Leaving a nice smell after cleaning undoubtable is a nice touch after cleaning, i have used a few products but all I have been disapointed with their performance, normally due to the smell fading quickly or they smell like hospital cleaners.. can anyone comment on ther product NI-712 Room Spray & Odour Eliminator which i have heard about?? if its really as good as they claim etc? and whether the smell is nice?
