Glass Cleaner is a cleaning solution formulated to safely clean glazing materials used in picture framing, including both glass and acrylic. For artwork protection, only ammonia-free cleaners should be used, as ammonia can damage coatings, degrade UV-protective layers, and cause long-term harm to frames and art.

Functions of Glass Cleaner in Framing

Dust and smudge removal: eliminates fingerprints, dust, and surface residues from glazing.
Streak-free clarity: maintains clear visibility of the artwork.
Preservation of coatings: ammonia-free solutions protect UV-filtering and anti-reflective coatings from deterioration.
Safe for acrylic: certain cleaners are formulated to prevent streaking or hazing on acrylic surfaces, which are more sensitive than glass.

Types of Glass Cleaners

Ammonia-Free Glass Cleaner: designed specifically for use with conservation glass, museum glass, and acrylic glazing.
Acrylic-Safe Cleaners: specialized formulations that prevent scratching and static buildup on acrylic sheets.
General Household Glass Cleaner: often contains ammonia and should be avoided for framing use, as it can damage protective coatings and materials.

Considerations When Using Glass Cleaner

Avoid spraying cleaner directly on the glazing while framed artwork is present; instead, spray onto a microfiber cloth to prevent seepage into mats or artwork.
Always use a lint-free microfiber cloth or cotton cloth-paper towels can scratch acrylic or leave fibers.
Check manufacturer recommendations for cleaning museum-grade or anti-reflective glass, as some require specific solutions.
Do not use abrasive pads, as they can scratch coatings or acrylic surfaces.

Best Practices

Choose ammonia-free cleaners labeled safe for both glass and acrylic.
Spray the cloth, not the glazing, to avoid liquid wicking into the frame.
Use gentle circular motions to reduce streaks and prevent scratching.
Store cleaners in a climate-controlled space to preserve their chemical stability.

FAQs

Can I use Windex� or similar household cleaners on framing glass?: Most household glass cleaners contain ammonia, which can damage coatings and should not be used. Only ammonia-free versions are safe for conservation glass or acrylic.
What is the best way to clean acrylic glazing?: Use an acrylic-safe, ammonia-free cleaner with a microfiber cloth. Avoid paper towels, as they can scratch the softer acrylic surface.
How often should I clean glazing?: Clean only as needed-frequent unnecessary cleaning increases the risk of scratches or abrasion.
