Office Chair Scratches Tiles

The scratches on tiles caused by office chairs are mainly related to the material of the wheels, and the repair method should be selected according to the degree of the scratches.

The key factor for office chairs scratching tiles lies in the wheel material. Hard plastic wheels (such as PP/PU hard wheels) are hard, smooth on the surface but lack elasticity. When rolling on tiles for a long time, they are prone to trapping sand or dust. Under pressure, they generate friction on the tile surface, leaving fine scratches, which are especially noticeable on light-colored tiles. In contrast, soft PU wheels (polyurethane-wrapped wheels) are covered with a soft material on the outer layer. When rolling, they have a gentle contact with the ground, effectively dispersing pressure, reducing the risk of scratches, and offering better noise reduction.

If the tiles have been scratched, the repair method should be selected according to the degree of the scratches:

• Slight surface black marks or shallow scratches: Mix baking soda with water in a 2:1 ratio to form a paste. Dip a soft cloth into it and gently rub in a circular motion for 1-2 minutes. Use the mild abrasiveness of baking soda to remove surface stains, then rinse with water and dry. Alternatively, apply toothpaste to the scratches. The abrasives in the toothpaste can help fade the marks. Gently wipe with a clean cloth until the marks fade.
• Deeper or stubborn scratches: Try using industrial caustic soda. Dissolve it in water thoroughly, wait a moment, and then wipe the scratched area with a towel. Use the corrosive property of the alkaline substance to remove deep-seated stains. Or use oxalic acid to wipe. Oxalic acid can react with the metal oxides on the tile surface to dissolve stubborn scratches. However, be careful to avoid splashing it on the skin or eyes, and wear gloves during operation.
• Cover-up or beautification treatment: If the scratches are difficult to completely remove, you can choose nail polish or paint in a color similar to the tiles and apply it evenly to the scratched area. After it dries, it will cover the marks. Or wax the tiles. The wax can fill in small gaps, making the scratches less noticeable. At the same time, it makes the tile surface smoother and enhances its stain resistance.

In addition, gently scrub the scratched area with a mixture of five-cleaning powder or abrasive cleaner and water. After scrubbing it off, wipe the tile surface with polishing wax to restore its original appearance. Before using any cleaning or treatment agent, it is advisable to test it on a small, inconspicuous area first to ensure that it will not cause further damage to the tiles.
