I moved a few weeks ago. After the movers took my furniture, I was left with dozens of furniture marks in the carpet. I used an old toothbrush and rubbed against the grain of the pressed down carpeting. With a little effort, I was able to greatly improve the appearance of the carpeting. (I didn’t have any ice cubes in the house or I would have tried a technique I learnt from Pinterest.) However, I was pleased with my results.
