Smart Cleaning Supplies for a Clean Greenhouse

Keep your greenhouse bright, healthy, and thriving with the right tools.

Maintaining a greenhouse can be a joy—and a bit of a chore. Between damp soil, plant spills, and changing seasons, grime, mould, and pests can gain a foothold. But with the right cleaning supplies and a simple routine, your greenhouse stays fresh, functional, and a thriving sanctuary for your plants. Let’s explore the supplies you need for every greenhouse cleaning task.

Microfibre Cloths and Sponges

Gently wipe leaves and frames—no scratches, no fuss.

Microfibre cloths are essential for gentle cleaning tasks around your greenhouse. They remove dust from leaf surfaces, wipe down frames, and absorb moisture without scratching glass or clay pots. Sponges are ideal for cleaning tables, trays, and shelving tops, absorbing spills while remaining soft on surfaces.

·         Reusable and machine‑washable

·         Safe on plant foliage and glass

·         Great for quick, daily touch-ups

·         Use damp for better wipes

·         Eco‑friendly compared to paper towels

Soft-Bristled Brush or Hand Broom

Tackle soil spills and plant debris—without damaging seedlings.

You’ll often find stray soil bits, prunings, and leaf litter scattered across the greenhouse floor. A soft‑bristled brush or handheld broom makes quick work of this debris without disturbing seedlings or causing spillover into pots. Choose a brush with flexible bristles to reach into corners and between pots.

·         Gentle on fragile roots

·         Reaches narrow gaps

·         Compact and easy to manoeuvre

·         Safe on gravel, soil, or hard floors

·         Ideal for daily sweep-downs

Non-Toxic Surface Cleaner

Remove algae, sap, or hard water marks without harsh chemicals.

Greenhouse surfaces—like shelving, trays, and frames—can get grimy from water stains, sap residue, or algae. A plant-safe surface cleaner lifts grime without harming plants or stainless steel surfaces. Look for gentle, biodegradable formulas with low odour that rinse easily and won’t linger.

·         Safe around greenery and seedlings

·         Biodegradable and eco-conscious

·         Cuts sap, algae, and mineral build-up

·         Mild scent that won't stress plants

·         Effective with a quick rinse

Glass Cleaner (Vinegar‑Based or Minimal Chemical)

Let light in—clear glass is essential for growth.

Light is critical in a greenhouse, and mineral deposits or dust on panes can block sunlight. Use a gentle window cleaner—such as diluted white vinegar or acrylic-safe solution—to restore shine. Avoid ammonia‑based sprays, which can harm painted frames or nearby plants.

·         Streak-free formula for clear panes

·         Safe for frames and sealant

·         Defines full spectrum light entry

·         Fast‑drying to avoid moisture build-up

·         Affordable and eco-friendly option

Disinfectant Spray (Plant-Safe)

Prevent disease by sanitising pots, tools and benches.

Disease and fungal spores lurk in damp corners. Using a plant-safe disinfectant helps eliminate pathogens from pots, watering cans, and benches. Choose an eco-friendly, non-residue formula (such as hydrogen peroxide or citrus-based disinfectants) and spray tools after each use.

·         Reduces risk of mould and mildew

·         Safe on tools and hard surfaces

·         No residue or harsh chemicals

·         Supports a clean planting environment

·         Spray and rinse or air dry only

Garden Hose or Pressure Sprayer

Rinse out soil trays, benches, and pots with ease.

Once a week (or after active gardening), using a hose or gentle pressure sprayer helps rinse away residual soil, algae, or dirty cleaning solution. A nozzle with adjustable flow means you can do a light rinse on delicate seedlings or a stronger spray on hardy surfaces.

·         Fast removal of grime

·         Adjustable pressure for sensitive applications

·         Ideal for benches and tray flourishes

·         Encourages thorough cleaning

·         Easy to rinse tools or plant pots

Floor Mop (Soft Microfibre or Dust Mop)

Keep greenhouse floors tidy to prevent mould and pests.

Regular damp mopping minimises dust, pollen remnants, and soil tracks inside greenhouse paths. A microfibre mop head lifts up fine particles without soaking the floor. Use minimal water to prevent puddles and quickly dry the area after mopping to maintain airflow.

·         Low moisture retention to avoid damp build-up

·         Clear soil tracks from walkways

·         Safe on composite or concrete greenhouse floors

·         Machine-washable mop heads

·         Helps stop algae or slippery spots

Pot Scrubbing Brush

Scrub pots before reuse—clean starts for every seed.

Pots and trays can hold residues of roots, soil-borne fungi, and mineral build-ups. Before reusing, give them a thorough scrub with a pot cleaning brush and disinfectant. This routine ensures healthier seedlings and stops cross-contamination between crops.

·         Use firm bristles but plant-friendly

·         Clean inside rims and drainage holes

·         Quick soak and rinse process

·         Efficient for plastic and terracotta pots

·         Reduces plant disease spread

Organisers & Caddies for Tools

Keep your cleaning gear handy and organised.

Having tools and cleaning supplies stored nearby keeps your routine effortless. Use portable caddies, wall hooks, or small shelving units to organise cloths, sprays, brushes, and gloves. Clear labelling helps avoid confusion—especially helpful when sharing greenhouse duties.

·         Easy access keeps cleaning habits consistent

·         Avoids misplaced tools in plant beds

·         Keeps supplies dry and shaded

·         Lightweight for daily mobility

·         Minimises clutter in gardening zones

Protective Gloves and Apron

Gardening meets hygiene—keep mess off yourself.

Ever pulled a leaky pot from a tray only to get splashed? Waterproof gloves and a gardening apron help protect skin from sap, soil, or cleaning solutions. They keep hands and clothes clean while enabling safe handling of disinfectants or rinsing tasks.

·         Durable yet comfortable

·         Easy to rinse and hang

·         Shields against plant residue and sprays

·         Enhances safety and hygiene

·         Washable and reusable

Air Circulation Tools (Fans or Vent Openers)

Dry moisture fast—cut down condensation and mould.

Moist, warm environments can encourage mould on benches or soil trays. Using small fans or automatic vent openers encourages airflow, keeping surfaces drier between watering sessions. Better air circulation promotes plant health and keeps the greenhouse fresher.

·         Helps prevent fungal growth

·         Promotes evaporation of moisture

·         Safe airflow for temperature control

·         Enhances ventilation post-cleaning

·         Easy to use or install

Compostable Waste Bags & Bins

Contain plant scraps properly—compost, then compost it.

Greenhouses produce a lot of organic matter—spent plants, trimmed shoots, or old soil. Compostable waste bags make it easy to gather scraps, which you can then compost responsibly. Use sealed bins to prevent pests and keep the space clean between visits.

·         Works at room temperature (no plastic build-up)

·         Breaks down easily in compost piles

·         Keeps benches and floors tidy

·         Avoids mix with non-organic waste

·         Lids stop insects or mould proliferation

Outdoor Cleaning Tools for Exterior Maintenance

Wash glazing and frames—let clean light shine in.

Don’t forget the greenhouse exterior! Regularly clean outside glass, frames, and gutters to allow maximum light penetration and prevent algae growth. A mild hose rinse or glass cleaner applied from the outside keeps sunlight flowing maximally inside.

·         Helps prevent moss and algae growth

·         Retains maximum sunlight entry

·         Keeps frames rust-free and taut

·         Maintains overall building cleanliness

·         Supports visual appeal of your garden

Seasonal Deep-Clean Kits

Spring reset or autumn spruce—seasonal cleans boost seasonal growth.

At the change of each season, plan a deeper clean: move benches, scrub trays, clean the floor thoroughly, and remove dust and grime from greenhouse corners. Seasonal deep cleaning prevents long-term build-up and gives your space a fresh reset.

What to include:

·         Full wipe-down of all surfaces

·         Pot and tray sanitisation

·         Vent and gutter clearing

·         Shelf and frame scrub

·         Tool and equipment inspection
