Diagnosed issue via video inspection (non-warranty: environmental factors)

Shipped cleaning kit including:

Microfiber vacuum attachments

pH-neutral cleaner (compatible with PVC coating)

Eraser sticks for spot treatment

Conducted Zoom training for maintenance team

Resolution Steps:

Dry cleaning: Compressed air at 0.3MPa pressure removed surface particulates

Spot treatment: Graphite smudges erased with provided rubber tools

Preventative measure: Recommended quarterly dry cleaning schedule

Outcome: Fabric restored to 98% light transmission. Client avoided $12,000 replacement costs. As the project manager noted: "We initially chose this roller blinds fabric for its 5% openness, but LEAPKA's support proved equally valuable."

Proactive Maintenance Tips for Desert Climates:

Avoid water cleaning (mineral deposits worsen dust adhesion)

Never use abrasive tools (preserve PVC coating)

Schedule professional inspections before sandstorm seasons
