How to clean a corrugated plexiglas roof?

[flopticalcube]

I need to clean the roof of the chicken coop. Its corrugated plexiglas and has at least a decade's worth of build up from the cedar trees around it on top. The result is about an inch or so of soil with even some small plants growing. A broom does no good on that. Any ideas?

Pressure washer would be what I would do

Great idea! I'll dust it off tomorrow and give it a go. Thanks.

Why clean it? Green roofs are super ecological

The thought had crossed my mind actually. But the weight of the build up is beginning to compromise the structural integrity of the pexiglas, especially since its about 30 years old. Its also getting kinda dark in there.

Update: Clean as a whistle! Pressure wash worked a treat.
