Guardsman Water Ring Remover Cloth 5 "Amazing" Lynne 06 September 2017 I had white marks on two different pieces of solid oak furniture caused by wiping off spills. Tried everything and had resorted to covering the marks up with ornaments which was really annoying! Bought this but really didn't expect it to work. It was amazing. A quick wipe and the marks just vanished. Does leave a slight sheen but I just gave the whole top a quick once over to even it out. Really impressed.
