How to Clean Fascias, Soffits and uPVC Without Damage
Quick answer: How to Clean Fascias, Soffits and uPVC Without Damage
Clean uPVC fascias and soffits with warm water, a mild detergent or dedicated uPVC cleaner and a soft brush on a water-fed pole, then rinse. Avoid abrasive pads, solvents and high pressure, which scratch and dull the plastic. Green algae can be removed with a soft wash biocide.
Key takeaways on how to clean fascias, soffits and upvc without damage
- Soft brush and mild cleaner - never abrasives or solvents.
- Water-fed poles avoid ladder work at height.
- Black streaks are often from blocked or overflowing gutters.
- Clean once a year to keep uPVC bright white.
Why fascias go green and streaky
Algae grows on north-facing uPVC, and dirt from overflowing gutters leaves black "tiger stripes" down the front. Clear the gutters first, or the streaks come straight back.
Signs of a bigger problem
Rotten timber behind the fascia, sagging gutters or brown water stains on a ceiling mean water is getting in. Get the roofline checked by a roofing specialist, and read about water-damaged ceilings if stains appear indoors.
Step-by-step cleaning
- Clear gutters of leaves and moss.
- Wet the uPVC.
- Apply a mild uPVC cleaner and brush gently.
- Rinse thoroughly with clean water.
