I just used a mop in a room with vinyl records. Distilled water and gentle steam were used. As a result, there was a white film on the floor. Passed the second time, another film. Passed for the third time, couples not included. A bit better. I used to have a steam mop (different brand) and it never did. I chose this one based on the positive reviews and the price. The machine was easy to assemble and operate, so I hope the film won't be a constant problem. ***Update*** Be careful not to use it
