Tips for Keeping Your PVC Windows, Doors, and Conservatories Looking Like New


The grained foiled finishes are also available inside, but white UPVC is more popular because it is less noticeable and more straightforward to clean than the other options.

The foils are available in several finishes, including Oak, Mahogany, Rosewood, and the recently introduced custom colors. Some color options include Irish wood, rustic cherry, and many grays, reds, and blues.

Different ways to clean a window frame depending on the finish the customer selected. However, regardless of which PVC items are installed, routine maintenance on the product’s functional components and general principles will remain the same.

Customers had PVC installed 18 years ago, which could have an aesthetic impact. With the correct tools and supplies, the PVC panes of your windows and doors should look as good as new again.

The performance of the glass will not be as effective as the new heat-efficient windows and doors currently being installed, but there are a few ways to bring antique windows back to life. Handles and locking systems, for example, need to be serviced every three to six months to prevent failures and keep you hassle-free.

Simple tidying up.

When the windows are opened, a channel containing the hinges and locking keeps becomes visible. Loosen the dirt with a small brush and a vacuum to get rid of the bulk of it.

We recommend a nonabrasive cloth and soapy water for routine maintenance for cleaning PVC windows. Wash the inside and outside of the window with soapy water (a regular non-bleach detergent). After cleaning, use a fresh cloth to dry the entire frame. While the channel is open, use a soapy towel to wash down the inside and clean the rubbers.

There will be a 5 mm dirt line around the opener where it shuts onto the window frame; this must be removed with a soapy cloth.

It’s also a good idea to wipe down the area along the top and sides of the window opener. If you pull the opener out as far as it goes, the access point will be revealed at the top.

The glass cleaner or solvent we recommend further down will remove any sticky markings from the PVC frames or glass you have been unable to remove.

If you splatter glass when decorating and leave microscopic specks, you can remove them using a Stanley knife’s flat, sharp blade or something similar. If there are any stubborn marks on the glass, you can use a blade to remove them, but be careful not to scratch the glass in the process. Take your time and use it as flatly as possible. Avoid this method or hire an expert if you are unsure about your abilities.

Cleaning fluids, lotions, and aerosols

What you put on a PVC window or door depends on its color and age. Which cleaning product you’ll need depends on how much dirt and grime have settled into the surface.

The above cleaning should be sufficient if the window is white PVC and not too old.

If you need to apply something besides soapy water, you should always use an industrial paper roll you can get at your local PVC retailer. Alternatively, you can use high-quality kitchen towels for the window casings, although this is not recommended for the glass. (discussed below)

Outdated glass and frames

If the window is older and needs more prodding, try a PVC cream cleaner from a reputable DIY store. The cream should only be used on the white PVC, not the glass. Remember to use another sheet to remove any surplus. After that, you can use a solvent to give it a polished final look.

A bottle of high-quality PVC cleaning from a home improvement store or a PVC distributor is invaluable. Get their input on what you need and what items to use. This can be used to clean up any remaining dirt or scratches in your white PVC window frame. Avoid wiping away any silicone, please. Start with a small amount of the solvent and work up to remove the silicone. This is the best technique to remove the stain if your silicone has gotten yellow from cooking or smoking.

Grain patterns in wood and custom paint jobs

Wood grain or custom colors can be maintained with a quick oil spray, like WD40. It will improve the final product and provide some protection for the window. It will lessen the sticking power of future dust and bird droppings. If your surface has a foiled finish, only use this method to clean it. Cleaning spray oils will not help white PVC windows at all. Apply the spray generously on the roll and wipe in sweeping movements, but avoid getting the rush on the glass.

Repairing Handles, Locks, and Hinges

Managing this is easy if you have a spray oil like WD40. This upkeep must be performed every three to six months for trouble-free operation of windows and doors. These days, brochures with maintenance tips are standard issues for installation crews. In that case, seek their counsel.


Apply some oil to the key and insert it into the handle lock. To insert the key, jiggle it and then push it about five times. Use the spray can’s straw nozzle to force some through the handle lock if you don’t have the key. These locks might become slightly stiffened by moisture. The moment the lock is loosened, you will feel it. These rooms will reap the most significant benefits because of the high humidity and constant opening of kitchen and bathroom windows.

Security locks

When you open the window sash, you’ll notice a set of lock keepers at the bottom of the channel. It won’t hurt anything to spray these down quickly. Feel under the device to find the locking mechanism and roller cams that engage the lock keepers when the opener is closed. It is necessary to coat the entire locking strip, usually done from the inside. If it doesn’t work, go around the outside and spray everything down.

You may prevent future access issues by spraying the key inside and outside your PVC doors. The locking strip is located in a groove on the sash opener’s side, visible when the door is opened from the handle side. This is the first thing to deteriorate even before the doorknobs and handles. This must be sprayed when the door handle is down (hooks in) and up (hooks out) in the open position. Shoot bolts will be exposed while the system is locked; they should be sprayed with oil to prevent the mechanism from freezing.

To prevent significant friction from slight rusting, spray the hinges of the open PVC door. PVC doors and conservatory windows follow the same general cleaning guidelines outlined for windows.


When a window is opened, the hinges slide into a groove cut into the frame. The hinges will expand as the window is opened, making them simple to spray. There should be a tightening screw on the hinge so that it may be tightened back up after being loosened by the spray each time it is maintained. After the glass unit, PVC window hinges are the most often replaced parts. If not treated, the dampness and moisture accumulated over the year will corrode the hinge. This is the busiest portion of the window and supports the sash, so ensure it stays in good shape. In the salty air of the coast, rust can spread rapidly.

Glass washing

Every window installer has been asked this at some point throughout their career. How do you keep the windows streak-free? The short answer is that no magic is involved, and the only key is to use a commercial glass cleaner that does not leave streaks.

A specially designed paper roll should be applied instead of using a kitchen towel or toilet paper. This is because the cheap rolls will shred and leave fibers all over the window. You must apply the solution directly to the glass and work it into the crevices.

To remove it from the window, wipe it vigorously with the roll. Flip the roll over once the glass is dry and buff it to a mirror finish. The exact process must be repeated on the exterior for the best glass polish.

If there are any sticky marks, it is OK to use a solvent cleaning first. The glass can be cleaned with a solvent without risk. Use the glass cleaner to restore the luster after that.

Getting the ideal Polish on your glazing may seem impossible if you use old-fashioned methods like vinegar, water, or other questionable ideas. However, this is not true if you purchase a professional grade from a reputable PVC supplier.

Maintenance and cleaning procedures for PVC windows, doors, and conservatories are all the same if they all have the same finish.

If you are unsure of any of the above or lack self-assurance in your abilities, consult your local do-it-yourself store for guidance. All suggestions above require common sense, as failure to adhere to them could damage your double glazing.
