Cleaning Greenhouse Windows

If you use your greenhouse all year round, you will need to do regular window cleaning. You need to clean both sides of the glass as plants need the best of sunlight all the time. By keeping your greenhouse windows clean, you will repel diseases and harmful insects away from your plants.

When Should You Clean?

When you are growing summer crops like tomatoes, you should clean your green house closer to winter when all the crops are done. This will save you time and energy as you won’t have to move so many things or worry about getting soap on your plants. If you grow plants like orchids, you should clean during the mild weather in autumn. It will increase light as winter gets closer. Overall, autumn and spring are the usual and most beneficial times to do your greenhouse window cleaning.

Time to Clean

Choose a time to clean when the greenhouse is pretty empty. Sometimes all that is needed is a simple hosing of the roof.

Pick a gentle breezy day and take off all moss and algae that has grown on the glass. Stay away from tools that are likely to scratch the glass. Once the surface dirt is gone, you can start washing. Protect your plants when using anything other than just water. If you can move them, place the plants in a protected area until cleaning is complete, or cover them if they can’t be moved. Plastic sheets work well. Remember to cover any electrical sockets in and around the greenhouse.

To be safe, use a mixture of dish soap (liquid), mild or organic cleaner that doesn’t need to be rinsed. You can use rags or brushes with firm bristles to wipe or rub away dirt and hiding pests. Use a wet, wrung-out mop to do the inside part of the greenhouse roof.

Open the windows to make it easier to clean and dry both sides. Your windows will air-dry quickly on a slightly breezy day. Clean and oil the hinges as you go. Don’t forget the clean and repair the floor as well as the windows. Wash the floor and pots with an appropriate cleaner. You may not want to use the same cleaner on the windows so read the instructions on the product labels.

You can always get a professional window cleaning company to do the job if you lack experience, time or skill.

What You will Need

When window cleaning your greenhouse, you will need to gather the following:

  • Mop
  • Sponge
  • Squeegee
  • rags and clean cloths
  • Bucket with soapy water
  • Ladder

You may choose to use a hose instead of a bucket. If you don’t have a mop, you can always clean the high parts with a sponge attached to a broom handle or cane. Gentle pressure washers can get grime out from under window panel joints. When you use a ladder, choose firm ground and wear non-slip shoes. If possible have a friend help you. Wear goggles to protect your eyes at all times, and gloves to protect your hands from any broken glass. Replace any broken panes.

Enjoy cleaning your greenhouse at least annually. If you’re unsure or just simply don’t want to do it, the safest, most efficient clean can be done by a professional! Call 877-A-Genie-2U today for a free estimate.
