Maintenance & care
Roller Shutter Maintenance: Keep Them Working for Years
Updated 22 July 2026
Quick answer
Roller shutters need very little upkeep, but the little they need matters. Clean the curtain and guide rails every three months, lubricate the moving parts with a silicone spray about every six months, and book a professional service once a year for anything with a motor.
The single biggest mistake is reaching for WD-40. Use a silicone-based lubricant, never a petroleum product like WD-40. Petroleum sprays attract dust and grit and form a paste that accelerates wear instead of preventing it.
- Who this is for
- Australian homeowners who want their roller shutters to keep running smoothly and avoid premature repairs.
- Key takeaway
- Clean quarterly, lubricate with silicone every six months, and service motorised shutters yearly. Simple habits prevent most of the faults that lead to call-outs.
Roller shutters are built to last 15 years or more, but only if you give them the occasional bit of attention. Grit in the guide rails, a dry motor and neglected slats are behind most of the faults that end in a repair bill. The good news: nearly all of it is quick, cheap and safe to do yourself. This guide covers exactly what to do, how often, and the products to use. Plus the few jobs worth leaving to a professional.

What shortens a roller shutter's life
Grit in the guide rails
Dirt and sand in the guide channels act like sandpaper on the slats and force the motor to work harder every cycle. Regular cleaning is the highest-value habit.
The wrong lubricant
Petroleum sprays such as WD-40 attract dust and turn to a gritty paste. Silicone spray lubricates without holding grime, which is why installers recommend it.
Coastal salt air
Homes near the coast get salt build-up that corrodes aluminium and hardware faster. Coastal properties should clean more often. Monthly to quarterly.
Ignoring small faults
A slight grind, a stiff spot or a slat starting to bend only gets worse. Catching it early during a routine check is far cheaper than a motor or curtain repair.
No annual service on motors
Motorised shutters benefit from a yearly professional service that checks limits, wiring and the motor, issues you can't safely inspect yourself.

Cleaning: little and often
Clean the shutter curtain and guide rails at least once every three months. More often if you're near the coast, under trees, or on a dusty road. The aim is to stop grit building up where it can scratch slats and strain the motor.
- Wipe the slats with a soft cloth and a mild soapy water solution. Rinse gently and dry.
- Never use abrasive pads, harsh solvents or a high-pressure washer. They strip the finish and can force water and grit into the mechanism.
- For the guide rails, vacuum out loose dirt with a narrow nozzle, then run a damp cloth wrapped around a thin tool up and down the channel to lift stubborn grime.
Lubrication: silicone only
Every six months (or more often with heavy use), lubricate the guide rails and moving parts to keep everything running smoothly. Use a silicone-based spray lubricant.
- Do not use WD-40 or other petroleum-based sprays. They attract dust and form a gritty paste that increases wear over time. The opposite of what you want.
- Apply a light, even coat to the guide channels and wipe away any excess. Over-lubricating just collects more grime.
- Cycle the shutter a few times to work the lubricant in.
Regular inspection
Every few months, operate the shutter through a full open-and-close and pay attention:
- Listen for grinding, squealing or a change in motor sound. Early warning of a dry or worn part.
- Watch for the curtain closing crookedly or one side lagging, which points to track alignment or a limit issue.
- Look along the slats for any that are bent, cracked or slipping out of line.
Catch these early and most are a quick fix. Ignore them and they become the faults in our troubleshooting guide.
What to leave to a professional
General cleaning, lubricating and visual checks are all owner jobs. Book a qualified technician for the annual service on motorised shutters, and any time you strike:
- Spring tension problems (a shutter that lifts too easily or won't stay down). Springs are under dangerous tension.
- Motor or gearbox faults, or repeated breaker trips.
- Bent tracks, damaged slats, or a curtain that has come off its guides.
An annual professional service is cheap insurance against a motor replacement, and it keeps most manufacturer warranties valid.
Your seasonal maintenance routine
- 1
Every 3 months: clean
Wipe the slats with mild soapy water and vacuum the guide rails. No high-pressure washers or abrasives.
- 2
Every 6 months: lubricate
A light coat of silicone spray on the guides and moving parts. Never WD-40 or petroleum sprays.
- 3
Every 3 months: test and listen
Run a full open/close cycle and listen for grinding or a lagging side.
- 4
Yearly: professional service
Book a technician to check the motor, limits, springs and wiring on motorised units.
- 5
Coastal homes: clean more often
Salt air corrodes hardware faster. Step cleaning up to monthly.
- 6
Act on small faults early
A grind or a stiff spot is cheap to fix now and expensive to ignore.
