Some time ago I had an orange miracle cleaner for the first time (and never again) bought from a TV shop, which does nothing as good as no. It smells a little - not even longer lasting - that's it. Now I have googled to concentrate and was find him here. This orange cleaner works perfectly and I noticed the wonderful smell when I came from outside back into the apartment. So he keeps, as opposed to the other, well. I use it with a spray bottle as a diluent; you have to be a little careful because he is very strong - so try, how much you take. From me a clear recommendation!
