Scale cleaner combines with underwater metal 
ion to form soluble complex salts and 
prevents scale through precipitation of carbonates, 
sulfates and silicates. 
Also, it reacts slowly on the surface where scale
 formation is already done to change 
it to soluble material. 
This will maintain the cleanliness of the pipe wall.
  The sludge is easily removed since it 
turns into little particle in the inside of the boiler.
