So I just used a new Tub and Tile cleaner in our bathroom that has marble tile and found that it left discolored/stained areas on the floor. Turns out that despite no warning on the bottle itself, the website for the brand says not to use it on marble because of the acid it contains. Here's the ingredient list. I assume the lactic acid is what caused the discoloration.

Water; Lactic Acid; Decyl Glucoside; Lauramine Oxide; [Fragrance: Citrus Limon (Lemon) Peel Oil; Abies Alba (Fir) Leaf Oil; benzyl benzoate; geraniol; dipropylene glycol; citrus aurantium dulcis (orange) peel oil; methyl ionones; 4-tert-butylcyclohexyl acetate; linalyl acetate; terpenesandterpenoids,lemon-oil; citrus limon (lemon) peel oil; benzyl acetate; limonene]; Lauryl Glucoside

What are my options for repairing this?
