How to clean your
indoor plant leaves?

Your houseplants' leaves accumulate dust over weeks — and it's not just an aesthetic issue. A dust-laden leaf absorbs less light, transpires poorly, and is more vulnerable to pests. Regularly cleaning the foliage is one of the simplest and most effective care routines to keep your plants healthy.

The method depends on the size of the leaves, their texture, and their sensitivity to water. This guide explains how to proceed for each type of plant.

Why clean the leaves?

Stomata — the micro-pores through which leaves breathe and transpire — gradually become clogged with dust. As a result, the plant absorbs less light, regulates its temperature less effectively, and becomes more vulnerable to insects and diseases.

Regular cleaning (about once a month) visibly improves the vigor of large-leaved plants like monstera, ficus, or strelitzia. It's also the best time to inspect the undersides of leaves for pests.

"A clean leaf captures light better.
It's the most underestimated care routine."

The 4 methods depending on the plant

🧽

Damp cloth — large, smooth leaves

The most effective method for plants with large, smooth leaves such as monstera, ficus, philodendron, strelitzia, or alocasia. A simple microfiber cloth lightly dampened with room-temperature water is sufficient.

  1. Lightly dampen a microfiber cloth — not soaked, just damp.
  2. Gently support the leaf from underneath with one hand.
  3. Wipe from the base to the tip, in the direction of leaf growth.
  4. Flip the leaf over and clean the underside as well — this is where pests hide.
  5. Let air dry — do not wipe with a dry cloth, as this creates streaks.
🚿

Shower — robust and medium-sized plants

For plants that tolerate water well on their leaves (pothos, dracaena, spider plant, schefflera), a lukewarm shower once a month is the quickest and most thorough method. It cleans all the leaves at once, rinses off pests, and hydrates the foliage.

  1. Place the plant in the shower or sink.
  2. Rinse with lukewarm water (never cold) at low pressure — no powerful direct jet.
  3. Allow the water to drain completely before returning it to its place.
  4. Do not put the plant in direct sunlight immediately — water droplets create a magnifying glass effect that can burn the leaves.

Soft brush — hairy or delicate plants

Some plants have hairy or textured leaves (kalanchoe, gloxinia, some begonias, cacti) that do not tolerate moisture on their surface. A soft-bristled brush — a clean makeup brush works perfectly — can remove dust without water contact.

Gently brush the entire surface of the leaf, sweeping the dust downwards. Always work in dry conditions, in a well-lit area to see the dust.

Revitalizing treatment — dull and lackluster leaves

For leaves that have lost their natural shine — often due to limescale deposits or depleted substrate — a specific revitalizing treatment restores their luster while nourishing them. To be used after basic cleaning, on clean and dry leaves.

This type of treatment is particularly effective on ficus elastica, philodendrons, scheffleras, and all naturally thick and shiny foliage.

Which method for which plant?

Monstera, Alocasia, Strelitzia

🧽 Damp cloth

Large, smooth leaves — wipe leaf by leaf, supporting from underneath.

Ficus elastica, Philodendron

🧽 Cloth + revitalizing treatment

Naturally glossy foliage — revitalizing treatment enhances shine after cleaning.

Pothos, Dracaena, Spider Plant

🚿 Lukewarm shower

Water-tolerant — quickest method for plants with many small leaves.

Calathea, Fern

🧽 Very soft cloth

Fragile leaves — very gentle touch, do not rub. Gentle misting if very dusty.

Cactus & Succulents

🖌️ Dry brush

Never water on spines or fleshy leaves — dry brush only.

Kalanchoe, Begonia

🖌️ Soft brush

Hairy leaves retain moisture — water causes spots and mold.

Orchid

🧽 Slightly damp cloth

Gently wipe the leaf blade. Avoid water in the heart of the plant — guaranteed rot.

Hoya, Golden Pothos

🚿 Shower or cloth

Naturally waxy, resistant leaves — both methods are suitable.

How often should you clean the leaves?

The ideal frequency depends on your home. An apartment in the city with poor ventilation accumulates more dust than a house in the countryside. As a general rule:

✔ Recommended frequency Once a month for large plants with smooth foliage (monstera, ficus, alocasia) — this is enough to keep foliage clean and shiny.

Every 2-3 months for small-leaved or hairy plants — less exposed to visible dust.

With every inspection — take advantage of cleaning to check the undersides of the leaves. This is the best way to detect pests early.

What not to do

❌ Never use these products on your leaves

Diluted milk: leaves sticky residues that attract pests and clog stomata.

Olive oil or pure vegetable oil: same problem — greasy residues, clogged stomata, sticky surface.

Undiluted alcohol: burns leaf cells. If using alcohol (for pests), dilute to 70% and apply only to infested areas.

Cold tap water: limescale spots and thermal shock can mark sensitive leaves. Always use room-temperature water.
