“Washing machines live longer with Calgon!”
Actually they don’t!
Have you seen that advert? Warning you about how your washing machine gets damaged by limescale if you live in a hard water area!
Well what Calgon don’t tell you is that all major washing powder and most generic store brands come with a water softner and as long as you use the correct amount of powder (too much is fine but not too little) you’ll never have a problem!
