So, you’ve got your stunning VELUX roof windows bringing in tonnes of light into your warm home; however, over time, they got a little messy meaning, you’ll have to clean them. To help out, we have created this short guide on how to clean your VELUX windows safely and correctly to avoid any problems or issues.
You will need:
- Soapy, warm water
- A small amount of light, non-abrasive detergent (if you live in a “hard water” zone, see below)
- Bucket
- Soft sponge or soft cloth
- Non-abrasive drying cloth
- Hand broom
In some areas of the UK, the water is “hard”, that is to say, contains an unusual amount of minerals. This means that it is unsuitable for cleaning windows because it is too abrasive. If you live in a hard water zone (the dark blue on this map) you will need to apply a tiny bit of light, non-abrasive detergent to soften the water.
Cleaning the air filter
Luckily, the air filter can be removed and washed with ordinary household cleaners. To start, fully rotate and secure the window in the cleaning position, then remove the filter from the filter rail. Then you can wash it. Make sure it is dry before replacing it.
Cleaning the pane
To clean the outer pane, rotate the sash 180 degrees. The sash must be secured in position by sliding the barrel bolt into the bushing at the bottom of the side frame. This safety feature leaves both hands free for cleaning. Clean the pane with a soft, clean, lint-free cloth/chamois leather/nonabrasive sponge or a clean, non-metal window squeegee. Clean water will generally be sufficient for cleaning the pane. Ordinary, nonabrasive household cleaners can also be used. Soft water is most suitable for washing panes. Hence, in hard-water areas, add a tiny amount of detergent to soften the water or wipe off all excess water after cleaning.
- Avoid contact from silicone with the pane
- Do not use any cleaning products containing abrasive particles
- Do not use chemical products for cleaning the pane
- Avoid contact with the pane from all sharp or abrasive objects, including jewellery
- Never attempt to clean off dirt on the pane without first applying water
- If any works are taking place in the vicinity of the pane, protect the pane with a clean plastic sheet to prevent any splashes or staining from aggressive and abrasive compounds
Cleaning the flashing
Once per year, leaves and other debris should be eliminated from the flashing around the window to allow rainwater to flow freely. Simply use a hand broom to free detritus from the flashing.
Condensation
When condensation forms on the glazing of your windows, you should take it as a caution sign that you should ventilate more frequently. Regular ventilation is the most efficient way of preventing condensation water from forming on your roof window glazing.
How to limit the amount of humidity
If feasible, do not dry your laundry inside the house as this will help prevent the build-up of condensation. Moreover, close the doors of kitchens and bathrooms. You should also constantly ventilate for five minutes at least three or four times a day. And if possible, sustain a constant room temperature of at least 20°C.
