White carpet looks wonderful when installed, but years of dirt and stains—no matter how much you vacuum—can leave it looking dingier than Day 1. Rather than rip out your pricey plush flooring and start all over, consider giving your carpet pile a DIY dye job. The expansive selection at AmeriColor Carpet Dyes and Chemicals offers more than 70 colors to choose from (which can be diluted to lighter or concentrated to darker shades, depending on your preferences). With a single 20-ounce bottle and guidance from our how-to, you can refresh up to 1,000 square feet! Available at Americolordyes.com; $26.95 for 20 oz.
