PVC Windows: Rules for Perfect Cleanliness

Clean windows let in maximum light and enhance your interior, but careless cleaning can damage the profile, glass, and seals. Here’s how to achieve a flawless result without unwanted consequences.

Gather your tools. You’ll need:

• a soft cloth or microfiber wipe;
• a sponge without an abrasive layer;
• a rubber squeegee (for glass);
• a neutral detergent (free of acids, alkalis, and solvents);
• warm water.

Start with the frames. Dip the cloth in soapy water and gently wipe the profiles, paying special attention to corners and joints. Avoid pressing too hard — plastic is prone to scratching. Pay extra attention to the drainage holes at the bottom: remove dirt with a thin stick.

Move on to the glass. Apply the cleaning solution and spread it evenly with the squeegee from top to bottom. This helps avoid streaks. For hard‑to‑reach areas (e.g., between double‑glazed units), use a telescopic microfiber brush.

Don’t forget the seals. Wipe them with soapy water, then dry with a soft cloth. Never use alcohol solutions or gasoline — they damage the rubber.

Tend to the hardware. Use a lightly dampened cloth to remove dust from hinges and handles. If there are stubborn stains, use soapy water, but avoid letting moisture into the mechanisms.

Finish with drying. Go over all surfaces with a dry microfiber cloth to remove any remaining moisture. This prevents water spots and residue.

Important prohibitions:

• don’t use stiff brushes, metal scourers, or abrasive powders;
• avoid hot water (above 40 °C) — it can deform the plastic;
• don’t use products containing chlorine, acetone, or acids;
• don’t polish the profile with alcohol‑based solutions.

Cleaning frequency depends on conditions:

• in city apartments — 2–4 times a year;
• near roads or construction sites — every 2–3 months;
• after renovation — immediately upon completion.

By following these rules, you’ll keep your windows looking like new: free of scratches, clouding, and seal damage.
