One of the best things about aluminium is how little upkeep it needs — but a quick, regular clean keeps your frames looking new and your windows and doors sliding smoothly for years. The good news is that it’s easy: to clean aluminium windows you only need mild soapy water and a soft cloth, no special products. This guide shows you how to clean aluminium windows and doors the right way, which cleaners to avoid so you don’t damage the finish, and how to keep the tracks and moving parts working.
How to clean aluminium windows: the basics
Powder-coated aluminium is designed to be wiped clean. Two or three times a year, wash the frames down with warm water and a little mild dishwashing liquid, using a soft cloth or sponge, then rinse with clean water and dry with a soft cloth to avoid water spots. That’s all it takes to clean aluminium windows and keep the powder-coated finish looking its best. Homes near the coast or on dusty roads should clean a little more often.
What you’ll need: clean aluminium windows
- A bucket of warm water with a few drops of mild dishwashing liquid
- A soft cloth or sponge (non-abrasive)
- A soft brush or old toothbrush for corners and tracks
- Clean water for rinsing and a dry microfibre cloth
- A squeegee or glass cleaner for the panes
- A light silicone-based lubricant for moving parts
Cleaning the frames: clean aluminium windows
Wipe the powder-coated frames with your soapy water and a soft cloth, working from the top down, then rinse and dry. For stubborn marks, let the soapy water soak for a minute rather than scrubbing hard. The one rule that matters when you clean aluminium windows is to protect the finish: never use abrasive scouring pads, steel wool, or harsh solvent, acidic or alkaline cleaners, as these can dull or damage the powder coat. Mild soap and water is genuinely all you need.
Cleaning the glass
Your windows are glazed with 6.38mm laminated safety glass. Clean the panes with a standard glass cleaner or a simple solution of water with a dash of white vinegar, then finish with a squeegee or a dry microfibre cloth for a streak-free result. Do the glass after the frames so any drips are wiped up last.
Tracks, rollers and moving parts
Sliding windows and doors rely on clean tracks. Brush or vacuum grit and dust out of the bottom track so nothing obstructs the rollers, then wipe it clean — this is the single biggest thing that keeps a sliding door gliding. Add a little silicone-based lubricant to the rollers and moving parts; avoid oil or grease, which attract dirt. While you’re there, check that the small drainage (weep) holes along the bottom of the frame are clear so rainwater can escape.
Coastal and dusty areas
Near the sea, salt in the air settles on frames and glass, so rinse and clean your aluminium windows more often — roughly every month or two — to keep the finish pristine. In dusty inland areas the main job is keeping the tracks clear so sliding panels keep running freely. A little more frequent attention in these conditions goes a long way.
What to avoid
- Abrasive scourers, steel wool or scouring powder
- Harsh solvents, thinners, and strong acidic or alkaline cleaners
- Oil or grease on tracks and rollers (use silicone lubricant instead)
- High-pressure washers aimed directly at the seals and glazing
Frequently asked questions
How do you clean aluminium window frames?
Wash powder-coated aluminium frames with warm water and a little mild dishwashing liquid, using a soft cloth or sponge, then rinse and dry. Avoid abrasive pads and harsh chemicals, which can damage the finish.
How often should I clean aluminium windows?
Two or three times a year is enough for most homes. Clean more often — every month or two — near the coast, where salt air settles on the frames, and keep the tracks clear in dusty areas.
What should you not use to clean aluminium windows?
Avoid abrasive scourers, steel wool, and harsh solvent, acidic or alkaline cleaners, as these dull or damage the powder coating. Mild soapy water and a soft cloth are all you need.
My sliding door is stiff — what should I do?
Usually the track is dirty. Brush and vacuum out grit from the bottom track, wipe it clean, and apply a little silicone lubricant to the rollers. Avoid oil or grease, which attract more dirt.

Specifying clean aluminium windows: what we need to quote
Most of the cost and most of the delay on a project is settled before anything is ordered. If you are specifying clean aluminium windows, the points below move the price, the lead time or the compliance position, so they are worth deciding early rather than on site.
- The structural opening. Measure the brickwork opening rather than an existing frame, and check the reveal is square and plumb.
- Configuration. Confirm the opening arrangement, which panes open, and which way they open before anything is manufactured.
- Colour. Five finishes are stocked — black, white, bronze, charcoal and natural anodised — and some carry a premium.
- Glass. Coetz™ glazes as standard with 6.38 mm clear laminated safety glass.
- Supply only. Aluminium windows and doors are supplied, not installed, so allow for your own installer.
Send those details with your enquiry and we can price clean aluminium windows accurately first time. If something is still open, say so — quoting two options for clean aluminium windows now is far cheaper than altering a manufactured unit later.
