Owner's Manual

Cleaning & Maintenance

Purchasing windows is not unlike buying other building products. When a question arises, a helpful guide can lead you through common questions such as finishing interiors/exteriors, adjusting a hardware system or cleaning glass.

Our owner’s manual is a user-friendly guide intended to provide information and recommendations related to Timeline Windows and Patio doors. Products tend to look better and last longer with the proper care and maintenance.


Glass Cleaning

Routine Cleaning

Clean the glass as soon as dirt and or debris become apparent. Products such as Windex® and Sparkle® work well for routine hand cleaning. A mixture of one part vinegar with ten parts water is also an excellent cleaning product. Lincoln does not recommend alcohol-based or ammonia-based cleaners as they tend to leave visible streaks.

Start cleaning at the top of a particular wall or window and work your way down. Apply the liquid liberally to the glass surface and wipe with a lint free towel or cloth. Use a squeegee or clean soft cloth with clean water, to remove the cleaning solution from the glass as well as the frame and surrounding materials. To prevent streaking, stop wiping when the glass is almost dry and there is still a uniform film of moisture on the glass. This film will quickly evaporate leaving a clean surface. NOTE: Do not wipe with a dry cloth or when the surface is dry.

Spot Cleaning

For stubborn dirt or foreign materials, such as grease, oil, tape adhesive, paint and even crayons, standard glass cleaner may not suffice. For these instances, products such as Soft Scrub®, Denatured Alcohol, Acetone or Goof-Off® should be used.

Apply a small quantity of the liquid to a clean WET cloth. Rub on the surface requiring spot cleaning. Wipe clean and follow up with the routine cleaning procedure given above. NOTE: Do not wipe with a dry cloth or when the surface is dry.


Dual Low-E Glass Cleaning

The interior of the surface of the Dual Low-E Glass has a thin pyrolytic coating which gives it an improved thermal performance. The low emissivity coating has a very fine, hard texture which requires a slightly different cleaning procedure when compared to regular glass.

Routine Cleaning and Spot Cleaning

Follow the Glass Cleaning procedures above with one exception - Never use a squeegee on the low emissivity surface.

Specialized Cleaning

While metallic objects, such as razor blades or steel wool should never be used to clean glass surfaces, it is especially important when working with Dual Low-E glass. The low-emissivity surface on the interior of the glass is actually harder than the metallic objects and a thin layer of the metal may be removed from the object and deposited on the surface of the glass which may appear as a ‘stain’ or ‘scratch’. These cannot be removed by routine cleaning. For the removal of metal marks, you will need to use products such as Acid Magic®, Steel Glo® or Muriatic Acid.

Apply a small quantity of the liquid to a clean wet cloth and rub on the glass surface until the mark is removed. Wipe clean and follow up with the routine cleaning procedure to remove any residue left by the specialized cleaning liquids. NOTE: Do not wipe with a dry cloth or when the surface is dry. NOTE: Never spray products such as Acid Magic®, Steel Glo® or Muriatic Acid directly on the glass surface. The over-spray of these liquids may damage non-glass window components such as wood, vinyl or silicone.


Neat® & Preserve®

Follow the Glass Cleaning procedures for Neat® glass. Neat® glass products should require less maintenance on the exterior.

Lincoln recommends removing Preserve® films within six months of installation. Follow the Glass Cleaning procedures if glass cleaning is required.


Precautions & Warnings

  • Do not use power washers or garden hoses to clean windows.
  • Do not use metal scrapers of any kind or allow metal parts of cleaning equipment to contact glass. The Lincoln warranties do not cover glass scratched by scrapers, razor blades, or tools.
  • Do not use abrasive cleaners on the glass surface.
  • Do not clean windows in direct sunlight.
  • Do not allow cleaning solutions to dry on glass or surrounding surfaces.
  • Windows and doors should be protected when using abrasive or caustic cleaners on products around windows. Brick wash acids, abrasive cleansers and the like can all damage the surfaces of glass as well as the finish of vinyl and metal parts.

Screen Cleaning

To clean your screen of dust and light debris you may use the upholstery brush supplied with your vacuum cleaner. Heavier debris such as kitchen grease may be removed by gently scrubbing with mild soap and a soft brush. Screens should be rinsed to remove dirt and soap residue. Be sure that screens are dry before they are re-installed.
