water heater cleaning?

[viper]

I have always just flushed out the water heater with water pressure to get the calcium particles(white flakes) out. Does anyone use any chemicals in the tank to help dissolve the calcium particles? I know there are chemicals like CLR which can help dissolve calcium build up in shower heads etc. Would it be safe to use anything similar to CLR- like white vinegar or similar products to help dissolve this stuff? Thanks for your suggestions.

Hi viper,
The short answer is no. I just flush the water heater with the small tool one can purchase. Water pressure and the tool do a fine job.

White Vinegar is your answer. It will disolve the calcium in no time. Remember to siphon as much water as you can from the heater. Atwoods usually have up to two gallons of water remaining in the tank after the drain plug is pulled. Once the water is out, introduce enough vinegar until it runs from the drain hole. It may take up to two gallons to do the job. Don't be afraid to let it set overnight, then flush the tank completely
