UPVC window frames are a fantastic low-maintenance choice for any property – but over time, they can still become dull or discoloured. Pollution, algae, grime, and even limescale can build up on the surface, taking away that bright, fresh look. With the right routine and a few simple tools, it’s easy to restore your frames and keep them looking great for years to come.
What You’ll Need
Before you begin, gather these essentials:
🧼 Warm water
🧴 A splash of washing-up liquid
🧽 Microfibre cloth or non-abrasive sponge
🪥 An old toothbrush for corners and tight spots
🧪 Optional: A specialist UPVC cleaning fluid for stubborn stains
Step-by-Step: How to Clean UPVC Window Frames
1. Start with a Dry Wipe
Brush off dust, cobwebs, and loose dirt using a dry cloth or soft brush. This helps prevent smearing once you start cleaning with water.
2. Wash with Soapy Water
Mix warm water with a little washing-up liquid. Use a soft cloth or sponge to gently wipe the frames – paying extra attention to grooves, edges, and hidden areas.
3. Tackle Stains or Yellowing
If your UPVC has older marks or discolouration, a dedicated UPVC cleaning solution can help. These are formulated to cut through oxidation and stubborn build-up without damaging the surface.
