Hello, my name is Javier Velez Romero and today I finished my Master Green Cleaning Recertification. This is twice.

The IJCSA courses are very broadspanned and clearly understandable. Besides the definitions for keywords I'm the industry, I also learned alot of basic mixtures featuring key ingredients for recipes to clean floors, carpets, walls, bathrooms and kitchens and also clothes.

It was a very satisfying experience.All the concepts are fully graspable,easy to understand and explained in an easy and unique form.Now I am Master Green Cleaning Recertified.
