Vartest In The News

Vartest Laboratories, Inc. recently appeared on ABC’s 20/20 in a special titled “20/20 True Confessions: Dirty Little Secrets from the Dry Cleaners”. In the segment, 20/20 sampled 10 drycleaners in Manhattan with identical garments containing mustard, wine, and nail polish stains. Vartest Laboratories was chosen to perform a Spectrophotometric Analysis of the stains on the returned garments to discover just how many of the selected drycleaners were able to remove the stains the best.

The ABC special as well as the results of the investigation can be found here: 20/20 True Confessions
