Mix the "Tergitol" and "Nacconol" and stir until the "Nacconol" is dissolved and a clear gel is obtained. Then stir in the "Carbitol" or isopropanol and then the water. Finally add the pyrophosphate and stir until a clear solution is obtained. The tetrasodium pyrophosphate content may be increased if desired. The solution may be diluted with 1 or 2 volumes of water and still be an effective cleaner for painted walls and woodwork.
