How to Restore PVC Windows to Their Original Look After Renovation

After renovation work, PVC windows often bear traces of construction dust, paint, glue or монтажная foam. You can restore their cleanliness without much effort — the key is to act carefully and choose the right products.

Start by removing large contaminants: gently scrape them off with a plastic or rubber scraper to avoid scratching the surface. Then move on to cleaning. For regular dust and light stains, use a warm soapy solution (dishwashing gel or laundry soap) and a soft sponge or microfiber cloth. Wipe down the profile, glass and windowsill, then rinse off any soap residue with clean water and dry thoroughly.

For stubborn stains, treat them spot‑by‑spot:

Construction foam. Fresh foam can be removed mechanically; for any residue, use special cleaners (e.g., PENOSIL Premium Foam Cleaner or “Fenozol”). Avoid acetone and nitro compounds — they can damage PVC.

Glue. Dilute 70 % vinegar with water in a 1 : 10 ratio and gently wipe with the rough side of a sponge.

Paint. Water‑based paint can be washed off with a soapy solution; for oil‑based or acrylic paint, first soften it with a hairdryer, then carefully remove it with a scraper.

Plaster or putty. Moisten the stains for 5–10 minutes, then wipe them away with a soft cloth.

Finally, treat the seals with a soapy solution and lubricate them with silicone grease — this will extend the service life of the windows. Use a soft cloth and avoid abrasive cleaners and stiff brushes: they can leave scratches.

By following these simple steps, you’ll quickly restore your PVC windows to their original shine and cleanliness, preserving their appearance for years to come.
