We strongly recommend opting for felt rugs. Because, it is made from bamboo, grass, jute, cotton, wool, or rugs with smooth, thin plastic padding.

It reduces scratches and chemical reactions between rugs and laminate flooring. Bearing this in mind, you should avoid rubber or latex-padded rugs with colored dyes.

You can opt for rugs with padding made out of natural rubber because they don’t have colored dyes. But it would be completely safe if you avoid rubberized rugs.

Addressing the Spills on the Rug

Rugs can absorb mishaps or spills on the rug, eventually settling at the bottom. When the laminate floor contacts the rug, a chemical reaction occurs. And it can be very dangerous.

  2. Second, it would be wise to focus light on areas that have been affected recently.
  3. Finally, excess UV rays increase discoloration so it is best to reduce them.

Sunlight works like a natural color booster, keeping your floor looking lively.

Vacuuming and Sweeping

Maintain laminate floors by vacuuming and sweeping regularly to remove dirt and debris. It is possible to cause scratches on laminate flooring by both dirt and debris.

Regular sweeping and vacuuming keep things clean and prevent potential damage.

Uninstalling and replacing the old discolored plank would be the best option. Because it will transform the uniform aesthetic look of your laminate floor.
