You may be curious why cleaning your greenhouse is so important but you have to remember one thing: the same environment used for producing lush, healthy plants and plants that thrive is the same environment that can harbor pests, insects, and diseases that might destroy the plants you’ve worked so hard to grow. If you have a seasonal greenhouse, you should give it a thorough cleaning at the end of the growing season regardless of how many plants and pots are in there. Year-round greenhouses need several cleanings a year but don’t worry; you’ll get used to it more quickly than you think, so get your cleaners, water, and sponges ready.
We’ve compiled the best products on the market to easily get rid of these pests, while keeping your greenhouse brand new and more importantly making the job super easy for you! So read on to find the best tools for the job.

Greenhouse Cleaning Products: 5 Things to Consider
If you want your greenhouse cleaning to be most effective, it’s best to use products that are as natural as possible and eco-friendly to boot.
1. Greenhouse Disinfectant
If you’re wondering why it’s so important for greenhouses to be disinfected regularly, there’s a simple answer. A clean greenhouse is less likely to harbor pests and diseases, and it is less likely to have tons of pathogens that can be harmful to the plants. Even dust particles that fall from pots can contain either fungi or certain bacteria. A good disinfectant also gets rid of algae and other harmful growths. Algae needs to be eliminated because the more algae you have, the more likely you are to have shore flies and fungus gnats, which wreak havoc in thousands of greenhouses and plants all over the globe every year. Remember, unlike in your home, don’t use bleach as a disinfectant in your greenhouse, even if diluted with water! Your plants will thank you for it later.
In addition to cleaning and disinfecting your windows in the greenhouse, you should go ahead and wash and disinfect work tables, benches, and even your cleaning containers if you reuse them (which most people do). Using disinfectants made for greenhouses is a smart option, of course, but as long as you know that they will be healthy to use, you should be fine.
2. Greenhouse Glass Cleaner
If you’ve ever wondered why cleaning the glass in your greenhouse garden is so important, you’re in the right place. When you’ve chosen glass windows instead of plastic ones, your greenhouse cleaning efforts may take a little longer but it is well worth it in the end. Why is cleaning the glass so important? It’s important for many reasons. First of all, you need a sufficient amount of sunlight and warmth coming into your greenhouse in order for your plants to grow and thrive. The only way to do that is to make sure that the glass is as clean as possible day in and day out, not just during the growing season. A clean greenhouse always means spotlessly clean windows and it’s important to clean them both inside and out.
It’s obvious why the outside of your glass windows get dirty because debris from the elements can be left behind after it rains or is windy, but what about the inside of the glass? Oddly enough, you can still find debris on this part of your glass windows. Things like algae, plant debris, and even debris that results from watering your plants all contribute to dirty windows but keeping them looking as good as new is much easier than you think. A top-notch glass cleaner will make cleaning your greenhouse windows faster and simpler than you think, especially if you find the right cleaning product in the beginning.
3. Telescopic Window Cleaners
Okay, so you’ve decided that your greenhouse windows need a good cleaning but you’re a little nervous about how you’re going to reach the panes at the very top of the greenhouse. What do you do next? After all, this isn’t like cleaning the items inside of the greenhouse or even cleaning the greenhouse floor. Cleaning your greenhouse windows has to be done regularly, at the very least around the end of the growing season if the greenhouse is seasonal; however, if you know just what to do, you can save yourself a lot of time and money from one year to the next.
Fortunately, there are now special products and tools that you can use to make the task a lot easier and one of those tools is a telescopic window cleaner. Made to reach around 10 to 12 feet high on average, these special poles make it super easy to clean your windows without even climbing a ladder, which is great because no one feels completely safe on top of a high ladder. They are sturdy, well made, and, best of all, built to reach the very top of the greenhouse even if you have the tallest one in the neighborhood, allowing you to clean all of your windows in no time. Even better, they usually cost a lot less than you think.
4. Glass Steam Cleaners
One of the best ways to clean mirrors and windows is with steam because not only is steam very efficient at cleaning glass surfaces but it can be effective even without using a chemical-filled solution of any type. When it’s impractical or dangerous to clean algae, pests, or any other type of debris from your windows, a good steam cleaner made just for glass may be just what you need to do the job right. All that’s required is a little water. This technique is nothing new but what is new are some of the advances that allow the steam to allow for proper greenhouse cleaning, whether you’re trying to remove dried leaves, pests, or even debris and disease from nearby plants.
Even dried-on soil and mud is never a problem with steam cleaners, making it super easy the next time you want to wash your windows off thoroughly. Best of all, you don’t necessarily have to include a chemical-filled or bleach solution to get the job done right because most people use steam cleaners with just the water and nothing else. Another advantage of using these cleaners is that the plants inside of your greenhouse pots are much safer because they will never be exposed to anything harmful.
5. Greenhouse Fumigator
Once you learn about plant pathogens, pests and diseases that can ruin your plants, and the harmful effects of algae, you’ll realize how important it is to keep all of your greenhouses spotless and super clean all year long. After all, if you want your garden to last, you have to keep everything inside of your greenhouse clean. Before you harvest, you can give your greenhouse a good thorough cleaning using a fumigator, which will quickly become one of your favorite greenhouse tools.
Much like other products, there are fumigators made just for greenhouses and they do a great job of getting rid of algae, leaves and other items with diseases on them, and even the many plant pathogens that can cause plants to die, including bacteria and fungi. If you are new to growing plants or veggies in your greenhouse garden and you want to give those items a great start each year, a top-notch fumigation will go a long way in preparing your greenhouse garden so that anything you plant there is much more likely to grow and thrive, free of disease or anything else that may hinder its growth.
Best Greenhouse Disinfectants
Below are three very good disinfectants that can make a good overall greenhouse clean a super-easy chore.
Physan 20 Broad-Range Disinfectant
Undoubtedly one of the best disinfectants on the market, Physan 20 is not only a super-efficient disinfecting product but is also environmentally friendly, has been approved by the FDA to use directly on plants, and even comes in a pleasant scent. It is therefore a perfect product for your greenhouse garden. Even better, this product will never discolor your skin like a lot of other disinfectants will, which is a huge perk if you just happen to forget to wear gloves one day. More importantly, since it is concentrated and you’ll only use a small amount of it each time you use it, this eight-ounce bottle of Physan 20 should last you a very long time. In most cases, you’ll only use one tablespoon of the product in a bucket of 20 gallons of water, although some situations may require a different dilution combination. It kills viruses, fungi, algae, and many types of bacteria on all types of plants and it is one of the best disinfectants on the market today for greenhouses of all types.
Hydrofarm Physan PSPH20 Physan 20 Disinfectant Germicide
Made specifically for cleaning and maintaining your greenhouse, it is also a very good product to use on firm outdoor surfaces, plants, and almost everything else in or around your greenhouse. A good greenhouse wash and disinfecting job, whether done a few times a year or just after the growing season, is crucial if you want the greenhouse and everything inside of it to stay healthy, fresh, and thriving all year long. This disinfectant comes in a one-gallon container that is concentrated and therefore should last a very long time. You can also use it for cleaning birdbaths, decorative water fountains, and even fixtures such as swimming pools or spas and hot tubs. It gets rid of fungi, viruses, and bacteria on your plants, pots, and anything else you’ve considered using bleach on until you realized that bleach may be too harsh in the end. It helps prevent disease-spreading organisms from getting to places where they shouldn’t be. As long as you make sure that you follow the directions and come up with the right solution, everything the solution touches is guaranteed to be safe. It even cleans lawn and turf grass, making it the perfect solution for all of your gardening and greenhouse needs.
Agralan M92 Citrox Greenhouse Disinfectant
This disinfectant is so natural and healthy that you don’t even have to remove your plants before disinfecting your greenhouse. It is a 500ml container of concentrated disinfectant so you’ll have to dilute it with water before you use it anywhere in your greenhouse.

Citrox can be used to clean and disinfect not just your greenhouse but also your tools, pots, capillary matting, seed trays, sand beds, and even your bird tables. In other words, it’s good for both greenhouses and gardens as well as numerous accessories and structures in your yard. With Citrox, you can use the diluted solution to wash bulbs, tubers, corms, pond accessories, and so much more. You can more easily keep your water butts sweet and your birdbaths extra clean, and you can do it all cheaply and without worrying about harming the environment. From pots to gardening tools, decorative water fountains, and the greenhouse plants themselves, this disinfectant made out of citrus fruit extracts fights tons of bacterial and fungal diseases, and it never harms either plants or insect predators that are there for biological control. In fact, as long as you use the product according to directions, it is 100% safe to use it on almost everything.

Best Greenhouse Fumigators
Here are some excellent fumigators made just for greenhouses that you are sure to love.
Doktor Doom DDTRF 3-Ounce Total Release Fogger
Specifically made for greenhouses, it promises to get rid of all types of pests so that your fruits, vegetables, and herbs grow their best once they’re planted. The Doktor Doom fogger controls spider mites, aphids, and fungus gnats as well as many other pests so that you can take your growing skill to the next level and produce healthy plants that you’ll love day in and day out.

The main ingredient in the fogger, pyrethrum, will biodegrade within hours of the spraying, which you’ll like because it doesn’t even leave behind any residue or unpleasant smell. You can also use the fogger in storage areas and anywhere else that can become a place where you might find algae, diseases, or anything else that will interfere with the growing process. If you want your greenhouse more than just clean, you need the Doktor Doom Total Release fogger.
BASF Pyrethrum TR Fogger
A clean greenhouse is a more productive greenhouse. When your greenhouse cleaning involves a high-quality fumigation, you’ll know that the greenhouse is as clean as it can be. After all, you need more than just water to fully clean an entire greenhouse, especially when you consider how stubborn dead leaves, all types of pests, algae, and stuck-on soil can be to remove. Plant diseases can ruin every living thing in your greenhouse and since a healthy plant will only stay that way when it remains free of diseases and pathogens that can cause disease, this fogger is a great way to start a new greenhouse or even to refresh an existing one. Just like a new greenhouse, however, an older one can be renovated into one that is like new if you know how to do this. It doesn’t matter which plant material you’re working with or which pests you’re trying to get rid of because a thorough fumigation will make certain that your next greenhouse cleaning job is top-notch and lasts a long time. Indeed, with foggers such as this one, you won’t have to use it very often because the job it does is always meant to last.
DeadFast Greenhouse Smoke Fumigator
When you use the DeadFast fumigator, there’s no need to worry about the type of plant material in the things you’re growing, quaternary ammonium solutions that are so popular, tough algae, pests that might be attached to leaves or pots, bleach or other types of solutions that are cumbersome to mix together, or any type of disease that you frequently hear about when it comes to greenhouses. The fact is that this fumigator gets rid of everything including all types of disease, providing you with a powerful cleaning that is more than just a basic wash. Flying or crawling pests, leaves or soil with disease in them, and visible algae growing on pots, leaves, or even your favorite plant can all be eliminated with the right fumigation and DeadFast can help you get it. Common H20, or water, isn’t enough to thoroughly clean a greenhouse before you start planting things but a fumigation wipes the slate clean, so to speak, and allows you to plant whatever you want in your greenhouse. It is easy to understand why the right greenhouse clean is so important. If you want gorgeous, healthy plants in your greenhouse, you have to give those plants the right start; many times, this means a thorough fumigation.
As you can see, finding the best products to clean your greenhouse isn’t that difficult, especially once you learn what you need and where to get it. Plants of all types need more than just water and the right-sized growing pots to be successful. If you want healthy soil, plants that are free of disease, and plants that will grow healthy and strong, you have to first make sure that your greenhouse is as clean as it can be. This doesn’t mean that the plant material, the amount of cleaner or water you use, the type of pots you purchase, or even the products you buy to keep away disease aren’t important. It’s just that to benefit from all of these things, your greenhouse has to be clean from top to bottom. If it isn’t, none of the other things you do for your plants will make a difference and you’ll end up disappointed in the results.
If you’ve decided to plant fruits or veggies in your greenhouse, to take that decision seriously is smart, and like other structures around your home, you can’t just buy some soap and water and expect your greenhouse to be clean enough to grow nice things. Do your research, make sure you have plenty of water on hand, and get used to learning more about plants and plant diseases so that you can know what to do immediately so that your greenhouse will thrive.
