Short answer
Sliding patio doors and bifolds are cleaned like windows: pure water and a brush outside, washer and squeegee inside. The difference is the tracks, which collect grit, leaves and dirt. Vacuum loose grit from tracks first, then wipe them with warm water. Never drag grit across the glass when cleaning, because it can scratch.
Why do patio doors get so dirty?
They’re used every day, low enough for children and pets, and next to the garden. Handprints and nose prints inside, splashes and soil outside. Large panes also show every mark, especially in low sun.
How do you clean the outside?
The same as any window: pure water through a brush on the glass, then rinsing. Ask me about frames and sills. Because the glass is at ground level, I can see the whole pane closely. Pure water dries clear, so I don’t wipe it. Is pure water window cleaning better?
How do you clean the inside?
By hand, with a washer and squeegee, with a cloth down on the floor. Large panes are done in overlapping strokes so no water is left to dry. If there’s furniture or a rug in the way, I’ll ask before moving it.
What about the tracks?
Tracks are where sliding doors collect grit, sand, leaves and dead insects. That grit can make the door stiff and wear the runners. Between cleans, you can:
- Vacuum loose grit with a narrow nozzle.
- Brush out what’s left with a small, stiff brush.
- Wipe with warm water and a little mild washing-up liquid.
- Dry the track so water doesn’t sit in it.
Check the door maker’s guidance before using lubricants or sprays on the runners.
What about drainage holes?
Many door and window frames have small drainage slots in the bottom of the frame that let water out. If they block with dirt, water can sit in the frame. A gentle clear-out with a soft brush or a pipe cleaner helps. Don’t force anything sharp into them.
What about bifold doors?
Bifolds have more frames, hinges and gaps than sliders, so there’s more to clean around. The tracks need the same care. The glass is cleaned the same way.
Are patio doors included in a window clean?
In my outside clean, glass in doors is included where I can reach it, and patio doors usually can be. For insides, they’re part of the rooms we agree. Tell me about them on the quote form.
What about scratches?
If you see fine scratches on patio glass, they may have come from grit being rubbed across it at some point. Cleaning can’t remove scratches. Wetting glass before cleaning, and rinsing rather than rubbing, helps avoid new ones.
How do I clean patio glass myself between visits?
If handprints on the inside bother you between cleans, a simple method works:
- Wet a clean microfibre cloth with warm water and a drop of washing-up liquid.
- Wipe the marked area, working from the top down.
- Dry it straight away with a second, dry microfibre cloth, so the water doesn’t dry into spots.
Avoid kitchen roll on large panes; it can leave lint. Avoid glass sprays near seals if your door maker advises against them.
What about the frames and handles?
Door frames are touched more than window frames, so they collect grease around handles and locks. Warm water with a little mild washing-up liquid on a soft cloth is enough for uPVC and aluminium. Dry the handles afterwards. Leave the lock mechanisms themselves to the door maker’s advice.
Why do sliding doors get stiff?
Usually grit in the track or worn runners. Cleaning the track often helps. If it doesn’t, the runners may need adjusting or replacing, which is a job for a door fitter, not a window cleaner.
What about the seals?
The rubber or brush seals along the edges of sliding doors keep out draughts and rain. They collect dirt too. A soft brush and a damp cloth are enough; avoid pulling or soaking them.
Common questions
Do you clean the tracks?
Ask me about frames when you book. Deep track cleaning is something you can do between visits, using the steps above.
Can you clean doors with integral blinds?
Yes, the outer glass is cleaned the same way.
What about the glass in my front door?
Included where I can reach it.
Do patio doors need cleaning more often?
Often, inside especially, because they’re touched so much. How often is up to you.
