Thank You.... now could you tell me the best method to remove black
mold
from the headliner in a cabin?


There are several varieties of mold that leave blackish marks. I've had
good luck using Clorox spray with bleach, BUT protect any other areas
as the bleach can leave light marks. If your headliner is fabric and
white you can try the same approach. Colored (tan) headliners are often
stained for good. Always spot test of course.
