There was a post on the Monaco forum I found where a Dynasty owner had his seats cleaned by Fibernew and they came out really nice.
I'm in the same shape, overall the seats are in good condition but need to be cleaned and conditioned. There is a Fibernew rep close to me so that is an option.
Please post what you decide to do and cost.
