Thank you for your suggestion. Yes, I am using the measuring spoon but I find that it is still not good enough because when pouring into the washing machine soap container and it tend to drop onto the softener compartment. I prefer the above scoop as it is rectangular shape which fix into the container. I know some soap powder provide the above scoop. If anyone know about it , please let me know which brand so that I can buy it. I saw the above scoop sold at ebay and it is quite expensive.
