When you come across a new cleaning problem that you haven't encountered before, it's always best to start with the LEAST aggressive method for handling it and move into the more aggressive method if needed.This includes chemical,cleaning pads, etc.
Obviously that is so you don't ruin or damage anything in the process of cleaning it.Also, check with cleaning reps about chemical interaction so as to make sure you don't create a volatile situation.
Or just do what I do - ASK SOMEONE! Your janitorial supply houses have probably run into a similar situation and can help you solve your problem a lot quicker and with a lot less headache.
Hope this helps!
