So I live in a first floor flat, trying to train ds to wipe his feet every time we come in, but my carpeted stairs are constantly filthy! It's a beigey coloured carpet and I do try to stay on top of it but omg it's just vile all the time. What's the best thing I can clean it with, or do I bite the bullet and rip the carpet up completely? Feel like I'm fighting a losing battle. There's only space to open and close front door in the downstairs 'hallway' so taking shoes off down there (with a 4yo, his lunchbox, nursery bag, my handbag, random shopping etc in hand) is not really feasible. Help!!!!
