How to Clean House Plants

Cleaning house plants is an easy task that often gets overlooked. Just like other surfaces in your home, plant leaves collect dust, dirt, pet hair, and airborne particles. Keeping them clean not only makes your plants look better, but it can also help them make better use of the light they receive.

Pros of Cleaning House Plants?

House plants naturally collect dust on their leaves. Over time, a layer of dust can block some of the light that reaches the leaf surface. Since plants need light for photosynthesis, keeping leaves reasonably clean can help them make the most of the light available to them.

Cleaning also gives you a chance to look closely at your plants. While wiping or rinsing the leaves, you may notice yellowing leaves, damaged areas, pests, or other problems that could otherwise go unnoticed.

You don’t need special plant cleaning products to keep most house plants looking their best. In many cases, plain water and a soft cloth are all you need.

How Often Should You Clean House Plants?

There isn’t one cleaning schedule that works for every plant. Plants in dusty rooms, kitchens, homes with pets, or areas with open windows may need cleaning more often.

A good rule is to check your plants every few weeks. If you can see dust on the leaves, it’s probably time to clean them.

Plants with large, smooth leaves are usually easy to clean. Plants with tiny leaves, fuzzy leaves, delicate foliage, or dense growth require a gentler approach.

Cleaning House Plants with Large, Smooth Leaves

Large leaf plants are some of the easiest house plants to clean.

1. Fill a container with lukewarm water.
2. Dampen a soft, clean microfiber cloth.
3. Gently support the leaf with one hand.
4. Wipe the upper surface of the leaf with the damp cloth.
5. Rinse or clean the cloth as it becomes dirty.
6. Allow the leaves to air dry.

Avoid pressing hard on the leaves. You are trying to remove dust, not scrub the plant.

A microfiber cloth works well because it can pick up dust without requiring a cleaning solution.

Cleaning House Plants That Have Smaller or More Delicate Leaves

Some plants have leaves that are too small, numerous, or delicate to wipe individually. For these plants, gently rinsing the foliage with lukewarm water can be easier.

Place the plant somewhere suitable, such as a sink, bathtub, or shower, and use a gentle stream of water to rinse away dust. Avoid using strong water pressure, which can damage leaves or stems.

Let excess water drain from the pot before returning the plant to its usual location.

If the soil is loose or likely to wash out of the pot, cover the soil temporarily with a cloth or plastic wrap while rinsing and use appropriate drain trap.

What About Cleaning House Plants with Fuzzy or Hairy Leaves?

Plants with fuzzy, velvety, or hairy leaves need special care. Water can become trapped among the tiny hairs and may leave the foliage damaged or discolored.

Instead of wiping these leaves with a wet cloth, use a soft, dry brush to gently remove dust. A clean, soft paintbrush or soft toothbrush can work well for this job.

Always use a very light touch. Delicate leaf hairs can be damaged by rubbing.

Cleaning House Plants with Small Leaves

Plants with lots of small leaves can take forever to clean individually. A gentle rinse is often the easiest option if the plant tolerates getting its foliage wet.

For plants that should not be rinsed, use a soft brush to carefully remove dust. Work slowly rather than trying to clean a large section at once.

Should You Use Leaf Shine Products?

Leaf shine products are not necessary for keeping house plants clean. They can also be unsuitable for some plants.

Avoid using household furniture polish, cooking oils, mayonnaise, milk, or other homemade substances on plant leaves. These products can leave a coating behind and may interfere with the natural surface of the leaf.

Plain water is usually the safest choice for routine dust removal.

Cleaning House Plant Pots

Don’t forget about the pots. Dust and dirt can build up on the outside of plant containers just like they do on other surfaces.

For washable pots, wipe the outside with a damp cloth.

Be careful not to let cleaning products soak into the soil. If you are washing a pot while the plant is still inside it, keep cleaners away from the plant and its soil.

Removing Dead Leaves

Cleaning your house plants is also a good time to remove leaves that are completely dead or badly damaged.

Use clean, sharp scissors or pruning shears when removing plant material, and avoid cutting healthy leaves unnecessarily. If only a small portion of a leaf is damaged, you don’t always need to remove the entire leaf.

Removing dead plant material can make the plant look tidier and gives you an opportunity to check the plant more closely.

Cleaning House Plants Can Help You Spot Pests

As you clean the leaves, look underneath them as well as along the stems. Small insects, webbing, sticky residue, speckled leaves, or other unusual signs can indicate a pest problem.

If you find pests, don’t simply spread them to other plants by using the same cloth or brush. Clean your tools between plants and consider separating an affected plant from your other house plants while you determine the appropriate treatment.

What to Avoid When Cleaning House Plants

When cleaning house plants, more cleaning isn’t necessarily better. Avoid:

• Using household cleaners or disinfectants on plant leaves unless the product is specifically labeled for that use.
• Scrubbing leaves aggressively.
• Using rough sponges or abrasive materials.
• Applying oils or other products simply to make leaves look shiny.
• Using very hot or very cold water.
• Blasting delicate plants with strong water pressure.
• Leaving plants sitting in water after rinsing.
• Ignoring the specific needs of plants with fuzzy, delicate, or sensitive foliage.

Different plants have different care requirements, so when in doubt, check the care instructions for the particular plant.

Don’t Forget the Area Around Your Plants

House plants can collect dust, but the area around them can collect plenty of it too. While cleaning your plants, wipe nearby shelves, tables, windowsills, and plant stands.

You may also find leaves, bits of potting soil, or dead plant material underneath the container. A quick vacuum or wipe-down can finish the job.

Should You Clean House Plants with Milk?

I remember years ago I heard you can use milk for cleaning house plants, but was it accurate and can you really use milk to clean and shine house plant leaves? This is an old-fashioned plant care tip that many people remember from their parents or grandparents. So, is there any truth to it?

Milk can make leaves look shiny, but it isn’t the best choice for routine cleaning. Milk contains proteins, fats, sugars, and minerals that can remain on the leaf after the water evaporates. That leftover film can attract dust and could create an environment where microorganisms can grow. It can also leave the leaves looking dull again as residue builds up.

There is also some confusion because milk has been studied for other uses in gardening, including diluted milk sprays for powdery mildew on certain plants. That doesn’t mean milk is a good substitute for cleaning dusty house plant leaves. These are two very different uses.

For everyday cleaning, plain lukewarm water and a soft, clean cloth are a better choice. They remove dust without leaving a food-based residue behind.

So if you remember wiping your house plants with milk years ago, you weren’t imagining it. It was a real and widely repeated gardening tip. It just isn’t necessary when simple water will do the job just as well.

A Simple Plant Cleaning Routine

Cleaning house plants doesn’t have to become a big project. Every few weeks, take a few minutes to look over your plants and remove visible dust.

Use a damp microfiber cloth for sturdy, smooth leaves, a soft brush for delicate or fuzzy foliage, and a gentle rinse when appropriate. While you’re cleaning, check for pests and damaged leaves, and give the area around the plant a quick cleaning too.

A little regular attention can keep your house plants looking fresh while giving you an opportunity to catch potential problems early. Clean leaves, a clean pot, and a clean spot around the plant can make a noticeable difference in the appearance of your home.
