We’ve created our own maintenance monster, in a sense, because today’s carpets are masters of disguise. The intricate patterns mask soiling and stains.The advanced fibers and backings are engineered to resist crushing and fluid absorption.New dying techniques ensure that carpet colors stay bright, vibrant and colorfast.Yarn treatments applied during manufacturing and even some after-market treatments, effectively repel stains. All this can create a false sense of security. That’s because despite the latest manufacturing technology and can’t-see-the-stain visuals,carpets still need regular maintenance to look their best.Well maintained carpets are a good reflection on everybody who touches them:
