Cleaning is so thoroughly, as described in the Produnktinfo. Here there are actually nothing to complain about. But the smell is unbearable for me. I have tried several times, but the effect of the included perfume is downright daunting for me. A bottle I palmed my husband to allow the visor of his To clean motorcycle helmet, but the remaining two bottles I'll probably or not consume themselves - or discard - must. I will buy this product Dettol not again and can it not also a friend.
