How to Clean Scratches on Perspex (Acrylic)—And When to Replace Retail Display Stands
Perspex® (acrylic) is the workhorse material behind the majority of high-traffic retail screens, security barriers, and custom product displays on South African shop floors. It delivers pristine, glass-like clarity at a fraction of the weight while offering excellent impact resistance.
The structural trade-off is that acrylic has a softer surface than glass. Over time, it naturally accumulates micro-scratches, environmental hazing, and oily fingerprints. Left unmanaged, these minor imperfections dull the material, making your retail environment look tired, unpolished, and distracting from the merchandise itself.
This guide outlines how to safely clean Perspex, minimize light surface scratches, and determine when it is more cost-effective to replace a worn panel with a fresh, custom-fabricated display stand.
Why Acrylic Scratches (And Why Retailers Still Rely On It)
Perspex is a premium brand name for cast acrylic, an exceptionally versatile thermoplastic. In busy retail and pharmacy environments, its operational benefits far outweigh its surface sensitivity:
Vastly Safer Than Glass: It will not shatter into dangerous shards in high-traffic customer zones or near children's aisles.
Highly Lightweight: It is effortless to mount, reposition, or relocate during seasonal floor transitions.
Unmatched Design Flexibility: It easily undergoes laser cutting, line bending, and custom branding treatments to match corporate identities.
Because acrylic is naturally softer than glass, traditional dry dusting, rough paper towels, and aggressive chemical cleaners physically drag micro-debris across the surface, generating fine scratches. Fortunately, light surface wear can be polished out mechanically, while severely compromised panels can be quickly measured and swapped out for precision-cut replacements.
How to Clean Perspex Without Creating More Scratches
Preventing surface damage starts with daily merchandising maintenance. The exact cleaning habits of your floor staff can either extend the lifespan of your displays or systematically destroy their clarity.
Step 1: Use a Gentle Cleaning Solution
For routine daily maintenance, stick to a simple, highly effective formula:
Lukewarm water
A few drops of mild, non-abrasive dishwashing liquid
Mix gently and apply using light pressure. For high-end cosmetic counters or intense customer-touch zones, utilize a specialized, purpose-made anti-static acrylic cleaner. These formulations leave a microscopic barrier that actively repels dust and minimizes fingerprint smudges.
Step 2: Ban Harsh Window Chemicals
Never treat acrylic like glass. Heavy-duty chemicals designed for architectural windows will permanently damage a thermoplastic panel. Strictly avoid:
Ammonia-based window sprays
Acetone, paint thinners, and strong industrial solvents
Abrasive cream cleansers or scouring powders
These aggressive compounds attack the polymer bonds, causing chemical clouding, severe brittleness, and micro-cracking—a destructive process known in fabrication as crazing. If medical sanitization is mandatory, use a highly diluted, material-
safe alcohol solution, wipe gently, and rinse immediately with clean water.
Step 3: Switch to Soft Microfiber Materials
Always use a clean, thoroughly damp microfiber cloth.
Rinse away loose grit or dust with clean water before wiping down the surface.
Wipe in gentle, straight, overlapping paths rather than scrubbing in aggressive circles.
🚫 Banned Materials: Never allow floor staff to use paper towels, coarse shop rags, or dry feather dusters. These materials act like fine sandpaper, locking in surface grit and micro-scratching the plastic with every pass.
How to Handle Existing Scratches
If your retail displays are already showing signs of surface wear, execute a quick visual assessment to determine if the panel can be salvaged or if it requires a complete fabrication replacement.
1. The Fingernail Test
Run a clean fingernail gently across the scratch:
Light Surface Scratches: You can see the mark under direct lighting, but your nail glides smoothly over it without catching. These can generally be restored through careful polishing.
Deep Scratches or Gouges: Your fingernail catches firmly in the groove, the scratch appears white, and it physically distorts the view of the product behind it. For customer-facing, premium merchandise areas, structural replacement is recommended.
2. Wet-Sanding Light Scratches (For Maintenance Teams)
For superficial surface damage on non-critical display zones, your maintenance team can attempt a targeted wet-sanding restoration:
Clean the panel completely with mild soapy water to remove all surface grit.
Procure high-quality, ultra-fine wet-and-dry sandpaper (start at 800 grit, moving up to 1500 grit).
Always sand wet. Continually dip the paper into water mixed with a few drops of dishwashing liquid to act as a lubricant.
Sand with incredibly light pressure in tight, circular motions. The area will initially develop a fine, uniform matte haze—this is normal and indicates the surrounding surface is being leveled down to the depth of the scratch.
3. Buffing Back to Pristine Clarity
Once the scratch has been leveled out:
Rinse the section thoroughly and dry with a clean microfiber cloth.
Apply a premium, acrylic-safe polishing compound or plastic restorer to the hazed area.
Using a variable, low-speed mechanical polisher fitted with a soft foam pad (or via steady manual rubbing), buff the compound using light, fluid strokes.
Monitor your progress closely. Avoid building up friction heat, as excessive heat will cause optical distortion or heat-warping in the thermoplastic sheet.
Quick Decision Matrix: Repair vs. Replace
In commercial retail, labor time carries a distinct financial cost. Spending hours of manual labor attempting to salvage a severely compromised or deeply gouged sheet of plastic is frequently more expensive than purchasing a brand-new, precision-cut unit.

Storewide Merchandising Best Practices
Maintaining pristine, clear retail displays is directly linked to store profitability. Middle-to-high-income shoppers instinctively associate flawless, highly polished surfaces with premium product quality, hygiene, and organizational trust.
Deploy Standardized Cleaning Checklists: Transition away from informal cleaning habits. Provide floor staff with a clear, laminated shift checklist detailing exactly which microfiber cloths and mild solutions are approved for acrylic counters, cosmetic risers, and point-of-sale sneeze guards.
Train Against Friction Damage: Ensure every team member knows that rubbing a dry display or using standard ammonia window sprays is strictly forbidden.
Protect Branded Graphics: When wiping down displays featuring direct UV-printed logos or promotional decals, avoid harsh scrubbing over the printed boundaries to prevent edge-peeling.
Optimize Display Stock Volumes: Avoid overcrowding acrylic steps and tiered risers. Overloading displays causes products to tumble when a consumer reaches for an item, resulting in preventable impact scratches on the bases.
Procuring Custom Replacements in Gauteng
When a display unit has run its course, moving to professional acrylic fabrication gives your brand complete control over material performance and aesthetic impact.
Modern commercial displays are engineered using tiered material thicknesses to maximize rigidity while containing fabrication costs:
2–3 mm Acrylic: Ideal for lightweight ticket holders, menu stands, and data strips.
4–6 mm Acrylic: The standard specification for rigid countertop trays, tiered cosmetic risers, and product glorifiers.
8–10 mm+ Acrylic: Reserved for heavy structural display plinths, lockable cabinets, and high-impact security dividers.
By partnering with a dedicated Johannesburg fabricator like Moriah Plastics, your team can leverage precise Laser Cutting for flawless, glass-smooth flame edges on detailed components, alongside robust CNC Routing for heavy structural foundations and interlocking joints.
Furthermore, you can utilize in-house Laser Engraving to etch permanent logos, regulatory text, or measurement metrics directly into the core of the plastic. Unlike vinyl stickers, engraved branding will never peel, fray, or degrade under daily cleaning cycles.
