That is an awesome deal. If that thermoset is the same as Weber, then just try bleach with a green scrubby or steel wool. Then a coating of a good vinyl protectant. If that doesn't bring it back, you can sand it and then coat it with the vinyl protectant. .... But I am assuming it is the same/similar to the Weber Thermoset.
