Clean acrylic picture frame glazing with a soft microfiber cloth and plain water or a mild dish soap solution, never ammonia or paper towels.
Acrylic scratches and clouds far more easily than glass, so the way you clean it matters. One wrong wipe with a paper towel or a spray of Windex can leave permanent damage. Routine maintenance takes seconds, and a deeper clean only needs a few household items. Here’s the exact method that keeps acrylic looking clear without harming the frame or artwork.
Why Acrylic Needs Different Care Than Glass
Standard glass cleaners contain ammonia, the fastest way to ruin acrylic—it attacks the surface, leaving a cloudy haze that won’t wipe off. Abrasive materials like paper towels, rough tissues, and scouring pads scratch the soft surface, and those scratches catch light as dull streaks.
Acrylic is a plastic, not glass, so glass rules don’t transfer. The material is lighter and more shatter-resistant, which is why so many frames use it, but that durability comes with a softer surface demanding gentler tools. The single most important rule: if a product says it’s for glass, check the label for ammonia before it touches acrylic.
What You Should (And Shouldn’t) Use On Acrylic
The safe list is short. A fresh microfiber cloth, distilled water, and a drop of mild dish soap cover nearly every job. For stubborn grime, isopropyl or denatured alcohol works on standard acrylic, and acrylic-specific products like Novus No. 1 Plastic Clean & Shine are safe on normal surfaces.
- Safe: microfiber cloths, lint-free cotton, distilled water, mild dish soap, isopropyl alcohol, acrylic-specific polishers.
- Unsafe: Windex (on standard acrylic), ammonia cleaners, paper towels, abrasive pads, acetone, furniture polish, harsh scrubbing.
One exception: That approval applies to those specific Plexiglas grades, not every acrylic frame. Unless your frame’s manufacturer confirms compatibility, stick with water and soap.
The Step-By-Step Cleaning Method
How you apply the cleaner matters as much as what you use. Spraying liquid directly onto the frame lets moisture seep into the edges and damage the artwork or backing board. Always apply to the cloth first.
Start by dry-dusting the acrylic with a clean microfiber cloth—this handles most maintenance. For fingerprints or grime, dampen a fresh cloth with distilled water and a single drop of mild dish soap. Wipe with light pressure using straight lines or gentle circles, then rinse the cloth, go over the surface again with plain water to remove soap residue, and blot dry with a separate clean cloth. Leaving water to air-dry leaves spots, so the final dry pass is non-negotiable.
If the surface still looks streaked, test a small amount of isopropyl alcohol on an inconspicuous corner before using it across the whole frame. Apply it to the cloth, not the acrylic, and buff dry immediately. For coated acrylic like Optium Museum glazing, the rules tighten further: never use polishers like Novus on it, because they can destroy the anti-reflective coating entirely.
How To Prevent Damage Before It Starts
Most acrylic damage happens during cleaning, not from everyday handling. The most common mistakes are reaching for paper towels out of habit and using glass cleaner without checking the label. Both are easy to avoid once you know the risk.
When you first get a new acrylic frame, wipe the edges with a damp cloth before removing the protective cover—this reduces static charge that pulls dust onto the surface. After that, a quick dry dusting once a week with microfiber keeps the frame clear. Rethink every cleaning product you keep near your frames: if it contains ammonia, acetone, or any abrasive ingredient, it belongs nowhere near acrylic.

| Cleaning Task | What To Use | What To Avoid |
|---|---|---|
| Routine dusting | Dry microfiber cloth | Paper towels, feather dusters |
| Fingerprints or grime | Distilled water + mild dish soap, cloth-applied | Spraying directly on frame, abrasive pads |
| Stubborn residue | Isopropyl alcohol or Novus No. 1 | Windex, ammonia, acetone |
| Coated acrylic (Optium) | Water only, soft cloth | Novus polishers, any abrasive cleaner |
Acrylic care comes down to three habits: dry-dust first, apply liquid to the cloth not the frame, and never grab a paper towel or ammonia spray. Follow those, and your acrylic frame stays crystal clear for years. The moment you notice haze or scratches, stop and reassess your cleaning products—the damage is almost always chemical or abrasive, not from normal wear.
FAQs
Can I use regular glass cleaner on acrylic frames?
Only if the label confirms it’s ammonia-free. Most standard glass cleaners like Windex contain ammonia, which clouds and dulls acrylic surfaces permanently. Check the ingredient list before use, and when in doubt, plain water and a microfiber cloth are always safe.
Why does my acrylic frame look hazy after cleaning?
Haze usually means the cleaner contained ammonia or the cloth was too abrasive. The surface has likely micro-scratched or chemically clouded, and that damage is generally not reversible. Switching to a microfiber cloth and ammonia-free products prevents the problem from worsening.
Is it safe to spray water directly on the acrylic frame?
No. Spraying liquid directly onto the frame lets moisture creep into the edges and damage the artwork or backing board inside. Always dampen your cloth first, then wipe the surface. This simple habit extends the life of both the frame and the piece it protects.
