      Can you use Muratic Acid to unclog drain pipes? (Household pipes from the kitchen, bathroom)

      If so, how much should be used?

      Since it will not work, don’t bother. And once it is in the drain, if the pipe is completely plugged, a plumber is going to be put in a hazardous situation, not to mention possible damage to his equipment, trying to unplug the drain. If you have to use anything, stay with the commercial drain cleaners. They also do not usually work, but they are at least diluted enough so that the plumber can work through them.

      Muriatic acid (Hyrdrochloric)is good for disolving Calcium deposits in older toilets. Often
      the fushing rim ports will be occluded by these deposits or the siphon jet will build up enough to give poor performance.
      Pour a gallon into the bowl slowly and cover with a piece of plastic to contain the fumes ( a
      large garbage bag will do very nicely), let it stand over night and flush in the morning.
      Read the danger lable on the acid container and heed the instructions.
      If the toilet stoppage is do to organic material, try clearing it with a closet auger. It may be a sewer problem if sewage is found in the bathtub or shower.

      Here you see a classic example of a glorified helper acting like a chemist. I am a chemist, so here’s the scoop:
      HCl (hydrochloric acid) is an aqueous acid, in other words, it is prepared by dissolving Hydrogen chloride in water. Since it is an aqueous acid, it will simply dilute with any water in the line. Therefore, it poses no significant risk to the plumber or the equipment.

      Bud is right that hydrochloric acid is useful for dissolving calcium or magnesium salts that build up with time. However, EDTA (ethyldiaminetetraacetic acid) is better for getting rid of calcium, and is safer, but it takes more time to work.

      The reason why sulfuric acid is used in drains is simple. Sulfuric acid (H2SO4) will turn organic matter to carbon, but will get hot and water will be released, along with some sulfate gases. H2SO4 does put the plumber and equipment at risk, so be sure to tell the plumber that the H2SO4 is in the line, in the event that the acid doesn’t work.
      Good luck
