Cleaning the windows is one of those essential tasks that can sometimes be neglected, but it is critical to maintaining the aesthetic appeal of the house’s exterior and ensuring that we can get the most natural light into our homes. In this article, we will provide you with 12 simple steps on how to clean your plastic windows effectively. So, let’s get started!


Step 1: Gather the Essential Supplies

Before we get started, the first step is to gather all the necessary materials and tools. You will need a bucket, a sponge or a soft cloth, a squeegee, a cleaning solution, and water. It is best to use a specific cleaning solution made for plastic windows to ensure that you don’t damage them.

Step 2: Choose the Perfect Time to Clean Your Windows

Picking the perfect time to clean your windows plays an important role in removing dirt and grime quickly and efficiently. We recommend choosing a cloudy day, or early in the morning, or late in the afternoon when the sun isn’t shining directly on your windows. Direct sunlight can cause the cleaning solution to dry too quickly, causing streaks.

Before cleaning the actual windows, it’s essential to clean the window sills and frames first. Use a brush or a vacuum to remove all the dust and dirt.

Step 4: Apply the Cleaning Solution

Apply the cleaning solution on your sponge or soft cloth and start cleaning your windows. Make sure to apply the solution evenly and avoid using too much pressure, as this can cause scratches on the plastic surface.

Using a sponge or a soft cloth, thoroughly clean your window from top to bottom in a circular motion.

Step 6: Remove Excess Cleaning Solution Using a Squeegee

Using a squeegee, remove the excess cleaning solution from the window. Start from the top of the window, dragging it down in a straight line.

Step 7: Wipe Off Remaining Water Droplets

Use a dry cloth or a squeegee to wipe off any remaining water droplets from the window.

Step 8: Clean Hard to Reach Areas

Use a brush or a sponge to clean hard-to-reach areas such as corners or tight spaces. You can also use a cotton swab to clean small crevices.

Step 9: Repeat on the Other Side of the Window

Repeat the same process on the other side of the window.

Step 10: Clean with Plain Water

Rinse the window with plain water to remove any remaining cleaning solution.

Step 11: Dry the Window with a Dry Cloth
