Hi, it may seem like a silly question, well I feel silly asking, but my OH has said you have to leave the carpet for a few weeks before hoovering or you will ruin it? I am like, get out of here, but he is adamant, happened to an aunt of his, so its murphys law in his book, this is a load of codswollop, isn't it, I can hoover this weekend if I want, only went in this week?
