To clean and shine a glass table, Valmour proposes 2 solutions:

1 -  The Crystal Windows spray permits cleaning, grease-removing and shining without leaving any marks. Environment-friendly product made with beetroot alcohol

2 - The Meudon Whiting LOUIS XIII is a very fine-grained natural chalk which allows to clean and add  shine to glass surfaces. Dilute 1 volume of Meudon Whiting LOUIS XIII in 3 volumes of water. Spread on the glass. Let dry. Wipe with a Cotton Cloth.
