Cleaning holding tank sensor

dhlOASIS

our holding tank level indicator isn't working. I would like to try and clean it first. Has anyone done this and do you have any tips?

Easy job, but not a pleasant one.  Gentle cleaning with a brush and water.  The usual cause is that it gets caked with calcium deposits and/or paper.  Best case, it will last a few more years.  Worst case, you spend $80 for a new one.

You can try rinsing it with toilet bowl cleaner too.

@LaRea and @Black_Diamond. Thanks for the help. Going to give it a try this week.
