Guardsman Water Ring Remover Cloth 5 "It works!" 02 June 2020 I am very pleased with this product. Some time ago I realised that I had spilled some water on my table (wooden). When I saw it I instantly got rid of the water - but too late - it had left a dull, light mark. I tried ordinary polish, but no ,it was still there. I ordered the above product and, thankfully the stain has disappeared and you cannot even see where it was!
