Nigerian Cleaning Solution

I investigate a Nigerian Cleaning solution, mysteriously called STPP.

Ingredients and Analysis

  • NaOH or caustic soda
  • Na2CO3 or soda ash
  • XAl(SO4)2·12 H2O where X is a monovalent cation such as potassium or ammonium. It is referred to as Alum.
  • Al2(SO4)3 or aluminium sulphate
  • CaO or Lime, composed of calcium oxides and hydroxides, usually calcium oxide and/or calcium hydroxide
  • Ca(ClO)2 or calcium hypochlorite in the form of chlorine tablets
  • HCl or Hydrochloric acid


  1. Caustic soda (sodium hydroxide) and soda ash (sodium carbonate) may react with hydrochloric acid to produce water and salt. For example: NaOH + HCl → H2O + NaCl
  2. Lime (calcium hydroxide) and hydrochloric acid may undergo a neutralization reaction, forming water and a calcium chloride salt. For example: Ca(OH)2 + 2HCl → 2H2O + CaCl2
  3. Alum (aluminum sulfate) does not typically react with the other chemicals in the mixture. However, alum is commonly used as a coagulant in water treatment processes to help remove suspended particles and impurities.
  4. Chlorine is often added to water as a disinfectant to kill bacteria, viruses, and other microorganisms.


I am not sure if the cleaning solution will be effective compared to other solutions. Efficacy will have to be validated.
