5. Care and Maintenance

Proper care will help maintain the appearance and longevity of your tiramisubest sleeper sofa.

  • Regular Cleaning: Vacuum the velvet fabric regularly using a soft brush attachment to remove dust and debris.
  • Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Do not rub, as this can spread the stain. For stubborn stains, use a mild fabric cleaner specifically designed for velvet, testing on an inconspicuous area first.
  • Avoid Harsh Chemicals: Do not use harsh detergents, abrasive cleaners, or solvents, as these can damage the fabric.
  • Sunlight Exposure: Avoid prolonged exposure to direct sunlight to prevent fading of the fabric.
  • Pet Care: The velvet fabric is designed to be pet-friendly and easy to clean. Regularly remove pet hair with a lint roller or vacuum.
