Thanks for the tip. My gasket is 16 years old and started leaking last year. After cleaning with a tool that I made to remove toilet paper from the groove, which always worked in the past and several other tricks including olive oil it still would not hold water I took it apart and cleaned it with a scrubbie to get the scale off. The housing where it sits and the slide I had to scrape with a putty knife to get the scale off. It now holds water again but next time I will try the vinegar. Maybe a good Idea to use the vinegar one a year just as a preventive measure.
