Unlike LCD TVs, projectors can cast images on screens, white walls, desktops, and even special surfaces like water curtains or rockeries. However, only with a clean screen can you enjoy 4K-level delicate picture quality. Whether it’s juice stains from kids in home theaters or coffee spills in meeting rooms, screen dirt can easily ruin viewing and working experiences. As a professional team specializing in custom projection screens, we’ve compiled this practical cleaning guide based on the latest 2025 screen material characteristics, plus Q&A to help you maintain your screen easily.
1. Scene-Specific Stain Removal: Target the Right Solution
Stain types vary greatly across scenarios, and blind cleaning will only make things worse. Here are solutions for three high-frequency scenarios:
- Home Theater : Snack crumbs, pet hair, and juice stains are most common. Use a soft brush or silicone air blower to remove dry debris first , then treat liquid stains like juice with neutral detergent.
- Office Meeting : Coffee stains and marker marks are major nuisances. Blot fresh coffee stains immediately with a dry microfiber cloth, then wipe with diluted neutral foam cleaner; use a pure white high-quality eraser to gently remove marker marks without damaging the coating.
- Event Performance : Stubborn stains like color spray and oil are the hardest to handle. Currently, there’s no effective way to clean color spray stains, so it’s best to retract retractable screens before events. For oil stains, use a cotton ball dipped in a small amount of degreasing solvent to fade them quickly, then dilute residues with pure water and blot dry .
2. Material-Specific Cleaning Guide: Covering 2025 Mainstream Screens
The 2025 mainstream screen materials have expanded to 7 types, with significant differences in cleaning taboos. This table clarifies everything:
| Screen Material | Cleanability | Recommended Tools | Absolute Taboos | Custom Scenario |
|---|---|---|---|---|
| White Plastic | ★★★★☆ | Microfiber Cloth, Neutral Detergent | Oily Detergent | Entry-level Home, Classroom |
| White/Gray Glass Fiber | ★★★★☆ | Polymer Sponge, Silicone Blower | Hard Brush, Alcohol | Mid-to-high End Home Theater |
| Metal | ★★★☆☆ | Dust-free Cloth, Pure Water | Organic Solvents, Hard Contact | Business Display, 3D Viewing |
| Glass Beaded | ★☆☆☆☆ | Feather Duster (Light Brushing) | Any Liquid, Wiping | Budget Temporary Venues |
| Anti-light (Black Grid) | ★★☆☆☆ | Special Cleaning Wipes | Water Soaking, Coating Rubbing | Bright Living Room, Open Space |
| Acoustic Transparent | ★★☆☆☆ | Soft Brush, Low-power Vacuum | Liquid Detergent, Pressing | Professional AV Room |
| Photon Screen | ★☆☆☆☆ | Dry Dust-free Cloth (Light Wipe) | Any Detergent, Wet Tools | High-end Private Theater |
Special Note: Due to the porous structure of the quartz coating on glass beaded screens, stains cannot be removed once penetrated. Daily maintenance only involves light dusting with a feather duster, and the screen must be retracted when not in use . Glass fiber screens, popular in 2025 for their wrinkle resistance and easy cleaning, have become the top choice for home customization .
3. Tool Upgrade: 2025 Professional Cleaning Kit
Traditional cleaning tools can hardly adapt to new screen coatings. These 2025 mainstream tools significantly reduce cleaning risks:
- Core Tools: Microfiber dust-free nano cloth (fiber diameter only 0.1μm, avoiding coating scratches) and degradable neutral foam cleaner (pH 7.0±0.5, suitable for resin and rubber substrates) .
- Auxiliary Tools: Electric brush roller (dusting before cleaning, suitable for acoustic transparent screen gaps) and lint-free cotton balls (treating local oil stains with minimal fiber residue) .
- Warning: Avoid brightening cleaners，whose ingredients form a reflective film on the screen surface, seriously affecting picture quality. Rough towels will damage the honeycomb structure of metal screens, reducing gain.
4. Q&A: Have You Fallen for These Traps?
Q1: Why does the picture become blurrier after cleaning?
A: It’s probably due to detergent residue or wrong tool selection. Non-volatile detergents cause light refraction disorders when moisture penetrates the coating. Switch to volatile foam cleaners and blot residues with a dry cloth—especially ensure metal screens are completely dry before use.
Q2: How to prevent mold on fixed frame screens that can’t be retracted?
A: Fixed frame screens are prone to mold in humid environments. Use a dehumidifier in damp areas (maintain 40%-60% humidity) and dust with a soft brush monthly. For mold spots, gently wipe with diluted neutral detergent and dry with a distant hair dryer .
Q3: Can anti-stain treatment be applied during custom screen production?
A: Absolutely! We offer custom anti-stain coating services for special scenarios like restaurants and kids’ rooms. The nano-protective layer reduces stain penetration, and the wipeable material simplifies daily cleaning.
5. Ultimate Tip: Maintenance Matters More Than Cleaning
No cleaning skill beats daily protection: Retract electric screens within 5 minutes per use to avoid motor overheating affecting sealing ; Wipe oil fumes off screens near open kitchens regularly and opt for oil-resistant coatings; Choose retractable electric screens for commercial use to reduce contamination when idle.
Material adaptability is key when customizing screens—we recommend optimal materials based on your scenario (home/commercial, bright/dim) to minimize cleaning efforts. After all, a low-maintenance screen ensures perfect projection every time.
