Hii I'm in abit of a stinky sitcho so one of the bed rooms in my house is heavily soiled in dog urine I have carpet cleaned it twice but it still smells so ive decided to remove the carpet and underlay and give it a good scrub underneath it is hardwood flooring would I need to sand ìt? I watched a few tiktoks so I'm not 100% sure on what I'm doing but i will be getting new carpet installed professionally once the old carpet is removed any advise or tips would be really helpful😊
