4. Maintenance
Cleaning the Fabric
The Aiho AR40 is upholstered with breathable linen fabric. To maintain its appearance and longevity:
- Spot Cleaning: For minor spills, immediately blot with a clean, dry cloth. Do not rub.
- Gentle Cleaning: For tougher stains, use a mild fabric cleaner diluted with water. Apply to a clean cloth and gently dab the affected area. Test on an inconspicuous area first.
- Vacuuming: Regularly vacuum the fabric with an upholstery attachment to remove dust and debris.
- Avoid Harsh Chemicals: Do not use bleach or abrasive cleaners, as these can damage the fabric.
Frame Care
The steel frame provides robust support. To ensure its durability:
- Wipe the metal parts with a soft, damp cloth as needed.
- Ensure all moving parts operate smoothly. If any resistance is felt, check for obstructions.
- The unit features anti-slip foot pads. Periodically check these pads for wear and tear to maintain floor protection.
