1. The causes and conditions of pollution and rust on light guardrails vary greatly from one situation to another, thus requiring repair methods that are suitable for each specific condition.

2. When using cleaning solutions for removing pollution and rust from light guardrails, please perform a localized test beforehand."Trial wipe"To confirm the cleaning effect, perform the test. If the results are satisfactory, proceed with the cleaning method. Ensure not to clean only the contaminated and rusty areas; try to clean the surrounding areas as well. Otherwise, the stainless steel surface may become uneven in shine, resulting in an unappealing appearance.

3. After using the cleaning solution, it must be thoroughly rinsed with clean water. Be careful not to leave any residue on the stainless steel surface, as this may cause rusting. Additionally, the cleaning solution may cause roughness or rashes on the hands. Therefore, please wear rubber gloves before using.

4. When using brooms made of cloth, loofah, nylon sponge, brush hooks, or brushes, the sweeping must be done parallel to the stainless steel finish. Circular sweeping is not recommended as it's difficult to clean thoroughly and can damage the surface's glossy lines, making it unsightly. Steel sweepers, such as coarse cleaning agents or sandpaper, can remove severe stains but are generally prohibited due to their potential to damage the stainless steel surface and cause rust by adhering iron particles.
