Step-by-Step Guideline for Caring and Cleaning UPVC Windows

Though Chesterfield is a very beautiful and clean place, that doesn’t mean you don’t have to clean your UPVC windows. You must take care and clean your UPVC windows if you want them to last longer. 

Below is everything in the guidelines that you must know about cleaning the UPVC windows on your own. 

Step 1: Regular Inspection

Frequency: Bi-annually

Purpose: The first step in caring for UPVC windows is to conduct a thorough inspection. This allows you to identify any issues early on, such as cracks, sealant failures, or general wear and tear.

Process: Start by visually inspecting the entire window setup, including the frame, glass, and seals. Look for any visible damage or signs of deterioration. Additionally, check if the windows open and close smoothly without any resistance.

Regular inspections help you catch problems in their early stages, allowing for timely repairs and preventing more extensive damage.

Step 2: Dusting and Brushing

Frequency: Monthly

Tools Needed: Soft brush or microfibre cloth

Process: Dust and dirt can accumulate on UPVC window frames, particularly in corners and joints. To prevent this buildup, regularly dust and brush your windows. Simply use a soft brush or a microfibre cloth to gently wipe down the frames, removing any loose dirt or debris.

Dusting and brushing not only keep your windows looking clean but also help prevent dirt from becoming ingrained in the UPVC material, which can be more challenging to remove later.

Step 3: Cleaning the UPVC Frames

Frequency: Every 3-4 months

Tools Needed: Soft cloth, mild soapy water

Do’s and Don’ts: When it’s time for a deeper clean, use a soft cloth and a mild soapy water solution. Avoid abrasive cleaners or scouring pads, as they can scratch the UPVC surface.

Process: Dampen the cloth with the soapy water and gently wipe down the UPVC frames. Pay extra attention to any areas with stubborn stains or marks. Use circular motions to clean the frames thoroughly. Rinse the frames with clean water and dry them with a separate cloth.

Regular cleaning of the UPVC frames helps maintain their appearance and prevents the buildup of grime.

Step 4: Glass Cleaning

Frequency: Monthly or as needed

Tools Needed: Vinegar-water solution or glass cleaner, squeegee, lint-free cloth

Process: To clean the glass effectively, you can use a vinegar-water solution (one part vinegar to ten parts water) or a commercial glass cleaner. Here’s how to do it:

Spray the cleaning solution evenly over the glass.

Starting from the top, use a squeegee to wipe the glass in a straight, top-to-bottom motion.

After each pass, wipe the squeegee blade with a lint-free cloth to prevent streaks.

Repeat until the entire glass surface is clean and streak-free.

Cleaning the glass not only enhances the appearance of your windows but also improves visibility and natural light intake.

Step 5: Cleaning the Window Tracks

Frequency: Bi-annually

Tools Needed: Vacuum with a nozzle attachment, soft brush, soapy water

Process: Window tracks are often overlooked but can accumulate dirt and debris over time. To clean them:

Start by using a vacuum cleaner with a narrow nozzle attachment to remove loose dirt and debris from the tracks.

Next, prepare a soapy water solution and dip a soft brush into it. Gently scrub the tracks, paying attention to crevices and corners where dirt tends to collect.

Wipe the tracks clean with a damp cloth. Regularly cleaning the window tracks ensures that your windows continue to operate smoothly.

Step 6: Lubricating Moving Parts

Frequency: Annually

Tools Needed: Silicone-based lubricant

Process: UPVC windows often have moving metal parts such as hinges and locks. To keep these parts in good working order:

Apply a silicone-based lubricant to the moving parts. Ensure that the lubricant is spread evenly. Open and close the windows a few times to distribute the lubricant.

Lubricating moving parts prevents them from becoming stiff or corroded, ensuring that your windows open and close effortlessly.

Step 7: Checking and Cleaning the Sealants

Frequency: Annually

Process: Inspect the sealants around the window frames for cracks or gaps. If you notice any issues, clean the sealant with a damp cloth and reapply if necessary. Well-maintained sealants help keep your windows energy-efficient and weather-resistant.

Step 8: Avoiding Common Mistakes

In your journey to care for and clean UPVC windows, it’s essential to avoid common mistakes that can potentially damage them:

Avoid using bleach or harsh chemicals: These can harm the UPVC material and cause discolouration.

Don’t paint UPVC frames: Painting can void warranties and affect the functionality of the windows.

Avoid pressure washing: High-pressure water can damage seals and finishes.

Tips and Tricks For Cleaning Your UPVC Windows 


1.DIY Cleaning Solution

For a budget-friendly and eco-friendly cleaner, mix one part white vinegar with three parts water. This solution works well for both frames and glass, leaving a streak-free finish.

2.Prevent Streaks on Glass

After cleaning the windows, dry them with a microfibre cloth or newspaper. This helps to avoid streaks and leaves the glass sparkling clean.

3.Toothbrush for Hard-to-Reach Spots

Use an old toothbrush for cleaning nooks and crannies in the window frames and tracks. It’s perfect for reaching areas that a regular cloth or sponge might miss.

4.Baking Soda for Stubborn Stains

If you encounter a particularly stubborn stain on the UPVC frame, make a paste with baking soda and a little water. Apply it to the stain, let it sit for a few minutes, then gently scrub it off.

5.Protecting the UPVC Surface

After cleaning, you can apply a thin layer of car wax or a specialised UPVC restorative product to the frames. This adds a layer of protection, making future cleaning easier and keeping the frames shiny.

6.Avoid Direct Sunlight when Cleaning

When cleaning the glass, try to do it on a cloudy day or when the windows are in the shade. Direct sunlight can cause the cleaning solution to dry too quickly, leading to streaks.

7.Use a Vacuum Cleaner

Before washing, use the soft brush attachment on your vacuum cleaner to remove loose dirt and debris from the frames and sills.

8.Silica Gel to Prevent Condensation

Place silica gel packets on the window sills to absorb excess moisture and prevent condensation, which can lead to mould and mildew growth.

9.Check Weather Stripping Regularly

While cleaning, always inspect the weather stripping around the windows. If it’s worn out, consider replacing it to maintain energy efficiency.

10.Gentle Handling of Seals and Gaskets

When cleaning around the seals and gaskets, be gentle to avoid dislodging or damaging them. These components are crucial for the window’s insulation properties.

11.Scheduled Cleaning

Keep a schedule for window cleaning. Regular maintenance is easier and more effective than sporadic, intensive cleaning.
