I have a old bathtub that never seems to get really clean. I always
use a standard cleanser such as Comet or Ajax. Recently I was advised
to try Bar Keepers Friend. Instead of using an abrasive as it's
primary ingredient it uses a mild acid. Not strong enough to burn you
but seems to clean better.

I've only allowed Bon-ami "polishing" cleanser or Barkeepers Friend to
be in my house to avoid this problem.



Now at least I'm glad that neither my wife or I are fanatics about
cleaning or by now the tub would have been totally worn out.
