John cant see pic very well, but if its polyester then hwe if it dirty.
If its not to bad them m/s , aggitate and wipe clean with micro fibre/towels.
All faux suedes/leatherette/buffalo are synthetic fibre mixes with high polyester to make them soft and give it that sheen/nap look. They are all striaght forward to clean. Look out for any delamination.
