How to Clean Garden Furniture Safely (Patio Set Guide): Questions Answered
Skip the long read: here are quick, straight answers to the questions UK beginners most often ask about how to clean garden furniture safely (patio set guide), with links through to the full guides.
Is it safe to use a pressure washer on my garden furniture?
Pressure washers work fast, but on a concrete patio they create a problem that is harder to fix than the grime. The runoff drives dirt and cleaning chemicals straight into the porous surface, causing efflorescence and permanent staining. Most UK gardens sit on concrete slabs or paving stones, so that “quick clean” can leave you with a stained patio and furniture stripped of its finish.

Can I use bleach to remove green algae and mould?
Bleach makes the surface look clean, but it does not fix the root cause of the problem. In a damp UK winter, that clean-looking result does not hold, and the green creeps back within weeks because the organism was never actually dealt with. You need an approach that deals with the organism rather than just the colour to stop it re-establishing. Full details in our guide to Green Algae and Mould on Garden Furniture: What Actually Works.
Will pressure washing damage my rattan furniture?
Pressure washing on the wrong setting forces water into rattan weave joints and can lift the adhesive bonds that hold the furniture together. High-pressure water applies force to the surface it hits, which can damage rattan more than it helps. The honest answer is material-specific, and it hinges on one question most guides never ask: what is the water actually doing to the surface underneath the dirt.

How do I clean outdoor cushions without ruining the foam?
Most outdoor cushions are salvageable, but the reason they go to pot is usually what happens underneath. Every guide tells you to strip the covers and wash them, but almost none tell you what to do with the foam inside, and that is where the real failure happens. You need to know exactly which cleaning path fits your cushions and how to dry them properly so they do not smell worse by autumn.

Should I replace my garden furniture cover or clean it?
Replacing a garden furniture cover typically costs £30–80, while cleaning one costs about £2 in bleach and half an hour of your time. The mould that wrecked the look of your cover almost never means the fabric itself is finished. What actually failed, in most cases, is a habit rather than the material — putting the cover back on furniture before it was properly dry.

What is the best way to clean general garden furniture?
For a one-off seasonal clean after winter or when grime has built up, washing-up liquid and warm water is the material-specific method that protects both the furniture and what it sits on. Universal cleaning advice fails because teak, rattan, powder-coated metal, and plastic each respond differently. A bleach-based solution will strip a teak table’s natural oils, and the same bleach on white plastic furniture turns it yellow and brittle.

Why does green mould keep coming back on my patio set?
Algae and mould are living organisms that attach themselves directly to surfaces such as wood, metal, plastic, and resin-weave materials. They do not sit on top of the surface; they bond with it. What makes this worse in the UK is the combination of damp, shade, and limited airflow, which provides exactly the conditions the organisms need to thrive.

Is it okay to pressure wash plastic garden furniture?
Pressure washing on the wrong setting forces water into rattan weave joints and can lift the adhesive bonds, but the same applies to plastic furniture. The confusion isn’t your fault, as manufacturers are inconsistent: some care guides say pressure washing is fine for plastic, others say don’t even think about it. The honest answer is material-specific, and it hinges on one question most guides never ask: what is the water actually doing to the surface underneath the dirt.

My cushions smell damp after winter, how do I fix that?
You have brought the rattan set out for the first time this spring, and the cushions smell like a damp wardrobe. Not quite mould, not quite mildew — just that musty undertone that creeps in after a UK winter under a cover that was not doing its job properly. The honest answer is that most outdoor cushions are salvageable, but you need to know how to wash them without wrecking the filling. Full details in our guide to How to Clean Outdoor Furniture Cushions Without Ruining the Filling.
Can I put my garden furniture cover in the washing machine?
Most garden centres stock covers in one of three fabrics: polyester, polypropylene, or PVC. Polyester and polypropylene dominate the mid-range — lighter, easier to handle, and more breathable than PVC. A decent cover should give three to five years of service if it is looked after properly, and a couple of cleans a year can stretch that further. Full details in our guide to Garden Furniture Covers: Clean vs Replace Decision.
What happens if I pressure wash my wooden garden table?
Pressure washing on the wrong setting forces water into rattan weave joints and can lift the adhesive bonds, but it also applies force to the surface of wood. On a teak dining table, that force lifts the wood grain, causing the fibres to swell and splinter slightly. The honest answer is material-specific, and it hinges on one question most guides never ask: what is the water actually doing to the surface underneath the dirt. Full details in our guide to Pressure Washer on Garden Furniture: Yes or No by Material.
How do I stop mould growing on my cushions again?
The reason they go to pot is usually what happens underneath the fabric. Every guide tells you to strip the covers and wash them, but almost none tell you what to do with the foam inside, and that is where the real failure happens. You need to know exactly which cleaning path fits your cushions and how to dry them properly so they do not smell worse by autumn.
