Familiarity: I've used it several times
You wouldn't detail your Bronco with a fine tooth comb then not put a fresh coat of wax on it. Treat your Gore-Tex with the same love and care. Use the Tech Wash in the machine, spritz then on after, while the item is still wet/damp. Then, getting some face shots and repeat as necessary.
