The Scratch That Keeps Getting Longer
A sliding patio door develops a thin scratch down the same section of frame or glass.
Clean it off. Open the door again. The mark gets worse.
Nothing obvious is sticking out of the frame.
The problem can be buried inside the fuzzy seal running along the sliding panel.
That Brush Is Not Just There for Show
Sliding doors commonly use pile or brush seals around moving sections of the frame.
The dense fibres help control draughts, dust and water without creating the heavy friction of a compressed rubber gasket.
They also collect dirt.
And around Bournemouth, that can mean more than the usual household dust.
Patios pick up sand and tiny bits of grit, especially on properties closer to the coast. Once the door starts moving, some of that muck inevitably finds its way into the frame and can work its way between the fibres of the pile.
You often won’t spot it by looking at the seal.
The Seal Turns Into Sandpaper
One trapped grain is enough to cause trouble.
The door slides backwards and forwards while the contaminated pile rubs across the same surface every time.
Fine grit starts marking coated aluminium. Hard particles dragged against glass can leave scratches that ordinary cleaner will never remove.
Spraying lubricant over the dirty seal makes matters worse. Wet products can hold even more grit inside the fibres and create a filthy abrasive paste.
Clean the Seal, Not Just the Track
Don’t just clean the obvious muck out of the bottom track.
Slide the door right back and have a proper look at the brush seals around the frame and where the panels meet.
If there’s grit buried in there, vacuum out what you can first. For anything that’s hanging on, work through the fibres gently with a clean, soft brush rather than flattening them trying to scrub it out.
While you’re there, run your eye over the condition of the pile itself. If parts are crushed flat, torn or have gone hard, cleaning them isn’t going to fix that.
Damaged pile needs replacing with the correct size and backing rather than stuffing a random brush strip into the carrier groove.
Clean the running track separately. Keep oil and heavy grease away from areas designed to stay dry.
Existing scratches will not disappear because the seal has been cleaned. The job is to remove the abrasive material before it creates more of them.
