How to Clean Outside Windows

To clean the outside of windows, wash the glass with warm soapy water and pull a squeegee down in overlapping strokes on anything you can reach, then dry the edges with a microfibre cloth. For high or second-storey windows, the safe way is a water-fed extension pole with purified water, which cleans and rinses the glass spot-free from the ground with no ladder. The rule for exterior glass is to avoid a tap-water final rinse, because its minerals dry into spots.

Outside windows are harder than inside ones. They cop weather, dust, pollen and hard water spotting, and the worst of them are two storeys up and out of safe reach. This guide covers the method for exterior glass, how to do the high windows without risking a ladder, and how to deal with the hard water spots that plague outdoor windows.

The short version:

• Reachable glass: soapy water, squeegee top-down, dry the edges.
• High or second-storey: a water-fed pole with purified water, from the ground.
• Final rinse: purified water, not tap water, to avoid mineral spots.
• Out of safe reach: use a pole or call a pro, never overreach off a ladder.

How do you clean outside windows?

For exterior glass you can reach, the method is the same streak-free routine as inside, just with more washing because there is more grime. Dust and cobwebs come off first, then a wash with warm soapy water, then a squeegee pulled from the top down with the blade wiped dry between strokes, and finally a dry microfibre around the edges. Work out of direct sun so the glass does not dry before you wipe it.

How do you clean high or second-storey windows safely?

The safe way to clean high windows is a water-fed extension pole used from the ground, not a ladder. The pole carries purified water up to a soft brush head, which scrubs and rinses the glass, and because the water is purified it dries with no spots and needs no wiping. Poles reach second-storey windows comfortably, so you clean the whole home standing safely on the ground.

Ladders are where window cleaning goes wrong. Falls from height are one of the most common causes of serious injury around the home, and reaching sideways off a ladder to a window is exactly the move that causes them. If you do not have a water-fed pole and the window is above ground level, that is the point to stop and either buy the right gear or hand it over. One customer in Melton had been doing their upstairs windows off an extension ladder for years until a slip convinced them otherwise, and now has them done from the ground in one visit.

Why do outside windows get hard water spots?

Those white, cloudy spots on outdoor glass are dried mineral deposits, left behind when tap water, sprinkler spray or rain runoff dries on the window. The water evaporates and the dissolved minerals stay put, building up over time into a haze that ordinary cleaning does not shift. Light spotting comes off with a 50/50 white vinegar and water solution left to dwell and then squeegeed off. Heavy, long-standing deposits may need a dedicated hard water stain remover.

The way to stop them coming back is to change the water, not just the cloth. Rinsing with purified or deionised water, which is what a water-fed pole uses, leaves nothing behind to dry into a spot, which is why professionally cleaned outdoor glass stays clear longer than a hose-and-tap-water clean. Keeping sprinklers off the windows helps too.

Can you clean outside windows from the ground?

Yes, and for anything above the ground floor you should. A water-fed extension pole lets you wash and rinse exterior windows, including second-storey ones, without ever leaving the ground, which removes the ladder risk entirely. For ground-floor windows a normal squeegee and cloth are fine, but the higher glass is exactly where a pole earns its place, both for safety and for the spot-free finish the purified water gives.

When should you call a professional for outside windows?

If your home is double storey, the windows are large or awkward, or you do not have a water-fed pole, the outside glass is worth handing to a professional. A pro cleans the high windows safely from the ground, gets a spot-free finish with purified water, and clears hard water staining that household cleaning leaves behind. It is also simply faster, since the right pole and purified-water setup does in one visit what a ladder and a bucket struggle with.

That is a core part of what we do.

Common questions about cleaning outside windows

How do you clean outside windows you cannot reach? Use a water-fed extension pole, which cleans and rinses from the ground and reaches second-storey glass, or have them done professionally. Never overreach off a ladder to a window, since that is where the serious falls happen.

What is the best way to clean outside windows without streaks? Wash with soapy water, squeegee top-down wiping the blade each stroke, and finish the edges with microfibre, all out of direct sun. For high glass, a water-fed pole with purified water dries spot-free with no wiping at all.

How do you get hard water stains off outside windows? For light spotting, a 50/50 white vinegar and water mix left to dwell then squeegeed off usually works. Heavy deposits may need a dedicated hard water stain remover, and rinsing with purified water afterwards stops them returning.

Can you clean second-storey windows without a ladder? Yes. A water-fed extension pole reaches second-storey windows from the ground, which is both safer and gives a spot-free finish. It is the standard method professionals use for exactly this reason.
