What to Look For — Buyer’s Guide
What matters
Choose a cleaner that matches the type of dirt on your fascias: everyday grime, algae or weather staining. For uPVC, a non-abrasive formula is best to avoid dulling the finish.
If the conservatory is high or awkward to reach, look for products that work well with extension poles, spray applicators or pressure-washer systems. Always test a small area first.
Our Verdict
The best fascia cleaner is the one that removes the mess without risking damage. For most homes, a good PVCu cleaner plus regular upkeep is enough to keep a conservatory looking smart.
