Professional GRC Surface Cleaning Technology — Qinglong GRC Cleaning and Maintenance Solution

GRC surface cleaning requires differentiated approaches based on the type of contamination. For ordinary dust, use a pH-neutral cleaner (concentration ≤3%) at a washing pressure of 0.3-0.5MPa; for oil stains, use an emulsifying cleaning agent; for mildew spots, treat with an anti-mildew agent; for rust marks, use a dedicated rust remover. The cleaning procedure recommended by Qinglong GRC: pre-wet with clean water → spray the cleaner → scrub with a soft brush → rinse with clean water → air dry naturally, avoiding direct high-pressure water jetting throughout the process.

Cleaning parameters: water temperature 20-40℃, pressure ≤5MPa, contact time 5-10 minutes, rinsing at a 45° oblique angle. A commercial building's GRC curtain wall using the Qinglong GRC cleaning solution has remained as good as new after ten years, with surface contamination ≤5%, far below the 15% required by the standard.

Dust Cleaning Techniques

Dry cleaning: collect surface dust with vacuum equipment; wet cleaning: wipe with a neutral cleaner and soft cloth; special areas: clean crevices in detail with small tools. Choose the method based on the degree of dust adhesion.

Stubborn Stain Treatment

Oil contamination: emulsify and decompose with surfactants; adhesive residue: soften and remove with a dedicated adhesive remover; pen marks and graffiti: treat with targeted solvent-based cleaners; biological contamination: remove thoroughly with biodegrading agents. Targeted treatment ensures effectiveness.

Special Contamination Removal

Rust contamination: remove through reaction with an acidic rust remover; calcified deposits: dissolve with a weak acid solution; smoke contamination: remove by encapsulation with adsorptive cleaners; graffiti: penetrate and decompose with a dedicated cleaning agent. Professional agents are safe and effective.

Cleaning Precautions

Avoid direct high-pressure water jetting to prevent surface damage; keep acidic cleaner concentration ≤3% to prevent corrosion; rinse thoroughly after cleaning to prevent residue; work in a shaded environment to prevent rapid drying. Standardized operation ensures safety.

Professional cleaning preserves aesthetics. With Qinglong GRC's comprehensive solutions, GRC stays looking new over time.
