How do you clean a plastic skylight without scratches? Tips & step-by-step plan

Regularly cleaning your plastic skylight is essential to maintain daylight entry and extend the service life of the material. Whether you have an acrylic skylight or a polycarbonate skylight, with the right approach your dome will stay clear and scratch-free.

Why is cleaning your skylight important?

Dirt, dust and deposits can reduce the light transmission of your dome. Regular cleaning ensures that you make the most of natural daylight and prevents permanent damage to the surface.

Acrylic vs. Polycarbonate: recognize the difference

At Skylux, acrylic skylights are usually fitted with yellow caps, while polycarbonate skylights have red caps . Acrylic is clear and UV-resistant. Polycarbonate is more impact-resistant, but more sensitive to scratches – so caution is required when cleaning.

Step-by-step plan: how to safely clean your skylight

Required items:

• Lukewarm water
• Mild, non-abrasive soap (such as washing-up liquid)
• Soft microfiber cloth or sponge
• Antistatic cleaner (optional)
• Garden hose (pre-rinsing)

Steps:

1. Preparation: Rinse the dome with a garden hose to remove loose dirt.
2. Cleaning: Mix lukewarm water with a little mild soap. Use a soft cloth or sponge to gently clean the dome.
3. Rinsing: Rinse the dome thoroughly with clean water to remove soap residue.
4. Drying: Let the dome air dry or use a clean, dry microfiber cloth.

What should you avoid?

• Do not use scouring pads or hard brushes – these cause scratches.
• Avoid aggressive cleaning agents such as acetone, ammonia or methylated spirits.
• Do not use a pressure washer – this can cause damage.
• Do not clean in direct sunlight – this can cause streaks or stains.

Maintenance tips

• Clean at least twice a year for optimal daylight.
• Check for cracks or damage while cleaning.
• If necessary, use an anti-static cleaner to reduce dust adhesion.

With these guidelines, your Skylux skylight will stay clear and functional. Regular maintenance ensures optimal daylight and significantly extends the service life of your dome.
