I agree. I have twin wall polycarbonate also but I use Physan or Green
Shield to keep down the monthly mess. Yes, it's more expensive than bleach,
but smells a lot less. I'm not positive, but I think it also has less
detrimental effects on the plants. Physan spray can damage bloom sprays
sometimes, but I aven't had it effect any plants adversely including small
seedlings. Nothing beats a full scrubdown with a disinfectant. You're going
to get plastered with the stuff and I find Physan less irritating than
bleach. To each his own.

I have a twinwall polycarbonate cover on my GH, and even though I use a 1%
bleach spray monthly, I find it helpful; to pull out the big guns every
now
and then - a pressure washer.

Any advice on cleaning the inside of a greenhouse - top, sides and
all?




There AINT no easy way.
I scrub mine down (14x28), twice a year, slap and dash in the spring,
and
complete in the fall, by hand, using about 10% bleach and some type of
detergent.
I try and keep it free of algae throughout the year by spraying the
glass,
benches and walks every week with one % bleach. AND, good housekeeping
all
year
long.
I have tried a power washer, but as I have a Lexan liner, it just does
not
work.
