How To Clean A Composite Door

Composite doors are an excellent choice for homeowners who are looking for a low maintenance and durable option for their entryway. Although composite doors are designed to withstand harsh weather conditions and daily wear and tear, they still require cleaning to maintain their appearance and functionality. A bucket of warm soapy water and a soft clean cloth is all you need to clean your composite doors.

In this article, we'll outline the steps you need to follow when cleaning a composite door.

What Materials are Needed to Clean Composite Door?

You will require the following materials to clean a composite door-

  • Soft-bristled brush
  • Mild soap or detergent
  • Warm water
  • Microfiber cloth
  • Bucket
  • Garden hose or pressure washer

Steps for Cleaning a Composite Door 

Follow the below-mentioned steps to clean a composite door yourself.

Step 1: Preparing the door 

Before you begin cleaning the composite door, you need to prepare it properly. Inspect the door for any signs of damage, such as cracks, scratches, or dents. If you find any damage, consider contacting a professional to repair it before cleaning the door.

Step 2: Removing Dirt and Debris  

Start by removing any loose debris or cobwebs that may have accumulated on or around the door's frame. You can do this with the help of a soft-bristled brush. Focus more on the corners of the door frame as they are more prone to dirt and debris.

Step 3: Clean Composite Door (Glass & Furniture)

To clean the composite door, start by moistening the door's surface with water using a hose or a bucket of water. Next, mix a small amount of soap or detergent with warm water, in a bucket and use a soft-bristled brush to apply the soapy water solution to the door's surface.

Scrub the door gently with the brush, paying extra attention to areas where dirt and grime may have accumulated, such as around the handle or the edges of the door. Avoid rigorous cleaning, as this can damage the door's surface.

Once you've scrubbed the door thoroughly, rinse it off with water to remove any soap residue. Use a microfiber cloth to dry the door's surface, making sure to remove any remaining water or soap residue.

Step 4: Maintaining the Door

Regular cleaning is essential to maintaining the appearance and functionality of your composite door. To keep your door looking great, clean it with a soft sponge or a dry cloth, at least once every six months or more frequently if it is exposed to harsh weather conditions or heavy use. In addition to regular cleaning, consider applying a protective coating or wax to the door's surface to provide extra protection against dirt, moisture, and UV rays.

Tips for Maintaining a Clean Composite Door

You can easily maintain your clean composite door by following the below-mentioned tips- 

  • Avoid Abrasive Cleaning Tools

It's important to avoid using abrasive cleaning tools such as steel wool, scouring pads, or rough brushes on your composite door. These tools can scratch or damage the surface of the door, which can lead to discoloration or even structural damage over time.
  • Clean Regularly

Regular cleaning is essential to keep your composite door in good condition. Use a soft cloth and mild soap or detergent to clean the door.
  • Avoid Harsh Chemicals

Avoid using harsh chemicals like bleach, ammonia, or solvent-based cleaners on your composite door as they can damage the door's surface or cause discoloration. If you need to remove a stubborn stain or mark from your composite door, use a specialized composite cleaner that is formulated to be gentle on the surface of the door.
  • Wipe up Spills Immediately

If you notice any stains, loose dirt or marks or spills on your composite door, it's important to remove them as quickly as possible. Use a mild soap and water solution or a specialized composite door furniture cleaner to remove the stain.

FAQs on How To Clean A Composite Door

  • Does WD 40 clean composite doors?

WD-40 is not recommended for cleaning composite doors as it is primarily a lubricant and water displacement spray, rather than a cleaning agent. It's best to use a mild detergent solution or soap and water to clean composite doors, avoiding abrasive cleaning products that may damage the surface.
  • Do all composite doors fade?

Most composite doors are designed to be resistant to fading, but exposure to sunlight and weather conditions can cause some degree of fading over time. However, high-quality composite doors are usually manufactured with UV-resistant technology and durable finishes that help to minimize fading, ensuring long-lasting beauty and optimal performance throughout.
  • How do you restore color in composite doors? 

To restore color in composite doors, you can use specialized composite door restoration kits that are designed to remove scratches and restore the original color and shine. Alternatively, you can use a high-quality exterior paint or stain that is specifically formulated for use on composite materials to restore color and protect against fading, weathering, and other damage.
  • What is the life expectancy of a composite door? 

The life expectancy of a composite door varies depending on several factors, such as the quality of materials, installation, and maintenance. However, high-quality composite doors can last up to 35 years or more with minimal maintenance and proper care, making them a long-lasting and cost-effective investment for homeowners.
