Lime stone floor tiles have large stain after a red wine glass was dropped in a Xmas party in the lobby of the duilding.
“I wanted to send you this email and congratulate you on a professional job at our offices. I have to say I was extremely impressed with the technique / professionalism that you showed and also with the outcome of the cleaning. I thought that this wine stain would never come out but you have proven me wrong. I would like to pass on your details to all my tenants in our building as a recommendation re your work.”
