About Us

For over 50 years, our company has created and manufactured “professional grade” stain removal products for large and small hospitals, medical and surgical centers, laboratories, restaurants, wineries, dry cleaners, doctors’ offices, car washes, sports teams and more, worldwide.


The company began in 1953 as Cambridge Diagnostic Products, Inc., started by the father of Roy and Gary Gold, Co-CEOs. Their scientists developed the original stain removal formula in 1963.  Since that time three major improvements have been made.  The first improvement was to incorporate a readily biodegradable surfactant, the second was to remove all added dyes and finally the fragrance was removed as well.  Over time doctors, nurses and lab technicians would “take home” the laboratory brand Erado-Sol® and Cambridge Diagnostic Products decided to offer the home use product Stain Rx®.  Today Stain Rx® is available to the public, on this site and in select retailers.
