Before You Start: Collect Your Materials

Broadly speaking, using the right tools makes the work both efficient and safe. In this case, you will need:
- Soft cloths or sponges. Use lint-free garments such as microfiber towels so that the uPVC does not get scratched.
- Dish soap or dedicated uPVC cleaner. Prefer filling a bucket with warm water and a few drops of dish soap to lukewarm water. Avoid boiling water as it can warp the window frames.
- Soft bristled brush or old toothbrush. This is for small grooves, corners, or hinges where dust settles.
- Baking soda or white vinegar (optional). For persistent stains, natural cleaners can be effective—like spray 1:1 white vinegar solutions to mitigate mildew.
- Protective gloves. Used during scrubbing or cleaning tasks to safeguard hands.
- Sprayer and bucket (optional). Handy for focusing on certain areas with liquid and collecting soapy water respectively.
- Chamois or squeegee. A squeegee offers streak free finishing while removing excess water from glass surfaces (inclusing newspaper buffing for shine).
- Vacuum cleaners equipped with a dust collector as well as a brush are useful for dry cleaning the frames and dust marks.
Always gather everything you require before starting. Abrasive pads and chemical solvents should never be used on uPVC, as they will cause irreversible damage to the surface.
Step-by-Step Cleaning Procedure
Removing Loose Dust and Debris
Start with a dry pass. Use a soft brush or cloth to wipe or vacuum the frames, sills, and tracks free of any loose dirt, leaves, and cobwebs. Make sure to attend to corners and grooves as dirt in these areas can scratch the PVC during washing. Take care with hinges and seals, vacuuming away gritty build-up.
Creating The Cleaning Solution
Pour a small quantity of detergent into a bucket filled with lukewarm water. This constitutes the cleaning solution for the procedure. For more difficult spots, having a spray bottle filled with diluted cleaner handy serves an additional purpose. Strong alkali or acidic cleaners should be avoided—stick to gentle soaps instead. Do not use bleach, acetone, methylated spirits or ammonia-based cleaners as these substances will mark or discolor uPVC permanently. Also avoid hot water which can warp old PVC.
Wash the Frames
Soak a soft cloth or sponge in soapy water, then wring out any excess water. Start from the top of the frame and wipe it down fully while preventing dirty drips from staining the clean areas. Gentle circular motions are best for greasy grime like fingerprints or tree sap. If lightly spraying the frame off with a garden hose first is an option, that can assist in removing some dirt as well.
Rinse Thoroughly
After scrubbing, frames should be rinsed with clean water either via hosing gently or wiping with a fresh cloth dipped into plain water. It’s important to wash off soap residue entirely due to leftover detergent leading to dirt attraction resulting in streaks on the frames.
Dry and Buff
Spotting missed portions is easier when drying fully on areas such as towels ensures no excess water results in unsightly spots left behind, lint-free towels also contribute toward spots being eliminated entirely. Shiny surfaces can be achieved through buffing. Crystal clear panes can also result from face washing ash glass using a rubber squeegee followed by polish through dry cloth around frame edges.
Admire the outcome and give the frames one last polish after the cleaning is completed. Your uPVC should look fresh and bright with a polished glow after being thoroughly dried.
Tackling Stubborn Stains and Mould
In some cases, additional effort may be necessary:
Baking Soda Paste
Make a paste of water and baking soda for tougher stains like bird droppings. Apply to the soiled area and gently rub using a damp cloth then rinse fro clean. The mild abrasive action enhances dirt removal without scratching surfaces.
Vinegar Spray
Use equal portions of vinegar and water in a spray bottle to treat black mold or mildew on the frame. Lightly mist the affected surfaces, leave it for 10 minutes, scrub with soft brush, then rinse and dry well. Take note that vinegar safely neutralizes many types of mould spores as well.
Upvc cleaning fluids that are also bleach free are dedicated products that can remove discoloration.

What Should Not Be Used On uPVC
- Chemical agents such as bleach or ammonia-based cleaners are harmful to PVC. Thus, for maintaining your frames safely, do not use these products.
- Your plastic frames may be scratched by abrasive scouring pads or sponges, which include steel wool and kitchen scourers.
- Acetone and paint thinners also fall under solvents that melt or cloud the uPVC.
- Gentle hosing is preferred over high-pressure washing as power washers can warp frames and force water under seals.
- While using dark dyes is not an issue for many, they do transfer onto white frames. Cleaning or lightly tinted cloths should always be used alongside prep sponges to avoid staining from dark dyes.
If you ever feel uncertain, remember milder than soap water solutions are always safe.
Final Assessments and Routine Cares
Many issues can be averted by routine care after cleaning. In this instance we recommend:
- Add a few drops of silicone spray or light oil to window locks and hinges – this aids in rust prevention and ensures the window opens smoothly making it user-friendly.
- Check seals along with hardware for gaps or cracks around the frame including worn out seals which let moisture indoors – spotting such problems requires a prompt repair strategy.
- Examine frame condition. uPVC is durable, but like all materials, suffering from gouging or old abrasive cleaning methods can permanently damage the surface finish. Do not repaint, or drill into the un-primed and unscrewed uPVC frames as that would void the warranties.
- Remove any stickers promptly. Stickers or glue residue should be removed using warm soapy water to make them pliable in order to prevent painted walls from peeling off when these are removed.
- Regular gentle cloth wipe. Dust settles within frames between thorough wiping sessions, and a monthly damp cloth quick wipe accelerates this ongoing care and prevents build-up.
Completing these will improve tight window sealing with improved dirt free clean framing construction that enables flawless draughtless closing. Damp air cannot penetrate your home.
