Cleaning Andersen Windows in Michigan: The Right Approach

Andersen Windows in Michigan Homes

Andersen is the most widely installed premium window brand in Michigan. Walk through any established neighborhood in Birmingham, Bloomfield Hills, or Beverly Hills and you'll find Andersen windows in a significant share of the homes — from the 400 Series in mid-range renovations to the E-Series and A-Series in high-end custom builds. Andersen has maintained that market position through consistent quality and a strong warranty program, but that warranty has specific terms, and improper cleaning is one of the ways homeowners inadvertently void it.

What Makes Andersen Windows Different

Fibrex Composite Frames

Andersen's most distinctive material innovation is Fibrex composite, a proprietary blend of reclaimed wood fiber and thermoplastic polymer. Used in their 100 Series and 200 Series products, Fibrex is designed to be more dimensionally stable than vinyl (it expands and contracts less with temperature change) and more rot-resistant than wood.

But Fibrex has specific cleaning requirements. It is not impervious to chemical attack — harsh solvents, solvent-based paint removers, and abrasive cleaners can dull the surface, create micro-pitting, and in some cases cause localized discoloration that cannot be reversed. Andersen explicitly states in its care and maintenance guides that abrasive cleaners should never be used on Fibrex surfaces.

Wood Interior Surfaces

Many Andersen window lines — including the E-Series and A-Series — feature wood interior surfaces, either factory-primed for painting or factory-finished in standard colors. Wood interiors are the most moisture-sensitive component of any window, and cleaning technique that allows water to pool at the sill-glass junction, run down the interior stop bead, or saturate the bottom rail will cause swelling, paint failure, and in severe cases, rot at the wood-composite joint.

This is not a theoretical risk — it is among the most common window damage ClearView encounters during cleaning assessments. Interior windowsill paint failures and bottom rail swelling are frequently the result of DIY cleaning with too much water and no attention to drainage.

High-Performance Glass Packages

Andersen's higher-end lines use glass packages with low-E coatings, heat-mirror glazing systems, and in some cases triple-pane configurations. All of the low-E coating precautions described in a separate post on this site apply fully to Andersen glass: no razor blades, no ammonia-based cleaners, no abrasive pads.

What Andersen Recommends for Cleaning

Andersen's published care guidelines recommend cleaning glass with a mild, non-abrasive glass cleaner and a soft cloth or sponge. For frames, they recommend a mild soap-and-water solution and rinse thoroughly — never allowing cleaning solution to dry on the frame surface. They specifically caution against:

• Abrasive cleansers or scrubbing pads on any surface
• Petroleum-based solvents, paint thinners, or nail polish remover near frames
• Pressure washing that directs high-pressure spray at seals, glazing compound, or weather stripping
• Razor blades on glass surfaces (they void the glass warranty)

Professional window cleaners follow these same guidelines, but with the additional benefit of equipment — pure water systems, professional squeegees, and technique that eliminates the streaking and residue that most homeowner attempts leave behind.

ClearView's Andersen-Safe Protocol

ClearView Exterior Services has cleaned Andersen windows throughout Oakland County for years and has developed a specific protocol aligned with Andersen's care requirements:

• Fibrex-safe cleaning solutions only — no solvents, no abrasives, no petroleum-based products near composite or wood frame surfaces.
• Controlled water application — water is not allowed to pool at frame joints, sill junctions, or bottom rails. Interior cleaning includes immediate wipe-down of any moisture at wood surfaces.
• No razor blades on Andersen glass — hard deposits are addressed with appropriate non-blade techniques.
• Low-E safe glass cleaning — ammonia-free solutions and no abrasive applicators on any Andersen glass surface.
• Hardware and operator care — Andersen's folding hardware, operators, and locking mechanisms are kept dry and free of cleaning product residue.

Protecting Your Andersen Warranty

Andersen's warranty covers manufacturing defects, but physical damage caused by improper maintenance — including cleaning-related damage to glass, frames, or seals — is typically not covered. Maintaining a professional cleaning record with a company that follows manufacturer-approved methods is the best documentation you can have if a warranty question ever arises.
