Keeping your indoor plants clean isn’t just about aesthetics; it’s essential for their health. Dust and dirt that accumulate on a plant’s leaves can block sunlight, inhibiting photosynthesis and affecting the plant’s growth. Incorporating a regular plant care routine, which includes cleaning, is crucial for maintaining plant health.
In this guide, we’ll run through how to clean indoor plant leaves step-by-step, ensuring your plants not only look vibrant but also thrive. Whether you’re dealing with large, glossy leaves or delicate, fuzzy ones, we’ve got you covered with expert tips to maintain a cleaner, healthier plant.
What are the best methods?
Dusting with a Soft Cloth or Brush
Our first suggestion would be to use a microfibre cloth or a soft brush to gently wipe the leaves of leafy plants, such as maidenhair fern and Kentia palm. This will remove any dust that has accumulated on the plant leaves and will allow the plant to photosynthesise more efficiently.
Minimise Dust with an Air Filter
A great way to reduce dust buildup on your plants, is to consider an air filter. Our recommended option, the Briiv natural air filter, offers an eco-friendly way to reduce dust and improve air quality in your home. Using a combination of natural materials like moss, coconut fibres, and activated carbon, Briiv captures airborne dust particles and pollutants, filtering them out of the air.
*Extra tip*
For plants with fuzzy leaves, like African violets, use a soft brush or a makeup brush to avoid damaging the surface.
Rinsing with Lukewarm Water
For plants with larger, smooth leaves, we’d recommend gently rinsing the plant’s leaves in lukewarm water in a shower or sink. Make sure to use light water pressure to avoid damaging the plant. If possible, let the plant drain and dry afterward in a shaded area afterwards.
Using a Spray Bottle
A fine mist of water can often help remove light dust buildup. Again, ensure the plant is in a well-ventilated area to dry off after spraying.
Dabbing with a Damp Sponge
For delicate leaves, such as sticky or fuzzy leaves, lightly dab a damp sponge or cloth to clean off dust and small debris. Make sure not to over-wet the leaves, as this can cause fungal growth, water stains and other issues.

Supporting Plant Structure
For plants like ferns or palms, you can support the leaves with one hand while cleaning with the other to prevent bending or breaking.
Specialised Cleaning Techniques
Some plants require a different approach when it comes to cleaning, and using the right technique ensures that your plant remains healthy and undamaged. Using the right cleaning techniques is essential to keep plants healthy. Here are a few specialised methods you can use to clean your indoor plants effectively:
Lemon Juice and Water for Stubborn Debris
If your plant babies’ leaves are covered in stubborn grime or sticky residue, a natural solution of lemon juice and water can be very effective. Mix a few drops of lemon juice in water and gently wipe down the leaves with a soft cloth. The mild acidity of the lemon helps break down dirt and removes mineral deposits from water stains, while the water rinses it away without harming the plant. Make sure to use the lemon juice sparingly, as too much can damage the plant’s leaves.
Feather Duster for Hard-to-Reach Spots
For large or tall plants where it’s hard to clean each leaf individually, a feather duster can be an excellent tool. The soft feathers can easily remove dust and debris from difficult-to-reach spots without damaging the plant. This method works well for plants with many small or crowded leaves, such as ferns, where manually wiping each leaf would be too time-consuming.
Soft Cloth for Delicate Leaves
Some plants, like African violets or ferns, have particularly delicate leaves that can easily be damaged if handled too roughly. For these plants, use a very soft, damp cloth to gently wipe down each leaf, supporting it from underneath to avoid tearing or bruising.
Swishing Motion for Plants with Leafy Foliage
For plants with dense, leafy foliage, such as spider plants or peace lilies, a gentle swishing motion in lukewarm water can help remove dust while preserving the plant’s structure. Submerge the leaves in water and gently swish them around to loosen dirt and dust. Be careful not to submerge the roots, and let the plant drain thoroughly afterward.
What To Avoid When Cleaning Houseplants
Household Cleaning Products
Avoid using household cleaners like window sprays or furniture polish on plants. These products contain harsh chemicals that can damage the leaf surface, block pores, and disrupt essential processes like respiration and photosynthesis. Stick to gentle solutions like water or a microfibre cloth.
Oils and Leaf Shines
Although leaf shines or oils can make your plants look glossy, they actually block light absorption, hindering photosynthesis. They also attract dust, which means your plants will get dirty faster. It’s best to avoid these products and clean leaves with water instead.
Cold or Hot Water
Extremes in water temperature can shock your plant, leading to stress or damage. Cold water can cause leaf drooping, while hot water can scald the leaves. Always use lukewarm water to keep your plant comfortable and safe.
Abrasive Cloths or Brushes
Rough cloths or sponges can scratch or tear leaves, making them vulnerable to pests or diseases. Use soft cloths or gentle brushes to clean leaves without causing damage.
How often should you clean your indoor plants?
The frequency of cleaning your indoor plants depends on several factors, including the plant type, the environment, and how much dust or debris accumulates. Our general guidelines to follow have been outlined below:
Every 1 to 2 Weeks
For most plants, cleaning their leaves every one to two weeks is ideal. Dust can build up quickly, especially in high-traffic areas, and regular cleaning will prevent it from affecting the plant’s ability to photosynthesise.
High Dust Areas (Every Week)
If your plant is located in an area prone to dust, such as near windows, heating vents, or in rooms with heavy foot traffic, you may want to clean it weekly. This prevents excess dust buildup that could block sunlight or clog the plant’s pores.
Low Dust Areas (Every 2 to 4 Weeks)
Plants in low-dust environments can be cleaned less frequently, such as every two to four weeks. If you notice a light layer of dust starting to accumulate on the leaves, it’s a good sign that it’s time for cleaning.
Post-Pest Treatment
If your plant has experienced a pest infestation, cleaning the leaves after treatment can help remove any lingering pests, eggs, or residues from sprays, ensuring the plant recovers properly.
Seasonal Changes
During seasons with open windows, like spring and summer, plants might collect more dust and need more frequent cleaning. In winter, if the air is dry or your heating system generates dust, you may also need to clean them more often.
Regular cleaning ensures your plants can continue to grow strong and stay healthy, keeping your indoor garden looking its best year-round.
Understanding the Importance of Cleaning Indoor Plant Leaves
The Impact of Dust on Photosynthesis
Photosynthesis is how plants produce energy, converting sunlight into the food they need to grow and thrive. When dust and debris cover the leaves, it blocks light absorption, slowing down this vital process. Without enough energy, plants can become weakened, show signs of stunted growth, and develop yellowing or dull leaves. Cleaning the leaves ensures that they can capture as much light as possible, promoting strong, healthy growth.
Promoting Overall Plant Health
Regularly cleaning the leaves also helps the plant breathe more easily. Plants release oxygen and take in carbon dioxide through small openings in their leaves called stomata. If these pores become clogged with dust, it can disrupt the plant’s ability to exchange gases, which is vital for its metabolic processes. Clean leaves allow your plants to “breathe” properly, contributing to their overall well-being.
A Clean Environment for Pest Prevention
Dust and grime can also attract pests like spider mites and aphids. Dirty leaves provide a hiding spot for these unwanted guests, which can lead to infestations. By keeping your houseplant leaves clean, you reduce the chances of pests settling in and give yourself the opportunity to spot any issues early.
Creating a Green, Low-Maintenance Indoor Environment
Regularly cleaning your indoor plants not only keeps them healthy but also enhances the air quality in your home. For those looking to create a lush indoor space with minimal upkeep, consider a living wall solution like the PlantBox Living Walls Indoor Jungle Plant Bundle. This modular system allows you to incorporate a beautiful and diverse selection of plants in a compact space, providing natural air-purifying benefits while making it easy to manage plant care, especially in homes where space is limited.
