Greenhouse Cleaning and Maintenance
Cleaning and Maintenance
|By Carol Yaw
With only a few minutes of ongoing maintenance weekly, your plants will
thrive with minimum pests and disease challenges, increased light and
better air circulation!
Once a week take time to remove dead plant material from plants and soil.
Watch for slugs and other pests and disease on plants, in pots, under
trays, in corners and beneath benches and treat as soon as possible. Use
only sterilized soils and containers in your greenhouse for minimum
disease and pest challenges. Sterilize used pots, flats, other containers
and tools with a disinfectant like Physan
20 before reuse. Space your plants out so they arent crowding
each other for increased light and better air circulation.
|At least once a year (I generally
do this in late summer) take all your plants out of the greenhouse and thoroughly
clean the frame, glazing, benches, shelves, flooring and growing accessories.
Spray with a hose to remove general surface dirt and debris inside and out.
|| For stubborn spots of algae, spray Physan
20 or a mild mixture of household bleach and let soak before rinsing.
To clean off tree pitch and adhesive residue I recommend Citrus
Cleaner. Windex Outdoor Concentrated Cleaner (hose end form) makes cleaning
greenhouse glass a breeze.

UV-resistant surface treatment on one side of the polycarbonate sheet significantly
improves long-term weatherability. Periodic cleaning using proper procedures
and compatible cleaners is recommended to prolong the service life.
For general cleaning, it is recommended that the following instructions
and cleaning agents be used. These procedures and cleaners are also recommended
for use on the untreated, interior surface of the polycarbonate sheet, and
for acrylic and APET plastics.
- Rinse sheet with lukewarm water.
- Wash sheet with a mild soap and
- Use a soft cloth or sponge and
gently wash to loosen remaining dirt and grime.
DO NOT SCRUB or use brushes or squeegees.
The coating on polycarbonate sheets is UV-resistant; IT IS NOT A MAR-
- Repeat rinse and dry with a soft
cloth to prevent water spotting.
Cleaning Agents that have been found to be COMPATIBLE
with polycarbonate sheets under laboratory conditions:
VM&P grade Naptha
Windex with Ammonia
Cleaning Agents that have been found to be INCOMPATIBLE with polycarbonate
sheets under laboratory conditions:
IMPORTANT: If a material is found to be incompatible
in a short-term test, it will usually be found to be incompatible in the
field. The converse, however, is not always true. Favorable performance
is no guarantee that actual end-use conditions have been duplicated. Therefore,
these results should be used as a guide only and the products must be
tested under actual end-use conditions by the user.
Polycarbonate sheets are treated on one side. This treated
side must be glazed outward or toward the light source to provide protection
for polycarbonate sheet substrate.
