Cleaning Tank Sensors (level gauges) "overnight"
1-Fill tank to about full - preferably with warm (not hot) water
2-Shake well, add 8oz Caravan Sensor Cleaner through toilet
3-A short drive is helpful but not necessary
4-Fill tank to full with water, preferably warm
5-Allow 8-12 hrs before dumping (or longer, microbes need time to consume and dissolve tank contents)
6-Drain tank. Contents should be mostly broken down to liquid and gauges should read "Empty"
7-If unsuccessful then repeat steps 1-6, increasing dosage to 24-36oz and time to 24-72 hrs
8-Gauges should be restored to working condition
9-If second treatment is not successful (about 1% of users will experience this) contact us and often we can assist with tips that may help you achieve your desired results or Hassle-Free refund.
