Calgon is a brand of water softener products owned by the Anglo-Dutch concern Reckitt Benckiser.
Advertising
In Portugal, the Calgon advertisement jingle has been the same popular one[1] for almost 30 years.
In Italy, Calgon was called Calfort from 1965 to early 2008.[2]
In the UK & Ireland, Calgon started advertising on TV in March 1985 and it's still in use today.
Criticism
In May 2011, a study by Which? magazine demonstrated that there was no evidence to suggest that washing machines lasted longer when treated with Calgon under "normal" washing conditions. Calgon disputes this, however.[3]
