depends if you are using any detergents some say cold some say hot and some say in the pot nine days old if I was you I would use hot then cold and then hot and cold because then it would expand and contract and hopefully loosen up all the debris and if its a water heater core I would use white vinegar.

How to Keep Your Water Heater Clean?
By Andreina Urdaneta A clean water heater will heat and maintain water better and last longer. Once a year, flush your water heater, and in extreme hard water areas, at least twice a year. If you feel up to the challenge, here are some tips to help you in a basic cleaning. 1 Turn the water heater and the cold water supply to the water heater off. 2 Hook a high-quality garden hose to the drain valve, and place the other end in an area where hot water will not cause damage. 5. Open the drain valve. 6. Disconnect the cold water pipe on the top of the water heater. This step will let air into the water heater so it will drain. When the water heater is empty, close the drain. 8. Pour tile cleaner into the cold water, leave for a couple of hours and drain the detergent out of the tank. 10. Reconnect the cold water supply to the water heater. Open the cold water valve and let the water heater flush for a couple minutes. 12. Close the drain valve and open the hot water faucet nearest to the tank, and let the water heater fill. 13. When water starts to come out of that faucet, reopen the drain and let the water heater continue to rinse. After all the air is out of the water heater, turn it back on. Take care of your water heater, and it will take care of you. If you keep ignoring the task, your water heater may just leave you in the cold.

Do you use the water heater when you use just cold water?
If water is only drawn from the cold faucet, then no, the water heater is not involved. However, if water is drawn from the hot faucet- even for a few seconds- hot water IS withdrawn from the heater, and fresh cold water drawn in to be heated- even if the hot water did not make it all the way through the pipe to the faucet- and the water heater will work to heat that fresh cold water.
