Normal Cleaning
• Vacuum your chair as needed.
• Do not brush fabric or use a vacuum attachment with a rotary brush. Brushing may permanently damage the nap or change the character of the fabric.
Spot Cleaning
• Immediately soak up the stain with a soft absorbent cloth.
• Do not dry the stain completely or it may set.
• The longer a stain is allowed to remain on a fabric, the more
difficult it is to remove.
Additional Cleaning
• Use a solution of lukewarm water and mild detergent.
• Gently apply in a circular motion, then rinse with warm water and dry with a soft cloth.
