Oh ok it's the same thing but in a concentrated form.
Hydrochloric acid - Wikipedia, the free encyclopedia

I have to get some gloves.

That tank coating would be great after I get the scale out of the tank.

I believe that Muriatic acid is 2% Hydrochloric. So be careful with the mix. Muriatic acid works great on removing blueing from guns also. The coatings work great.

good luck

Muriatic Acid is simply diluted Hydrochloric Acid. Muriatic is about 31-32% Hydrochloric in water. CAUTION!!! Never add the water to the acid; always add the acid to the water. Stir while you are doing this. Wear eye protection and rubber gloves. Have additional water nearby in case you get some acid on you so you can immediately flush the acid off yourself. (I'm a chemist, which is how I know how to do this.)

Try this method.

Cub Cadet FAQ

Thanks alot TMO
I got a gallon of Mauriac Acid from the hardware store for $5.50

I filled the tank to 1/2 full of water and dumped in 3/4 of the Mauriac Acid into the tank.
Left it sit for 20 minutes and flipped the tank over and let it cook for another 20 minutes.
I dumped the mixture out and it came out Brown.
Stuck the garden hose in it and left it flush for 5 minutes and took a look inside the tank with a flashlight.

It looks like Brand spanking new.

I then mixed a quart of Gas with some old 10/30 oil I had sitting in the back of the shed and coated the inside of the tank.
After coating it I emptied the tank and let it dry and bake in the sun for a few hours.

We're Golden with the tank.No leaks and it's cleaner than a whistle.
Now if I haden't dropped the sediment bowl on the stone step going into the shed and busting it :wallbanging::wallbanging:,I could fill it with gas.
