And finally, I didn't forget, those pesky flat spots on the carpet where the furniture sits. Sometimes, if there is a heavy pattern in the area rug, it can go unoticed. But if the carpet is a sold colour, the dents will be much more obvious. Place ice cubes on the indented areas and let them melt. Once they are gone, give the rug a once over with the vacuum and the fibers should pop right back up. In some cases where the furniture has been sitting for extended periods, you may need to repeat this process a couple of times.
