How to Safely Clean Surface Stains on GRC Decorative Panels? Qinglong GRC Cleaning and Maintenance Guide

Cleaning stains on the surface of GRC decorative panels requires selecting cleaning agents based on the type of stain. For neutral stains, use cleaning agents with a pH of 6-8; for acidic stains, use alkaline cleaning agents (pH 8-10); for oily stains, use solvent-based cleaning agents. Cleaning pressure should be ≤0.3MPa and water temperature ≤40℃ to avoid damaging the surface.

Actual cleaning cases show that ordinary dust can be rinsed off with water; rust stains need to be treated with oxalic acid solution (3% concentration); oil stains require special cleaning agents.
