What is uPVC
uPVC, or polyvinyl chloride, is one of the most widely used plastic materials in the world.
It’s a thermoplastic polymer, which means it can be heated and cooled repeatedly without losing its properties. It is composed of carbon, hydrogen, and chlorine atoms, with the chlorine coming from table salt, or sodium chloride.
Because of its versatility, uPVC is used in a wide range of products, from pipes to toys, floors to cable coatings, and, of course, windows and fixtures in general.
How to Clean uPVC Windows: Step-by-step guide
Cleaning these windows might seem like a task to be done carelessly, but in reality, there’s much more than meets the eye.
Let’s start with the seals and metal parts, often overlooked, but actually crucial to maintaining the windows in excellent condition.
- First of all, you will need 1/2 cup of warm water. This will be the base of your cleaning solution. The next step is to pour a suitable amount of vinegar into the water. Vinegar is a natural and safe cleaning agent that helps remove dirt and stains without damaging the uPVC.
- At this point, soak a microfiber cloth in the vinegar and water solution. The microfiber cloth is ideal for this task, as it’s soft enough not to scratch the uPVC surface, but robust enough to remove stubborn dirt.
- Once the cloth is well soaked, clean the uPVC profile with the cloth. Make sure you gently but effectively rub across the entire surface of the uPVC.
- After cleaning with the damp cloth, now pass a dry cloth over the surface to remove any water and vinegar residue.
- And now, for an additional level of cleaning, put a teaspoon of baking soda in half a cup of warm water.
- This natural cleaning agent is excellent for removing even more stubborn dirt and giving your uPVC windows extra shine.
Take another microfiber cloth and soak it in the baking soda water solution. Pass the cloth over the uPVC surface, ensuring you cover all areas. After doing this, pass a dry cloth to remove any excess solution.
How to Clean uPVC Windows: how to grease the mechanism
Finally, take a dollop of vaseline and apply it to some absorbent paper. This will be useful for greasing the mechanisms and seals of your PVC windows.
Regular application of a little vaseline can help prevent the deterioration of metal components and ensure the smooth operation of your windows.
After following all these steps, your PVC fixtures will be perfect. Not only will they be clean and shiny, but they will also operate smoothly, ensuring lasting efficiency.
Remember, regular maintenance is the key to keeping your PVC windows in excellent condition. Happy cleaning!

Regular care can help extend their life and maintain their efficiency.

Regular Cleaning

As we saw earlier, you can use a solution of water and vinegar, followed by water and baking soda, for a deep clean. Remember to clean both the inside and outside of the windows, including the frame.
Lubrication of Metal Components
Metal components, such as seals and closing mechanisms, should be lubricated periodically.
This can help prevent rust and ensure smooth operation. For this operation, you can use products like vaseline, as seen in the video.
Check Them Regularly
Regularly check your windows to find any signs of damage or wear.
Cracks, distortions, loose seals, or problems with closing mechanisms may occur. If you notice any issue, it’s better to handle it immediately with your dealer to prevent further damage.
Avoid Abrasive Cleaning Products
Avoid using abrasive cleaning products or hard tools can help prevent scratches or damage to the PVC surface. Opt for microfiber cloths and gentle cleaning solutions.
