And with humidity you get mildew.
I have seen my formerly white walls of the house develop streaks of green, and I was aware that the iron door to bodega was showing signs of mildew.
What I did not know, was that my front door, painted a bright and cheerful red, was being attacked as well.
Nasty stuff, mildew.
To-day, with a few hours respite from the daily rain, I took to the doors with a vengeance. The walls I can do little about at this point, but my doors I can keep mildew free.
Or at least try to.
