How to Clean uPVC Windows and Doors at Home: A Simple Guide

uPVC windows and doors are one of the best choices for modern homes in Pakistan. They look elegant, stay clean for years, and require very little maintenance. But just like any other part of your home, they still need proper cleaning every now and then.

If you have recently installed uPVC windows in Karachi or you’re planning to upgrade to the best uPVC doors in Karachi, this step-by-step guide will help you keep them shining and long-lasting.

Why Cleaning uPVC Windows and Doors Matters

Even though uPVC is low-maintenance, dust, pollution, sea air (especially in Karachi), and daily use can build up over time. Regular cleaning keeps your windows:

• Looking fresh and new

• Moving smoothly without noise

• Free from grime or yellow patches

• Long-lasting and durable

• Hygienic and safe for your family
  

A simple 10–15 minute cleaning once a month is enough to keep them in perfect condition.

What You Need for Cleaning (Simple Home Items)

You don’t need anything expensive. Just grab:

• Soft microfiber cloth

• Mild soap or dishwashing liquid

• Lukewarm water

• A spray bottle

• Soft sponge

• Vacuum or small brush

• Old toothbrush

• Glass cleaner

• White vinegar (for stubborn stains)

Avoid using:

✘ Harsh chemicals
✘ Bleach
✘ Hard scrubbers
✘ Acid-based cleaners
✘ Rough cloth

uPVC is strong, but abrasive cleaning can dull the surface.

Step-by-Step: How to Clean Your uPVC Windows and Doors

1. Start With Dusting the Frames

Before applying any water, remove dry dust.

• Use a microfiber cloth or a soft brush.

• Wipe all edges, corners, and outer frame areas.

• For sliding windows/doors, vacuum the bottom track.

This prevents mud or sludge-like build-up after water touches dust.

2. Prepare a Gentle Cleaning Mix

Mix a few drops of dishwashing liquid in lukewarm water.

• This is safe for uPVC material.

• It removes grease, fingerprints, and pollution stains.

• It won’t damage the shine or color.

Pour it into a spray bottle for easy use.

3. Wipe the uPVC Frames

Spray the soapy mixture on the frame and wipe down with a soft cloth.

• Move in circular motions.

• Don’t press too hard.

• Clean both inner and outer sides.

For textured or wood-grain uPVC, use a soft sponge instead of a cloth.

4. Clean the Glass Panels

After cleaning the frame, clean the glass:

• Use a good quality glass cleaner.

• Spray and wipe using a microfiber cloth.

• Move the cloth vertically on one side and horizontally on the other — this helps detect streaks.
  

Pro Tip:
Newspaper can also be used for streak-free glass.

5. Deep Clean Sliding Tracks

uPVC sliding doors and windows often collect dust in tracks.

• Vacuum the tracks first.

• Use soapy water and scrub with an old toothbrush.

• Wipe everything dry.

A clean track ensures smooth sliding and prevents noise.

6. Clean the Rubber Seals (Important!)

Rubber gaskets help keep your room soundproof and dust-free.

• Wipe them with a damp cloth.

• Don’t use harsh cleaners; they may cause cracks.

• Apply silicone spray once every 6–8 months for long life.
  

7. Clean Handles, Hinges & Locks

Metal parts also need basic cleaning.

• Use a soft damp cloth.

• Add a small drop of machine oil to hinges every few months.

• Check if screws are tight.

This ensures smooth opening and closing.

How to Remove Tough Stains From uPVC

If your uPVC has stubborn stains from pollution, rust, or old dirt, use:

1. White Vinegar Mix

• Mix 1 part vinegar + 4 parts water.

• Apply using a soft cloth.

• Leave for 5 minutes and wipe.

2. Baking Soda Paste (Only for tough marks)

• Mix baking soda with water to form a paste.

• Apply very gently.

• Rinse immediately.
  

Avoid rubbing too hard to protect the uPVC surface.

How Often Should You Clean Your uPVC Windows?

Karachi Homes (dusty + coastal air):

Every 3–4 weeks

Other Pakistani Cities:

Every 5–6 weeks

If you live near a main road or construction area, you may need more frequent cleaning.
