ATF: Bighorn - Stains around AC vent

I have 3 duct vents that have moisture stains around them, 2 are AC output vents and 1 AC return air vent. All are in the back living area surrounding the ceiling fan. There was a TSB 98.01.19 that my dealer said was done. I never had any dripping of any kind or noticeable moisture around the area.
Is there any way to get rid of the stains or lighten them up a little? Also can I get a copy of the TSB and the procedure that was performed on this problem? I want to check my dealers work to make sure it was done.
