I live near Los Angeles, Calif. It rained for many days non-stop, here.
Today I discovered many of the normally white wood ceiling and side
panels have black dirty spots in our outdoor screened Lani room. 1/2
of a wooden panel is black with this stuff.
My first guess is this is a mold. When I wipe the dirty spot with water
on cloth. Cloth turned dark like plain old dust.
Wiped another dirty panel with bleach water.
Samething, dirt came off making cloth black.
Further, the normally white wood panel has an off-white color in the
areas where I wiped away the black stuff. Could these panels be be damp
Is this mold or something else?
How should I clean these panels? Should I wash each with a bleach water
Thanks for any suggestions.
