    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.
