Caring for Your Krosswood Fiberglass Door

While fiberglass doors are weather-resistant, long-lasting, and low maintenance, it’s important to maintain the appearance and function of your door. Not only will this keep your door looking brand new, but it will prolong the longevity of a fiberglass door to last for generations to come.

Cleaning is one of the best ways to keep your fiberglass door functioning exceptionally. Without regular cleaning, dirt and dust can build up over time and will be very difficult to remove. This can eventually affect the performance of your fiberglass door.


Routine Cleaning 

Frequency: Clean your door 1-2 times per year to prevent dirt buildup. Aim to clean more often in areas with high dust or pollution.

Materials: Use a soft, damp cloth or sponge to wipe down every flat surface of your fiberglass door. Mild soap and water are usually sufficient. Avoid abrasive cleaners, chemicals, or scouring pads as they can damage the surface and/or stain of your door.

Glass Cleaning: For the glass inserts, use a glass cleaner specifically designed for windows or glass surfaces. Avoid getting the cleaner on the fiberglass frame. 

Do not power wash your door, as it can wear down and damage the wood-like fiberglass surface.


Inspect Regularly: Periodically inspect the door for signs of wear, damage, or deterioration. Pay attention to hinges, locks, and weather stripping. A crooked door is like one bad tire, which can mess up the alignment and damage the rest of your door over time.

Lubrication: Lubricate hinges and locks as needed with a silicone-based lubricant, such as WD-40, to prevent squeaking or sticking.

Weatherstripping: Ensure weather stripping and threshold are intact and properly sealed to prevent drafts and moisture infiltration. Replace the threshold and weather stripping as needed, to ensure your door stays dent and moisture free.

Repairs: Address any damage promptly. Consult a professional for any significant repairs or replacements.

Glass Care

Cleaning: Clean the glass regularly as part of your routine maintenance. Use a glass cleaner and a lint-free cloth to remove smudges, fingerprints, and dirt.

Avoid Scratches: Never use abrasive materials or harsh chemicals on the glass as they can scratch or damage the surface.

Condensation: If condensation forms on the glass during extreme weather, wipe it away to prevent moisture-related issues.
