Every time you wipe your shoes on a common doormat, you could be stepping into a reservoir of microbial growth. Think of it as a "convention" of nasty grime at your doorstep. Dr. Doormat is the first antimicrobial treated doormat designed for the home. This is a must-have utility mat for all seasons. The antimicrobial formula is infused deep into the yarn of the doormat creating a positive charge that inhibits the growth of bacterial odors. The nasties are negative. By wiping at least twice you can trap the nasties in the yarn and zap the grime removing up to 90% of debris and keeping your home clean. You'll want to position Dr. Doormat at every entrance, ready for action. The many uses for Dr. Doormat beyond the front door: garage, mud room, kitchen sink, baby nursery, doggie door, dog crate, cat litter box, college dorm, bottom of staircase, basement entrance, patio and kitchen door, office.
