Bought for a floor polish up into a new home (when vacation in ensuring cleanliness?) I did not want chemicals and for that matter something very effective. Well not disappointed at all: it is impeccable! A good rubber brush and elbow grease: wet soil, sprinkle a bit, wait a few hours and whether it rub. Everything is gone, great. Rest just rinse with clear water. The package comes with the URL of a Web site full of tips and applications. The rest is a little research, I'm here :) For a first try washing machine brand new, I was not at hand softener, well if: a third of powder in a glass, 2/3 tap water, stir and pour into the machine in the space provided: I think not buy back much either chemical softener (I already have a soap nuts). Next time I will add a few drops of essential oil to a good finish and because it feels a little bit, I do but did not have any towels soft! Do not swallow and always wear household gloves - it stings when small wound - an old product and therefore effective. I will redeem.
