Before diving into cleaning techniques, let’s clarify exactly what “synthetic rattan” means.
Synthetic rattan (also known as resin wicker or PE rattan) is a man-made version of natural rattan — a tropical vine used traditionally for weaving furniture. Instead of plant fibres, synthetic rattan uses polyethylene (PE) or polypropylene (PP), which are types of durable plastic. These materials are UV-resistant, non-porous, and far more resilient against moisture and mildew than organic rattan.
Weatherproof: Won’t rot, crack, or fade easily under rain and sunshine.
Low maintenance: Needs only occasional cleaning.
Lightweight: Easy to move and rearrange.
Environmentally friendly options: Many PE rattan weaves are 100% recyclable.
Stylish: Mimics the look of natural rattan while offering better durability.
In short, synthetic rattan gives you that relaxed, holiday resort look without the constant upkeep associated with natural materials of your Luxury Rattan Outdoor Furniture UK
Even though synthetic rattan is designed to withstand outdoor conditions, dirt, pollen, bird droppings, and pollution can build up over time.
If left untreated, these contaminants can:
Dull the furniture’s finish
Trap moisture in crevices
Encourage mould or mildew growth
Shorten the lifespan of the furniture
Regular cleaning keeps your furniture looking pristine, prevents wear, and makes it more inviting to use.
By understanding these specific challenges, you can appreciate why a proactive approach to care is so vital. It’s about more than just aesthetics; it’s about safeguarding your investment, ensuring the structural integrity of the material, and ultimately, extending the joy and utility you derive from your outdoor space. Regular cleaning acts as a shield, preventing these common UK-specific issues from taking hold and preserving that sought-after 'Luxury Rattan Outdoor Furniture UK' look and feel.
The frequency of cleaning depends on how often you use the furniture and where it’s stored.
Light use (e.g., balcony furniture): Every 4–6 weeks.
Heavy use (e.g., garden dining sets): Every 2–3 weeks during spring and summer.
End-of-season deep clean: Always do a thorough clean before winter storage.
In the UK, the best times for deep cleaning are usually late spring (after the pollen season) and early autumn (before you pack furniture away for winter).
Here’s the complete process for cleaning your synthetic rattan furniture safely and effectively.
Choose a dry, shaded area outdoors. Direct sunlight can cause cleaning solutions to evaporate too quickly, leaving streaks. Remove all cushions and decorative accessories — we’ll clean those separately later.
Things you’ll need:
Soft brush or vacuum cleaner with brush attachment
Bucket of warm water
Mild washing-up liquid or garden furniture cleaner
Microfibre cloths
Soft sponge or toothbrush (for tight crevices)
Hose or watering can
Dry towel
Optional for deep cleaning:
White vinegar
Baking soda
Soft bristle paintbrush
Grab a soft brush or use the brush nozzle on your vacuum cleaner to remove loose dirt and debris from between the wicker weaves. Twigs, leaves, or mud often get trapped in the gaps, especially if furniture is left outdoors.
Tip: Work methodically from top to bottom to prevent dirt from falling onto cleaned sections.
Mix a small amount of mild washing-up liquid (for example, a few drops of Fairy Liquid) into a bucket of warm water. Dip your soft cloth or sponge into the suds and gently wipe down the rattan.
Avoid harsh detergents, bleach, or abrasive cleaners — they can strip protective coatings and make synthetic fibres brittle.
For areas that need deeper cleaning, use a soft toothbrush or small paintbrush to scrub inside the weave. This reaches the grime that collects in tiny crevices.
Use a garden hose on low pressure, or pour clean water from a watering can, to rinse off soap residue. High-pressure washers are not recommended — they can cause the rattan strands to loosen or split.
Make sure all detergent is rinsed off, as leftover suds can leave streaks or attract more dirt over time.
Wipe furniture with a soft dry towel, then leave it to air dry in a shaded, ventilated area. Avoid direct sun exposure while drying because heat can warp the structure slightly if it’s still damp.
Never store or cover synthetic rattan furniture when wet — trapped moisture can encourage mould to grow around the frame or cushions.

Even with good maintenance, the damp UK climate can sometimes cause mould or mildew to appear — especially on furniture stored in sheds or under covers for long periods.
To treat mild mildew:
Mix 1 part white vinegar with 4 parts warm water.
Dip a soft cloth into the solution and wipe the affected areas.
Rinse thoroughly with clean water and let it air dry.
For stubborn patches, sprinkle a small amount of baking soda over the area after cleaning with vinegar, then lightly brush with a soft toothbrush. This combination gently lifts stains and neutralises odours without harming the surface.
Most synthetic luxury rattan outdoor furniture sets come with removable seat or back cushions. These require different care than the rattan itself.
Check the care label first — many UK outdoor cushions are machine washable.
Use a mild detergent on a cold wash or gentle cycle.
Air dry completely before putting them back on the pads (never tumble dry).
Wipe the fabric with a damp cloth and mild soap.
Spot-treat stains using a fabric-safe upholstery cleaner.
Avoid soaking the cushions to prevent internal foam from staying damp.
If cushions have absorbed rainwater or damp, remove the covers and let the foam dry fully in a well-ventilated space.
When autumn arrives and outdoor entertaining starts to wind down, it’s time for a more thorough deep clean before storage of
Follow the same cleaning steps above but include these extras:
Inspect the furniture for damage — loose weaves, cracked plastic, or rust on frames.
Tighten any loose screws or bolts.
Apply a small amount of car wax or silicone spray to metal parts to prevent corrosion.
Use a non-abrasive furniture polish on the rattan itself for added shine and water resistance.
Allow the furniture to dry completely before covering or moving into storage.
The damp British winter can be tough on outdoor furniture, even synthetic types. If possible, bring your rattan furniture indoors or into a garage or shed.
If you must leave it outside:
Use breathable waterproof covers specifically designed for rattan furniture. Avoid plastic tarps — they trap condensation.
Raise furniture slightly off the ground using rubber feet or tiles to prevent moisture absorption.
Remove cushions and store them indoors in breathable cotton bags.
These small precautions can extend the life of your investment significantly.
Even though synthetic rattan is durable, there are some common mistakes that can cause unnecessary wear or damage.
Avoid pressure washers: The jet can damage the weave.
No harsh chemicals: Bleach or ammonia-based cleaners degrade the plastic.
Avoid wire brushes: They can scratch the synthetic rattan surface.
Don’t dry in direct sunlight: It may cause fading or softening.
Never cover while damp: Moisture trapped underneath can lead to mould.
Stick with gentle cleaning methods, and your furniture will stay looking like new.
If you want to avoid using commercial cleaning products, there are several environmentally friendly options perfect for households in the UK.
Vinegar and water: Great for dissolving grime and disinfecting naturally.
Baking soda paste: Can remove light stains and neutralise odours.
Castile soap: A plant-based option safe for garden furniture.
These DIY solutions are kind to your furniture and eco-conscious — ideal if your garden embraces sustainability.
To preserve that “showroom fresh” appearance year after year, consider these expert maintenance tips:
Clean regularly: Don’t wait for grime to build up.
Protect from strong sunlight: UV rays can fade darker rattan tones. Use parasols or position furniture under shade.
Rotate furniture locations: Even wear prevents fading in just one spot.
Polish occasionally: Use a silicone-based spray to restore shine.
Keep dry: Always check for moisture before covering or storing.
Proper maintenance not only enhances the furniture’s appearance but also ensures greater comfort and longevity.
Over time, UV light can lighten dark-coloured synthetic rattan. Use a UV-protective furniture spray or apply a thin coat of boiled linseed oil (test a small area first).
This is usually caused by loose fittings. Tighten screws and apply a touch of silicone spray on joints.
Exposure to direct heat or storage while wet may cause fibres to distort. Warm the affected area gently with a hairdryer on low heat, then reshape by hand.
When purchasing rattan furniture in the UK, quality makes a huge difference in how easy it is to clean and maintain.
Look for:
High-density PE rattan: More resistant to cracking and UV rays.
Powder-coated aluminium frame: Prevents rust.
UV stabilisers: Protect against colour fading.
Handwoven details: Indicate superior craftsmanship and durability.
