[Queso]

Can someone translate this for me? http://gstwins.com/gsboard/index.php?topic=15666.0

What kind of acid is he talking about putting in the tank? And what's this Kreem stuff? I don't quite understand what he's talking about doing to the petcock either... Thanks in advance

Well, at this point I'm guessing hydrochloric acid as he states

...and have a good 2 cup full of baking soda handy as well.  Large dry towel or 2, also have inner tube cut to the shape of the petcock, and I also have a block off plate for the cap with inner tube, so when I bolt the 2 plates in with inner tube it's sealed and pressure tight.  You also need clear tape for the first 1-2 steps.  A well ventilated outside area like back yard, etc...far away from the AC/Heater units...I have nightmares about them sucking in the chlorine and filling my house with it...

But, I'll search Kreem with username seshadri_srinath.

Also, it could be Acetone, as stated at the bottom of the post.
