RV water heater internal scale

Is there a way to remove the scale on the inside of my 2005 class a water heater? Draining doesn't seem to do it.
Thanks,
  • This was discussed a while back. Here is the link

    I drained my hot water tank every year, but this spring I used the vinegar procedure to rid the heater of lime scale that was breaking off and clogging the faucets. We just returned from a 2 1/2 month 8,500 mile summer trip and had no trouble with lime. The vinegar procedure WORKS!
  • I use one of these at least once a year to flush my tank. You can turn it to spray in all directions and really get the crud out of the bottom of the tank.
