uPVC windows are a very popular choice amongst homeowners as they are easy to maintain, are durable and help to improve energy efficiency throughout your home. It is essential that when caring for your uPVC windows, you impose a maintenance routine to increase the lifespan of the window and preserve their durability. This also applies when you spill some sealant or silicone on your uPVC windows.

Preparing Your Workspace

Removing Dirt and Debris

Before beginning to clean your uPVC windows, it is important that you remove any loose dirt and rubble from around the frame. For this, you should use a soft brush, or a vacuum cleaner to get rid of any cobwebs and dust.

Removing the loose dirt makes sure that the window’s drainage channels are kept clear. It is important to maintain the condition of the drainage channels as they help to eradicate excess moisture.

Applying the Cleaning Solution

To remove any unwanted marks and stains, dilute some mild detergent (such as washing up liquid) in warm water and using a non-abrasive sponge or cloth, gently scrub the window frames. 

Once you are satisfied with the finish on the window frames, rinse any soap residue away with water and dry thoroughly.

Scrubbing Away Stubborn Stains

On stubborn stains, mix together a solution of white vinegar and water and scrub gently to remove the mark. It is important that after you rinse away any vinegar residue and dry fully.

• Make sure to not use any tools with abrasive surfaces, such as scouring pads or wire brushes, as this will damage the uPVC surface and may leave displeasing scratch marks.

Choosing the Right Cleaning Solution

When cleaning uPVC windows, it is important that you stick to using mild detergents or specially formulated uPVC cleaners as opposed to harsh chemicals.

You should steer clear from using bleach containing products and solvents on your uPVC windows as the chemicals can react with the plastic. This will result in stripping your window frame of its glossy, white finish, leaving behind a matte and sometimes even brown-stained frames. 

Drying and Finishing Touches

Cleaning the Glass 

To keep the glass shiny and streak free, it is advisable to not clean your windows when there is direct sunlight shining on the panes.

• You can use either a commercial glass cleaner, or a homemade solution, made up of white vinegar and water.

• Apply the solution with a lint-free cloth and wipe in circular motions.

• Make sure to dry thoroughly to ensure there are no streaks.

Maintaining the Hardware

To make sure your windows are in the best possible condition, it is important to ensure the hardware is operating smoothly.

• Use a silicone-based lubricant on the locks, hinges and any other moving parts to prevent any rust.
