Today was the first day I used Ecover, and Wow, its so much better then Fairy and really does live up to its expectations. When I was cleaning windows I noticed that round the edges the water/soap was dissappearing quicker, still scrimmed, but less of it. The windows look somewhat cleaner too! The smell when I wet the window even on the applicator, is so so pleasant!! hhmm(I used the lemon and aloe vera) Been told that this stuff leaves no residue unlike Fairy, meaning a cleaner window and stays cleaner for longer so can't wait to go back in a month see what the windows are like lol. Will try this on my car next time I clean it too!
