At least once a year, take all your plants out of your greenhouse and
thoroughly clean the greenhouse, benches, shelves and walkways. Spray
with a hose to remove surface dirt and debris. Then apply a disinfectant
(Physan 20). (For TwinWall, rinse with hose and then wash with
a mild liquid dishwashing soap and lukewarm water. Use a soft cloth or
sponge. Rub lightly only in the same direction as channels to avoid scratches.)

Clean glass admits more light and heat. For stubborn spots of algae, spray
