I just read this tip in my new Real Simple. I tried it. I love it!
Take a cotton ball and soak it in bathroom cleaner (think Kaboom) or bleach.
Set it in the corner of your tubs (where pink mildewy stuff may or may not be growing).
Leave it alone for 30 minutes to and hour.
Throw away cotton ball and wipe away the remains of the icky bathtub growing stuff.
