Guardsman Water Ring Remover Cloth 5 "Miracle" Ms Podolska 08 December 2020 It really works! I had four small white water marks on my oak table. I have tried all possible diy methods, nothing worked. I have ordered Guardsman Water Ring Remover Cloth from Lakeland, I rubbed the water marks with the cloth for about 5 minutes. At first nothing was happening and than suddenly all the water marks have disappeared! Thank you Guardsman.
