Laqcuer 29 Oct 2010 12:49 EDT

I looked at a job today that was a  slate lobby with a laqucer on it. It was just done 2 months ago the same as it is every year except now it is all very light and breaking down in some areas. There are 2 runners that look fine underneath and we called the guy that cleans to see what he uses and all he could say was clorox and some green bottled detergent. Can bleach and a cleaner break down laqcuer?
