Guardsman Water Ring Remover Cloth 5 "Amazing!" Mr Beresford 27 July 2019 I bought this cloth as we had a number of water marks on our Ercol dining table and sideboard. I was somewhat sceptical that it mould remove all the marks. However, after 2/3 minutes of rubbing on the worst mark, it has completely gone. I am really amazed. Great product and worth the price anyday!
