I don't think you'll have any problems. My normal procedure for cleaning glass and/or better bottles is a hot soak in Oxyclean Free, usually overnight followed by several warm rinses, let dry and cap until needed. If I find that the Oxyclean just doesn't get the job done, I'll do a hot soak in PBW and that almost always works. Either way, I almost always have spots and/or some leftover film from our hard water. If you it really bugs you, you could do a final rinse with distilled water, but that may still not get you perfectly clear glass.
