally cleaned every few years to remove deep-set stains and dirt. Make sure to hire a reputable company that specializes in cleaning upholstery.

By following these steps, you can help maintain the fabric of your old soul sofa and ensure that it looks beautiful and comfortable for years to come.
