Short answer: Clean acrylic with a few drops of mild dish soap in lukewarm water and a soft microfiber cloth, using light pressure, then rinse and blot dry. Rinse off dust first, because wiping dry dust scratches. Don't use Windex-type glass sprays, acetone, gasoline, lacquer thinner, full-strength alcohol, paper towels, or abrasive pads. For grease or tar, Acrylite and Optix approve hexane, aliphatic naphtha, or kerosene, washed off right after.
Key facts
- Best everyday cleaner: mild soap or dish detergent in lukewarm water, a soft cloth, light pressure. Acrylite (Röhm), Optix (Plaskolite), and Plexiglas (Röhm/Polyvantis) all give this as the first choice.
- Never clean it dry. The Plexiglas cleaning guide warns that wiping a dry, dusty surface scratches it.
- Grease, oil, tar, sticky residue: hexane, aliphatic naphtha, or kerosene (Acrylite, Optix), then wash with soap and water.
- Don't use: acetone, gasoline, benzene, lacquer thinner, carbon tetrachloride, window-cleaning sprays, scouring powders. Acrylite says these can scratch the sheet or cause crazing.
- Disinfecting: Acrylite approves isopropyl alcohol diluted to 30%, 3% hydrogen peroxide, or bleach at 5 tablespoons (1/3 cup) per gallon of water.
- Plastic cleaners that say they're for acrylic (Novus No. 1, Brillianize, Plexus) are fine for touch-ups and add an anti-static finish.
The safe way to clean acrylic, step by step
Acrylic is a hard plastic, but it's much softer than glass. Most damage happens when grit gets dragged across the surface or when a cleaner attacks the plastic chemically. This method avoids both.
- Get the dust off without wiping. Dry dust is fine grit. Rinse it off with water, blow it off with low-pressure air, or lay a damp microfiber flat and lift it. Don't rub a dry cloth across a dusty panel.
- Mix a mild wash. A few drops of plain dish soap in a bucket or spray bottle of lukewarm water. Hot water isn't needed, and water near acrylic's 160 to 180 °F (70 to 80 °C) service limit can warp thin sheet.
- Wash with a soft, clean microfiber cloth. Light pressure and plenty of water, so any grit floats away instead of being dragged. Rinse the cloth often.
- Rinse with clean water to remove soap film, which streaks and attracts dust.
- Blot dry. Acrylite's instructions say to blot with a damp cloth or chamois rather than rub. Hard rubbing builds static.
Tip: Keep one microfiber cloth just for acrylic. Brillianize, a maker of acrylic cleaner, recommends washing microfiber with liquid soap and no fabric softener. A cloth that picked up grit from a countertop or car will scratch.
What should you never use on acrylic?
| Avoid | Why |
|---|---|
| Windex and other window-cleaning sprays | Acrylite lists window-cleaning sprays as a do-not-use. Their solvents can haze the surface and cause crazing, a web of fine cracks, especially at holes and cut edges. |
| Full-strength rubbing alcohol, denatured alcohol, hand sanitizer | Optix's guide says denatured alcohol softens the surface and often causes crazing. Laser-cut and bent parts hold stress and craze first. |
| Acetone, lacquer thinner, MEK, gasoline, benzene | These soften or dissolve acrylic. Acetone fogs it almost instantly. |
| Paper towels and tissues | Wood fiber leaves fine hairline swirls on acrylic. |
| Scouring pads, Magic Eraser, abrasive powders | All abrasive. A melamine sponge works by sanding. |
| Razor blades, scrapers, squeegees | Optix warns these can permanently scratch the sheet. |
Not sure about a cleaner? Test it on a hidden corner or an offcut and leave it for a day. Crazing can show up hours later. What crazing is and why it happens.
Is ammonia or alcohol always off-limits?
Not quite, and the makers don't fully agree. Acrylite's general cleaning list says no alcohol, but its disinfecting guide approves isopropyl alcohol diluted to 30%. Plaskolite allows a water and isopropyl mix of 30% maximum with short contact time, and one Optix fabrication guide says household ammonia diluted to normal cleaning strength is fine. The Plexiglas guide rules out ethanol and other alcohols in cleaners but allows isopropanol for disinfecting.
What they agree on: strong solvents and full-strength alcohol are the risk, and stressed areas craze first. That's why we tell people to skip Windex and alcohol wipes. Soap and water does the job and never crazes anything.
Are acrylic cleaners like Novus and Brillianize worth it?
Yes, for fingerprints and quick touch-ups, and they leave the panel cleaner for longer. What the makers say:
- Novus No. 1 Clean & Shine has no abrasives. Novus says it resists fogging and fingerprints, repels dust, and eliminates static. (Novus No. 2 and No. 3 are scratch removers, not cleaners.)
- Brillianize is a spray cleaner and polish the maker says is formulated for plastics including acrylic, Plexiglas, and Lucite. Its tips page says it leaves an anti-static finish. Spray, wipe a couple of square feet at a time, and buff all the liquid off.
- Plexus is an aerosol cleaner and protectant, also from the aviation world. The maker says it leaves a micro-thin wax layer with anti-static properties.
None of these replace washing a dusty or gritty panel. Spray-and-wipe on dust still drags dust. Rinse first, then use the cleaner.
How do you clean and sanitize acrylic sneeze guards?
Sneeze guards, desk dividers, and counter shields get cleaned many times a day, so they're where most cleaning damage happens.
- Clean first, then sanitize. Soap and water removes grime, and disinfectants work poorly on a dirty surface.
- Use a maker-approved disinfectant. Acrylite lists 3% hydrogen peroxide, isopropyl alcohol diluted to 30%, Lysol Brand with Hydrogen Peroxide Multi-Purpose Cleaner, bleach at 5 tablespoons per gallon (4 teaspoons per quart), Clorox Healthcare Bleach Germicidal Disinfectants, and OPTIM 1 or OPTIM 33 TB.
- Avoid the wipes Acrylite tested as not compatible: PDI Sani-Cloth HB and AF3, Clorox Hydrogen Peroxide Cleaner/Disinfectant Wipes, Fantastik All-Purpose Cleaner, and Microban 24 Hour Bathroom Cleaner.
- Wipe with clean water after the contact time. Residue dried on over and over builds into haze and crazing.
- Watch the edges and holes. Laser-cut edges and drilled holes hold the most stress.
If your required product isn't on an approved list, test it on a small area, or ask its maker about acrylic. For new guards, see acrylic sneeze guards. Flame-polished or machined edges hold less stress than laser-cut ones if harsh cleaning can't be avoided.
How do you keep acrylic from attracting dust after cleaning?
Rubbing acrylic charges it with static, and charged plastic pulls dust from the air. Blot instead of rubbing, finish with an anti-static plastic cleaner, and keep room humidity reasonable. Details in how to stop acrylic static and dust.
What about scratches that are already there?
Cleaning won't remove scratches, but fine ones polish out with Novus No. 2 or a similar plastic polish, and deeper ones can be wet sanded and buffed on uncoated sheet. See how to remove scratches from acrylic. If a panel is too far gone, we can cut a replacement to the same size: enter the dimensions in the instant quote to see your price.
Questions
Can I clean acrylic with vinegar?
Yes. Plaskolite lists vinegar as its preferred wipe for masking residue and suggests it for labels and stickers, rinsed off with lukewarm water. Diluted white vinegar also helps with hard-water spots. Soap and water is still the best everyday cleaner.
Can I use Clorox or Lysol wipes on acrylic?
Check the exact product. Acrylite tested Clorox Hydrogen Peroxide Cleaner/Disinfectant Wipes as not compatible, but approves Lysol Brand with Hydrogen Peroxide Multi-Purpose Cleaner and a diluted bleach solution. Wipe with clean water afterward.
Why does my acrylic look cloudy after cleaning?
Usually it's soap film or cleaner residue: rinse with clean water and blot dry. If the haze doesn't wash off, it's fine scratching from dry wiping or paper towels (polish it out) or crazing from a solvent (permanent).
Should I clean acrylic before removing the protective film?
No need. The film keeps the surface clean until installation. Peel it, then clean once if needed. If it's baked on, see how to remove stuck protective film.
Can I hose down outdoor acrylic?
Yes, a garden hose is a great way to rinse off dust before washing. Avoid a pressure washer at close range, which can drive grit into the surface and stress edges and seals.
