Just to let you know---that 'ecos' on the front doesn't really mean anything! I always rinse my bottle and then pour the remainder into the dishwasher when the bottle is empty. Well, the person taking it downstairs to the basement had it turned a little funny and the bottle dripped quite a bit out onto the carpet. This morning, the carpet it bleached almost completely white and even melted a little everywhere there was a drop. I am so upset, and so disappointed in a product that would do that much damage, even diluted! RIDICULOUS! A normal caustic product masquerading around as something better for the environment. I should have known better. so frustrated!
