Enclosure Cleaning & Care Guide
Mild dish soap, lukewarm water and a microfiber cloth clean every panel on a Clearview enclosure. The products that do the damage are the ones people reach for out of habit: glass cleaner, rubbing alcohol, acetone and paper towels.
Know your panels
Clearview enclosures use four sheet materials. If you are not sure which material a panel is, ask us, or clean it as acrylic: acrylic is the most sensitive of the four, so the acrylic rules are safe on every panel.
| Material | Typical use | How to tell | Weak spot |
|---|---|---|---|
| Acrylic (PMMA, Plexiglas, Optix, Acrylite) | Clear and tinted panels, doors, hatches, laser-filtering windows | Rigid. Rings when tapped. Flexes very little before it cracks. Laser-cut edges are glossy and clear. | Cut edges and screw holes craze (fine cracks) when alcohol or solvent reaches them |
| Polycarbonate (PC, Lexan, Makrolon, Tuffak) | Impact-rated panels, some laser viewing windows | Bends noticeably without cracking. Duller sound when tapped. Laser-cut edges look brownish. | Ammonia and alkaline cleaners attack the plastic itself, not just the surface |
| PVC (solid or foam, Sintra, Komatex) | Opaque white, black or grey panels and bases | Opaque, satin finish. Foam PVC is light for its thickness and shows fine cells at the cut edge. | Acetone, MEK and PVC cement dissolve it. Hard rubbing changes the sheen. |
| ACM (aluminum composite, Dibond, Alucobond) | Rigid opaque panels with a painted metal face | Cold to the touch. The cut edge shows two thin aluminum skins over a plastic core. | The paint. Abrasives cut through it; acetone dulls it. |
Laser viewing windows follow the strictest rules in this guide whatever they are made of: the acrylic never-use list, plus no polishing, sanding or scraping (see Machine-specific messes).
The routine: safe on every panel
This wash is approved by the acrylic, polycarbonate, PVC and ACM sheet manufacturers alike. Use it for all routine cleaning.
What you need
- Two clean microfiber cloths: one for washing, one for drying. Launder them without fabric softener, which leaves a streaky film.
- A spray bottle of lukewarm water with a few drops of mild dish soap (Dawn, Joy, Palmolive): about 1/2 teaspoon per quart (2–3 ml per liter).
- A soft, non-scratch sponge for heavier grime.
- Optional: a plastic cleaner and anti-static spray made for acrylic and polycarbonate (Brillianize, Novus No. 1).
The five steps
- Cool. Power down the machine and let the chamber cool to room temperature. Heat makes every cleaner more aggressive. Never clean a hot panel or one in direct sun.
- Dust. Lift loose dust with a damp cloth. Never wipe dry: dry dust is grit, and dragging it scratches the surface and charges it with static that pulls in more dust.
- Wash. Spray the cloth, not the enclosure, so liquid stays out of cut edges, screw holes and your machine. Wipe in straight strokes with light pressure.
- Rinse. Wipe again with a cloth dampened in clean water. No cleaner should be left to sit on a panel.
- Dry. Blot with the dry cloth. For less dust, mist on anti-static cleaner and wipe lightly without rubbing it dry.
How often
| Machine | Inside the enclosure | Outside |
|---|---|---|
| FDM 3D printer | Monthly, or when dust shows | Monthly |
| Resin 3D printer | Drips and splashes the same day; full wash monthly | Monthly |
| Laser engraver (diode, CO2, galvo, fiber) | Inspect the viewing window before every job; full wash weekly with daily use | Monthly |
| UV printer | Wipe ink mist weekly | Monthly |
Clean messes while they are fresh. Fresh residue comes off with soap and water. Baked-on residue is what tempts people toward solvents, and solvents are where the damage happens.
Product map: what is safe on which material
Sprays drift and cloths travel from panel to panel, so the last column is the one to follow: a product belongs on your enclosure only if it is safe on every panel in it.

A product's name is not its formula. Makers change formulas without notice, so read the label: "ammonia," "ammonium hydroxide," "alcohol," "quaternary ammonium" and "sodium hydroxide" on the ingredient list rule a product out for clear panels.
Acrylic
Acrylic is the clearest panel on your enclosure and the most sensitive to chemicals. Soap and water is all it needs.
Routine cleaning: the five-step routine. Brillianize or Novus No. 1 add shine and an anti-static layer.
Grease, oil, tar or label adhesive: a little VM&P naphtha, hexane or kerosene on a soft cloth, on the flat face only. Keep it off cut edges, screw holes and the area around binding posts. Wash with soap and water right after.
Disinfecting: 3% hydrogen peroxide, or isopropyl alcohol diluted to 30%, or household bleach at 5 tablespoons per gallon of water (4 teaspoons per quart). Wipe on with light pressure, then rinse. Not pharmacy-grade ethyl alcohol, and not ready-made disinfecting wipes: Acrylite lists PDI Sani-Cloth and Clorox Hydrogen Peroxide wipes as incompatible.
Fine scratches: a plastic scratch remover (Novus No. 2, then No. 3 for heavier marks) on a soft flannel pad, then clean and polish. Deeper scratches can be wet-sanded with 400-grit and buffed back to gloss, but that is shop work: contact us first. Never polish a laser viewing window.
Never use on acrylic
- Glass cleaner with ammonia (Windex Original), Formula 409, Fantastic
- Alcohol at full strength: rubbing alcohol, 91–99% IPA, denatured alcohol, ethanol, hand sanitizer
- Acetone, nail polish remover, MEK, lacquer thinner, gasoline, benzene, carbon tetrachloride
- Highly alkaline cleaners and degreasers
- Paper towels, Magic Erasers, scouring pads, razor scrapers
Why acrylic crazes. Crazing is environmental stress cracking: a network of fine cracks that grows where a solvent meets plastic already under tension. Laser and CNC cutting lock tension into every cut edge and hole, and a tightened binding post adds more. Alcohol or solvent that reaches those spots opens cracks that can appear hours or days after cleaning and cannot be wiped away. Acrylite's fabrication guidance names joints, cuts and drilled holes as where crazing starts. That is why the routine sprays the cloth, never the panel, and why a cleaner that seems fine on the flat face can still crack a panel at its screw holes.
Polycarbonate
Polycarbonate takes impacts that would crack acrylic, but it is softer, scratches more easily and is attacked chemically by ammonia and alkaline cleaners.
Routine cleaning: the five-step routine. Tuffak lists Joy, Palmolive Liquid, Top Job and Windex Ammonia-Free as compatible.
Grease, oil or tar: rub gently with a 50/50 mix of isopropyl alcohol and water on a soft cloth. Rinse with lukewarm water right away and dry.
Paint, marker, ink or cured UV ink: a soft cloth dampened with VM&P naphtha or isopropyl alcohol. Rinse right away. Never in direct sun or on a warm panel.
Label adhesive: isopropyl alcohol, VM&P naphtha or kerosene loosens it. Rinse and dry afterward.
Disinfecting: 3–5% hydrogen peroxide, or 70% isopropyl alcohol. Not bleach at any dilution, and not quaternary-ammonium disinfectants: Plaskolite tested Lysol disinfectant spray, Clorox broad-spectrum quaternary cleaner, PDI Super Sani-Cloth and Zep products as not compatible with Tuffak.
Scratches: leave them. Polycarbonate does not polish back the way acrylic does, and a hard-coated sheet loses its coating to any polish. Deep gouges mean a replacement panel: contact us.
Never use on polycarbonate
- Anything with ammonia: Windex Original, Formula 409
- High-pH cleaners: degreasers, oven cleaner, caustic soda
- Bleach, at any dilution
- Acetone, MEK and other ketones; toluene, xylene, benzene; methylene chloride and other chlorinated solvents; gasoline
- Abrasive cleaners, paper towels, squeegees, razors, scrapers
Never let any cleaner sit or pool, and keep it off the cut edges, which have no protective coating.
Why polycarbonate cracks. Polycarbonate is a chain held together by carbonate links. Ammonia and amines break those links directly (Covestro describes trans-amination damage), and alkaline solutions do the same through hydrolysis. Ketones, aromatic and chlorinated solvents swell the surface and set off stress cracking wherever the sheet is under tension: cut edges, holes, bent or clamped areas. Palram's chemical resistance data rates acetone, ammonia gas and aqueous ammonia as not resistant.
PVC
PVC is the most forgiving panel toward alcohol and the least forgiving toward acetone. It is the one panel where isopropyl alcohol is a normal cleaner.
Routine cleaning: a soft cotton or microfiber cloth with lukewarm water and mild dish soap. Rinse with cool water and dry. Use light pressure: rubbing hard changes the satin sheen of the surface.
Stubborn soil, grease or adhesive: Palram approves, at room temperature, methyl, ethyl, butyl and isopropyl alcohol; heptane, hexane, petroleum ether and VM&P naphtha; and Brillianize, Klear to Sea and Simple Green. Rinse right after. On an enclosure, keep any alcohol off the neighbouring acrylic.
Foam PVC: the smooth face is a thin skin over closed cells. Clean the face only, and never scrub a cut edge, where the open cells soak up dirt and liquid.
Never use on PVC
- Acetone, MEK, cyclohexanone, THF: the solvents in PVC primer and cement
- Lacquer thinner, paint thinner blends, toluene, xylene
- Chlorinated solvents
- High-pH cleaners, degreasers, strong acids
- Abrasive cleaners, scouring pads, sharp tools
Why PVC softens. The ketones and ethers that dissolve PVC are the same ones PVC pipe cement uses to weld it. On a panel they leave a soft, tacky, dull patch that will not recover. Alcohols and aliphatic hydrocarbons do not dissolve PVC, which is why Palram's approved list includes them.
ACM (aluminum composite)
When you clean ACM you are cleaning paint: two thin aluminum skins bonded to a plastic core, with a factory paint finish on the face. The goal is to keep that finish intact.
Routine cleaning: the five-step routine. For heavier dirt, 3A Composites (Alucobond) recommends a 5% detergent solution, 1 part detergent to 20 parts water, applied with a soft cloth or sponge and rinsed. They rate it safe on PVDF and polyester finishes.
Grease and oil: a 1:1 mix of isopropyl alcohol and water on a lint-free cotton cloth. Rinse with a water-dampened cloth to remove the alcohol residue, then dry.
Stubborn stains: a diluted citrus cleaner. Isopropyl or denatured alcohol for stains water will not lift. Naphtha only with plenty of clean towels on hand.
Cut edges and holes: wipe them dry after cleaning. The aluminum and core are bare there.
Never use on ACM
- Acetone: 3A Composites says it must never be used as a finish cleaner
- Concentrated acids or alkalis, vinegar-based cleaners, any cleaner used undiluted
- Wire brushes, steel wool, sandpaper, rubbing compound, scouring pads
- Pressure washers
- Any cleaner on a hot panel or left to dwell
Why the finish dulls. A painted metal finish fails in two ways: abrasives cut through it to bare aluminum, and strong solvents, acids and alkalis soften or etch the resin, dulling the gloss. Heat speeds both, which is why the sheet maker says to clean cool panels and rinse right away. The industry reference is AAMA 609 & 610, the cleaning and maintenance guide for architecturally finished aluminum.
Machine-specific messes
Resin 3D printers: keep IPA away from acrylic
Isopropyl alcohol at wash-station strength (90–99%) is the most common cause of crazed and cracked acrylic in resin setups. Vapor does it too, slowly, when it is trapped in a closed chamber.
- Run wash stations and keep open IPA containers outside the enclosure, or wash with the door open.
- Never wipe the enclosure with the rag or gloves you washed parts with.
- Uncured resin drip: wear nitrile gloves, blot it with a dry cloth without smearing, then do the soap-and-water routine. Repeat until the panel no longer feels tacky. Do not leave resin sitting on acrylic.
- Resin on a polycarbonate or PVC panel can be lifted with 50/50 IPA and water, then rinsed. Not on acrylic.
Laser engravers: smoke film and viewing windows
Laser smoke leaves a yellow-brown film on interior panels and the viewing window. Warm soapy water removes it; repeat rather than scrub. For tar that stays, use VM&P naphtha on acrylic faces or 50/50 IPA on polycarbonate, then rinse.
The viewing window is a safety part. Clean it with soap, water and a soft cloth only. Never polish, sand, scrape or use scratch remover on it. Inspect it before every job. If you see a crack, crazing, a gouge, a burn or melt mark, or discoloration, stop using the laser and replace the window. Contact us for a replacement.
Keep cleaners out of exhaust ports, fans and filter housings.
UV printers: ink mist
Ink mist settles as a tacky film. Wipe it with the soap routine while it is still uncured. Cured ink on polycarbonate or PVC comes off with VM&P naphtha or isopropyl alcohol, then a rinse. On acrylic, use naphtha on the face only. Do not use the printer's own ink-flush or head-cleaning fluid on the panels: those are solvent blends made for print heads, not for plastic.
FDM 3D printers: dust and acetone
FDM enclosures mostly collect dust and filament strands, and the routine handles them. Let a heated chamber cool before cleaning. Never acetone-vapor-smooth ABS or ASA parts inside the enclosure: acetone vapor attacks acrylic, polycarbonate and PVC alike.
Hardware, film, heat and damage
Binding posts and screws: snug, never cranked. An over-tightened post puts the edge of its hole under tension, and that is exactly where a cleaner starts a crack. Check that posts are snug after a deep clean; do not tighten them further.
Printed brackets, hinges, latches, handles and TPU grommets: soap and water only. Dry magnets and metal hinge pins after washing.
Masking film: peel it once the enclosure is assembled. Film left on in sun or heat bonds to the sheet. To lift leftover adhesive, use VM&P naphtha on acrylic faces, or isopropyl alcohol on polycarbonate and PVC, then wash.
Heat and sun: keep the enclosure out of direct sun and away from heaters. Acrylic can distort when held above about 100 °F (38 °C) in the sun, and every cleaner works harder on a warm panel. Store spare panels flat, still masked, away from sunlight.
If a panel is damaged: crazing and chemical clouding are permanent and do not clean off. Stop using the product that caused it, note what it was, and send us a photo with your order number. Replacement panels are cut from the same files as your original.
