The structure is 15 years old, but the PC covering is 9.

Based upon the ultra clear appearance post-wash, I think there is no issue
with the age of the covering.

Over the weekend, I pressure-washed the interior and exterior of my
greenhouse. I have to admit that I was a bit sloth in my application of
Physan over the winter (it was too damned cold to go out), but I didn't
realize the degree of contamination there, or from pollution and trees on
the outside.

I have been growing my orchids in the dark!

I'm sure I'll see more blooming shortly...

Don't let this happen to you!
