Before I cleaned my window to walk with the cream and then scoured with the product very effective glass but not suitable and I discovered this when I test ... Unconvincing result the product flows not even three minutes while no means to leave the problem to 5min as shown in addition you have to stay next to wipe is flowing, it smells very bad but then it is even unbearable at the time of spraying more and the result is quite mixed it must still rubbed and rinsed and it is not really very effective .... In the final I was a little disappointed for the price and I went back to my old method more Economic and fast for a more convincing result
