Clean a Duradek vinyl deck with warm water, a mild household soap and a soft-bristle brush, then rinse it thoroughly. That is genuinely the whole method. Twice a year — spring, and again in autumn once the leaves are down — is enough for most Metro Vancouver decks.
Nearly all the cleaning damage we get called out to look at comes from people trying harder than that: a pressure washer on a narrow tip, a solvent to shift one mark, or a coat of paint over a surface that had years left in it.
The routine, start to finish
- Sweep first. Get the grit off before you add water, or you are grinding it into the wear layer with your brush.
- Warm water and a mild soap. Ordinary dish soap is fine. You are not stripping anything, you are lifting dirt.
- Soft-bristle brush or a push broom. Work in sections. Give stubborn areas more time rather than more pressure.
- Rinse properly. Soap film left behind gets slippery when it rains and collects dirt faster than the deck you started with.
- Clear the drains while you are there. A blocked scupper is how a well-built vinyl deck turns into a pond.
Can you pressure wash a vinyl deck?
Not the way most people do. A pressure washer with a concentrated tip held close to the surface can lift a seam, force water underneath the membrane, and scour the printed wear layer that gives the deck its texture and grip. The damage is often invisible on the day and obvious two winters later.
If you are going to use one: wide fan tip, lowest useful pressure, stand well back, and keep it away from every seam, edge and post base. Honestly, a brush and a garden hose does a better job with none of the risk.
Can you paint Duradek?
No. Three reasons, and the third is the one that costs money:
- It will not stay on. Paint does not bond reliably to a PVC wear layer. It flakes, and it flakes unevenly, so the deck looks worse than it did.
- It voids the warranty. Coating the membrane is a modification to the product. Whatever coverage you had, you no longer have.
- It hides the deck from you. A vinyl deck tells you it is failing through its surface — a lifting seam, a soft patch, a stain spreading from an edge. Paint over that and you lose your early warning while the water carries on.
If the membrane has genuinely aged out cosmetically but is flat, welded and draining, the honest answer is usually to leave it alone. If it has aged out and the substrate is going soft, the answer is recovering the deck — not painting it.
What to keep off a vinyl deck
| Avoid | Why |
|---|---|
| Solvents, acetone, paint thinner | Attack the PVC wear layer directly |
| Full-strength bleach | Can discolour the print and degrade the surface |
| Abrasive powders, wire brushes, steel wool | Scratch off the texture that stops the deck being slippery |
| Petroleum-based products | Stain and soften the membrane |
| Rubber-backed mats left down permanently | The backing can stain the vinyl permanently |
| Dragged planters and furniture | The most common cause of punctures we repair |
For marks that will not come up with soap, Duradek sells a cleaner made for its own membrane. That is the safe choice, because it is formulated not to attack the wear layer — which is more than you can say for whatever is under the kitchen sink.
The ten-minute check that matters more than the cleaning
Cleaning keeps the deck looking right. This is the part that keeps it working. Do it twice a year, when you wash it:
- Walk it barefoot, slowly. You are feeling for soft spots, bounce and dips. Your feet find things your eyes miss.
- Watch it drain. Hose it, or look during rain. Water should leave. Anything that sits is a problem worth solving now.
- Fingernail along the seams. They should be fused flat. A liftable edge is a service call, not yet an emergency.
- Look at every railing post base for lifting, cracking or staining around the penetration.
- Check the wall line where the deck meets the house. Staining on the siding below it means the perimeter detail is leaking.
- Go underneath. Drips, stains, efflorescence on concrete, damp insulation or a musty smell all mean water is already through.
Anything on that list that comes back positive is a substrate question, not a cleaning question. The dividing line between a patch and a rebuild is set out in how long does Duradek last, and if you want to know what the product actually is before you decide anything, start with what is Duradek.
When cleaning is not the answer
VS Deck & Rail is a certified Duradek installer working across Metro Vancouver — Vancouver, North Vancouver, Burnaby, Richmond, Surrey and Delta. A lifted seam or a clean puncture in the field can often be re-welded rather than replaced, and that is a small job if you catch it early.

Frequently Asked Questions
How do you clean a Duradek vinyl deck?
Sweep the loose debris off, then wash with warm water and a mild household soap using a soft-bristle brush or a push broom, and rinse thoroughly so no soap film is left behind. That is the whole routine, and twice a year is enough for most Metro Vancouver decks — once in spring and once in autumn after the leaves come down.
Can you pressure wash a vinyl deck?
Not the way most people mean. A pressure washer held close, or with a concentrated tip, can lift seams, drive water underneath the membrane and damage the printed wear layer. If you use one at all, keep it on a wide fan tip, at low pressure, well back from the surface, and never aim it at a seam or an edge detail. A brush and a hose is safer and usually works better.
Can you paint Duradek?
No. Paint does not bond reliably to a PVC wear layer, so it flakes, and applying it will generally void the manufacturer warranty. It also hides the surface, which means the early warning signs of a failing seam or a soft substrate get covered up rather than spotted. If the appearance has genuinely gone, the answer is recovering the deck, not painting it.
What should you never use on a vinyl deck?
Solvents, acetone, paint thinner, bleach at full strength, abrasive powders, wire brushes, steel wool, and anything petroleum based. Also avoid leaving rubber-backed mats down all year — the backing can stain the membrane permanently. Move planters and furniture occasionally rather than dragging them.
How do you get stains off a vinyl deck?
Start with warm soapy water and a soft brush and give it more time rather than more force. For stubborn marks, Duradek sells a cleaner formulated for its own membrane, which is the safe option because it will not attack the wear layer. Treat any stain that will not lift as cosmetic unless the surface around it is also soft or lifting — then it is a different conversation.
What annual maintenance does a vinyl deck actually need?
Clear the drains and scuppers so water leaves the deck, check the seams by running a fingernail along them, look at the base of every railing post for lifting or cracking, check the wall line where the deck meets the house for staining below it, and go underneath to look for drips or damp. Ten minutes, twice a year, catches almost everything while it is still cheap.
