Memories Gown Preservation for the past 30 years grew to be one of the largest and most trusted wedding gown preservation companies with the highest quality services in the country. That’s because we dry clean differently than everyone else. We use green dry cleaning solvents, which mean a healthier, long-lasting wedding dress for you to cherish. That’s why our solvents are perc-free to make your gown soft and odor-free. Plus, we filter our cleaning solvents for every garment.
