One of the things homeowners love the most about fiberglass windows is that they don't need much maintenance. But while they require very little maintenance, even the highest quality window material can still get dusty and dirty. If you want to improve the longevity of your fiberglass windows so that you can enjoy them for years to come, you should make sure to clean them regularly. Regular cleaning makes sure you get the most out of your investment. This is true even many years after installation.

When buying a replacement window, fiberglass is one of the best options. It has a number of advantages over other materials like vinyl, including its ability to withstand extreme weather conditions. As any window replacement company or window manufacturer will tell you, preserving the beneficial properties of fiberglass requires a little care. 

If you currently have fiberglass windows installed and you plan on cleaning them in your home in San Diego, or you recently moved to a home with fiberglass windows, here's a quick cleaning guide on how to clean your windows to help you keep them in top shape.   

Step 1: Scrub Large Debris

Look at the window to find any signs of leaks, deformations, rot or damage, so that you can prevent major problems. If your water is too soapy, it can seep into the cracks, leaving stains, mold, and other issues. The biggest tip here is to work in a dry environment so that no water drips through the frame. Without getting into a cleaning solution, use a soft, bristly broom on the outside of the window to remove dust, dirt, and anything else that sticks to the surface, such as cobwebs, dead bugs, and other loose material on the window frame. Use a vacuum to remove the dust and wipe the surface with a dry cloth.

You will also need to remove the window screen as it also needs to be cleaned regularly. After all - it catches most of the dust and vermin outside and prevents them from flying into your house, and helps reduce the amount of dirt and pollen that invade your home. Remove the screen to prepare for cleaning. When you remove the screen, place it on a dry flat surface. Apply a cleaning solution and let it dry.  Take the screen outside and let it dry completely for at least a few hours before placing it back on your window. Make sure you keep your screen somewhere safe and dry.

Step 2: Rinse 

It is important to start with the right detergent and use it to clean your windows. Using a hard detergent or wiping material could scratch or otherwise damage the glass.

We recommend a detergent that is gentle and non-abrasive and using a soft cloth to remove dirt on the windows. Use a soap that is specifically made for home use, and mix it with water and using only a small amount. To avoid the need for a strong detergent, you should repeat the process until the dirt is removed and wash them again with water.

Using a detergent or any other washing liquid is good enough in almost all cases. You will want to stay away from abrasives, hard chemicals, and solvents. Simply wiping the windows with soap and warm water and then drying them with a cloth is probably one of the easiest and safest ways to clean them. The more you clean your windows on a regular basis, the harder it becomes for tough stains to collect, and the easier it will be to clean them.

You should never use a blade to scratch off stains on your fiberglass windows, as this can really damage the glass's special coating surface. For those who have the most persistent stains, you may feel compelled to use a stronger cleaning solution. Typically, the best and obvious choice for cleaning fiberglass windows is a cleaning product that is safe to use on them but it can sometimes be a challenge to determine which ones won’t damage your windows. You can make your own window cleaning solution by simply using distilled vinegar. A vinegar-water solution is one of the simplest and easiest window frame cleaners you can use for fiberglass windows. This non-abrasive household cleaner can be used to brighten up your windows as a glass cleaner or simply as a general-purpose cleaning product. If you opt for another type of cleaning product, check your cleaning solution to see how you should dilute it if necessary, and then follow the instructions to get it ready for use. Apply the cleaning solution to a soft cloth and gently wipe the surface of the window frame. If you are unsure which cleaning agent is right for your windows, contact your local window cleaner or professional window cleaner. They can advise other products that will be safe for your fiberglass window frames if stains remain.

Make sure to rinse away any cleaning residues with fresh water and a squeegee, and use a bowl of warm water and detergent. Next, use the same warm, soapy water, and go through the frame and rinse it again with a clean cloth or newspaper. Use a little soft scrubbing to avoid scratches and abrasions. 

Once the frame is clean, go through the glass and wipe the glass with a damp cloth. From here, you can use a standard glass cleaner or make your own solution from vinegar and water, and then use a spray bottle or sprayer. Rinse the surface with water to remove any loose dirt and pollen left behind, as well as dust and other dirt particles. 

Step 3: Apply a Mild Fiberglass Cleaner

In addition to the care of your fiberglass frames, you should also pay attention to your window glass. To clean the glass panes of fiberglass windows, you can use a lint-free cloth or newspaper. If you use a mild cleaning solution for your fiberglass windows, you should pair it with equally gentle cleaning wiping material. If possible, use a soft microfiber cloth and use it as a base for cleaning the glass.

When cleaning fiberglass windows, remember to avoid abrasives, as they can damage the window material and ultimately cause more problems. Avoid using harsh cleaning products that contain strong chemicals on wood, fiberglass, or vinyl frames, as these can stain the surface. Certain types of cleaning solutions should be tested before you try them to avoid causing any damage, especially inside your home, where it is more noticeable. Some windows are designed to be easy to clean, making cleaning the exterior façade a breeze. However, for hard-to-reach areas of the windows, it is easier and safer to use window cleaners. Never use a high-pressure cleaner or harsh chemicals to clean part of the window; otherwise, you may permanently damage the gasket, coating, or surface. Carefully clean the fiberglass with a sponge and mild soap, or use a soft, bristly brush for hard dirt. Mix mild soap with water to wipe the frame.

Step 4: Pat Dry With Microfiber Cloth

Finally, dry your windows with a clean microfiber cloth. If you have a lot of dust in your house, a thin film of dust might build up on your fiberglass windows. Depending on the tint of your windows, the dust could be unattractive. To get rid of the dust, all you have to do is wipe your window frames with a microfiber cloth. It will suffice to eliminate the dust and restore the appearance of your window frames.

You will also need to clean your window tracks. Open the windows and run the vacuum along the tracks to remove loose dirt and debris. Once the windows are open, use a high-speed vacuum to remove the dirt and grease in the tracks. When the tracks are clean, silicone spray should be applied to ensure a clean and smooth window operation. Lubricate the tracks if necessary so that it glides smoothly, and pat dry with a dry microfiber cloth or towel. Do not spray the lubricant directly onto the track, and apply it using a towel. If there is a lot of dirt on the underside of the sash, you can temporarily remove it and use the brush tool of your vacuum cleaner and follow up with a vacuum. 

Step 5: Repeat Steps One To Four Often

Remember these steps and tips for keeping your windows sparkling clean, and repeat these steps as necessary.  There is no right or wrong way to wash your fiberglass window as long as you use a material and a cleaning solution that is safe for the window. Nevertheless, applying these methods works well for wide range glass windows, as well as for many other types of windows.

If you know the best tips for cleaning fiberglass windows, you can do this efficiently and safely. You can now clean your fiberglass windows confidently and enjoy a beautiful, clear view of nature.
