Andersen Windows is one of the most widely installed premium window brands in Southwest Florida. Their products range from standard double-hung to large architectural casements, and most modern Andersen windows include Low-E glass coatings and weatherstripping that require specific care. Here’s what you need to know for cleaning them properly in Naples.

Andersen’s Official Cleaning Guidelines

Andersen recommends using mild soap and water with a soft cloth for glass cleaning. They specifically advise against abrasive cleaners, steel wool, and ammonia-based products on their Low-E coated glass. For frames (Fibrex composite or vinyl), they recommend mild household cleaners and explicitly warn against solvents, petroleum-based cleaners, and power washing.

What Naples Conditions Add

Andersen’s standard guidelines don’t account for the salt air and mineral water conditions in Naples. Two additions are necessary for this environment:

• Purified rinse water — Naples tap water deposits minerals on Andersen’s Low-E glass as it dries. Always finish with purified or distilled water to prevent spotting.
• Mineral treatment when needed — calcium and silica deposits from irrigation overspray require diluted acid treatment. Use a product safe for Low-E glass — not all mineral removers are — and test on a small inconspicuous area first.

Fibrex Frame Care in Naples

Andersen’s Fibrex composite frames hold up well to Naples’ humidity but do accumulate mildew in the grooves and weep hole areas. Clean frame surfaces with mild soap and a soft brush annually. Check that weep holes — small drainage slots at the bottom of frame channels — are clear. Blocked weep holes allow water to pool and accelerate mold growth at the frame-glass junction.
