Hello, I have had my flooring for 9 years. Each year in the winter it gets harder and harder to clean due to the immense amount of salt that is tracked in. I own a music studio, and have 250 students a week trekking in salt from the parking lot etc. (Those 250 students plus they have parents and siblings that tag along. When you figure 500 + people a week for 9 years, the floor has been incredible. Not worn etc. a few corners have popped up and broken, but the flooring is invincible. MY QUESTION Is...….what would you suggest I use to cut the salt. I mop, scrub, etc, daily, and recently bought an electric scrubber and polisher. Every cleaner/vinyl floor cleaner brings no results.
