Taking care of your uPVC windows and doors ensures they stay clean, functional, and long-lasting. Here’s a step-by-step guide on how to maintain your double glazed windows, uPVC frames, and seals to keep everything in top shape.

Basic Cleaning for uPVC Frames

Regular cleaning prevents dirt build-up and keeps your windows looking new. Follow these simple steps:

  1. Use a soft cloth and lukewarm water for routine cleaning.
  2. For more stubborn dirt, add a few drops of mild detergent to warm water.
  3. Wipe down the frames thoroughly, and rinse with clean water to avoid residue.

Avoid:

  • Abrasive sponges or powders (they scratch the surface).
  • Solvents, ammonia, or citrus-based cleaners (they damage the material).

Cleaning Cement, Tile Adhesives, and Paint Stains

After installation, construction materials like cement, tile adhesives, or facade paint can stain your frames. To remove them:

  1. Soak the stain with warm water for 5 minutes.
  2. Use a soft white cloth to gently wipe away the dirt.
  3. Rinse thoroughly with clean water.

For tougher stains, use a specialised uPVC cleaner tested for these surfaces.

Removing PU Foam, Sealant, and Resin Plaster

If there’s PU foam, sealant, or synthetic resin plaster on your uPVC frames:

  1. Carefully scrape off the residue with a semi-hard spatula.
  2. Wipe the area with a damp cloth.

Note: Avoid PU cleaners on coloured frames, as they may cause damage.

Maintaining Double Glazed Windows

Clean the glass panes of your double glazing windows every 2-3 months or more frequently if you live near construction sites or in dusty areas.

  1. Use an alcohol-free glass cleaner to prevent damage to uPVC frames.
  2. Spray the cleaner onto a soft cloth (not directly on the glass).
  3. Wipe the glass gently and avoid letting cleaner run onto the frames.

Caring for Window Seals

Seals ensure your windows are airtight and insulated. Here’s how to keep them in good condition:

  1. Wipe seals with a soft cloth dipped in mild soapy water.
  2. Dry the seals thoroughly to prevent mould growth.
  3. Every six months, apply a silicone-based lubricant to keep them elastic.

Avoid:

  • Solvents, acids, or harsh chemicals that can cause seals to crack.

Regular Maintenance Tips

  1. Clean your uPVC windows regularly when dirt is visible.
  2. For most dirt, a soft cloth and warm soapy water are sufficient.
  3. Rinse off any detergent thoroughly to avoid residue that could burn in the sun.

Products to Avoid

Using the wrong products can damage your uPVC windows and doors. Avoid the following:

  • Abrasive cleaners and sponges (they scratch the surface).
  • Solvents (acetone, petrol, nail polish remover).
  • Ammonia-based cleaners and citrus-scented products.
  • Steam cleaners (they can soften and warp the surface).

By following these simple care tips, you can ensure your uPVC windows and doors remain clean, efficient, and durable for years to come.
