    No one has addressed the stains? HOW DO I REMOVE THEM without ruining the ‘glaze’?

    Your not going to know if they are truly stains until you try.
    Pretty much guarantee any cleaning staff have not been allowing dwell time of product they will most likely be slop mopping.
    Sèveral have mentioned peroxide I wouldnt use it straight let the detergent buffer it so its not too acidic

    You don't want to use an acid cleaner. Think of it as a tile and grout job without the tile. Concrete is porous the beverage spills will have soaked into the concrete and will wick. Put an impregnating sealer on it. It takes some pressure to remove the cream but test.
