Hi All: I am back to IL after marriage. I am starting my new life in a new house (not exactly). We had rented a house which quite old and I as a good wife shud keep it neat & tidy without coplaining Bathroom tiles on the wall is very dirty with some stains. Can anyone give me tips to clean them ? Water in this area is really very hard. This stains vessels, sinks and tiles. Any tips to clean them and maintaining will be very helpful. Thanks!!
