Why shouldn’t I use CLR to clean the white crud in my hot water tank?

Can you safely drink CLR?

I know its Hot Water.....but it's tied to the plumbing system and if it isn't safe for human consumption I don't want to use it.
I use white vinegar instead......

Hey, if you don't mind if your hair falls out, your teeth turn black and you develope a facial twitch, then go for it. If you then can still see to type let us know how it turned out.

Sorry, maybe it was the wine but I couldn't resist. Truthfully, I have no idea.. Maybe it will work? I just wouldn't try it...

They advertise the stuff as safe for coffee makers so it can't be that bad. Make sure you rinse it thoroughly afterwards because the stuff does stink and will only be worse if you heat it up.

from the Jelmar website: Can I use CLR on my water heater?

No, Jelmar DOES NOT RECOMMEND the use of CLR on a water heater; however, there is a web site that does. Again, JELMAR DOES NOT RECOMMEND THE USE OF CLR IN A WATER HEATER. The reasons Jelmar does not recommend CLR to clean a water heater are: 1) the heat is not compatible with CLR; 2) the water heater cannot be promptly and thoroughly rinsed with cold, clean water; 3) the water heater might have internal metals that are not compatible with CLR.

How are you going to get it into the HW heater? How much are you going to put in?

X2.
I put 1gal of generic white vinegar per 15gal of tank capacity in my fresh water tank. I then open each faucet inside and the outside shower also until I smell vingar and let sit for 4hrs. This concentration mix will go through all your lines/faucets/water heater and dissolve the calcium/crud. Drain them refill with fresh water, run through lines and do a final drain.

Or if just want to treat the water heater tank......drain it, remove relief valve and pour gallon of vinegar in with funnel. Replace relief valve & fill tank then let sit for 4 hrs. Drain and flush. I do this after leaving S/W US due to hard water.

I think next time I'll try your method and do the whole system.
Thanks

Hi All.

We think this is a pretty simple question to answer. And just using "Good Old Fashioned Common Sense, says:

If you "CAN NOT" drink it, then "DO NOT" put it into your Water System, Period.

Best of Luck to you. Good Luck. Happy Travels. Dan & Jill
