There are a couple of options to go about applying the muriatic acid.One way is by adding it directly to the toilet bowl.The method that will be described in detail here is by applying the acid down the overflow of the flush valve assembly.
First,turn off water and proceed to flush it out of the system.Use a plunger or sponge to remove any excessive water left in the bowl and jet hole.Next, take off the tank cover and place a PLASTIC funnel into the overflow tube.Wearing the proper protection,pour no more than a gallon of Muriatic Acid into the funnel at a steady but careful pace.
After finishing the pour,securely place a sandwich bag over the overflow tube and exit the bathroom,closing the door behind you.Once an hour has passed,it should be safe to return and remove the bag. If your toilet has a fill tube connected to the overflow tube, it will be necessary to replace it.
Proceed to turn on the water and flush the toilet a few times until you are confident that all of the Muriatic Acid has been removed from the bowl.If you decide to use a brush during the cleaning process,make sure to choose one that will be not be destroyed by the acid.
