There are many opinions on the best way to clean a steam boiler. One of the oldest ways is to dissolve a pound of tri-sodium phosphate (TSP) and a pound of caustic soda (lye) in water and pour it into the boiler. Let it cook for a few hours and then drain the boiler. If you can't buy TSP in your town, try a commercial soap called MEX.

Phosphate buffers the boiler water, reducing the chance of large pH changes due to the development of high caustic concentrations. Excess caustic combines with disodium phosphate and forms trisodium phosphate. Sufficient disodium phosphate must be available to combine with all of the free caustic in order to form trisodium phosphate.

A pH/phosphate program in a boiler water system is controlled by: (1) determining the feed rate of the phosphate to the boiler by adding to a phosphate-feed stream containing the phosphate feeding to the boiler a phosphate-feed tracer in known proportion to the phosphate, determining the concentration of the phosphate-feed tracer in the phosphate-feed stream and correlating the phosphate-feed
I work in the commercial/industrial side of plumbing, all new systems I install are flushed with a TriSodium Phosphate (TSP) solution during commissioning of the system, this is to clean any cutting oils or slag that might be present in the system.
New boilers must be washed out thoroughly. The steps required for one method of boiling out are as follows: 1. Dissolve 5 pounds of caustic soda and 1 1/2 pounds of sodium nitrate or 10 pounds of trisodium phosphate for each 1,000 gallons of water the boiler holds at steaming level. Put the mixture into the boiler as a . Figure 1-35.
HOW TO USE TRISODIUM PHOSPHATE: For General Cleaning: Mix 10g of TSP per litre of warm / hot water. Apply using a damp sponge or cloth or mop to surface and allow a few minutes to work. Rinse thoroughly with clean water and dry. For Heavy Duty Cleaning: To remove heavy grease and oil, mix 15g - 20g of TSP per litre of hot water.
