I live in a condo and the carpet has a lot of dark spots, looks like are old stains that never goes away. What is the best and cheapest way to clean it? or is better to recolor the carpet?
Answer: You should begin by pre treating your heavy traffic areas with Tough Stain Pre-Treat for Carpet and Upholstery for 10 minutes. Then, use your BISSELL portable or upright deep cleaner over the affected area. Try drying your carpets with a fan blowing on it, once dry if the stain remains, treat with OxyPro® Stain Remover for Carpet and let it work until it dries on its own.
