Hi, I am ready to give up! My tile floor keeps getting a cloudy film on it even when water alone is applied.You could almost write your nameon it from the film. I have asked professional tile people they advised me to use ammonia and water, vinaegar, grease removers, I have done them all and no luck. Please give me any advice you can. Do you think having some one seal it would be my last hope? Thank You so much!
