The best method for sterilizing carpet without hiring a professional is to mist the surface of the carpet with a mixture of white vinegar diluted with water and allow it to sit overnight. Then you can steam clean your carpet using the manufacturer's instructions on your machine.

Thoroughly Rinse Out the Carpet Dedicate enough cleaning and rinsing time, especially if it's fluffy or heavily soiled.

Under suitable conditions, your carpet should be dry and ready to walk on by the afternoon. Most carpets generally take about six to eight to dry completely after cleaning. Regardless, several factors affect how long it will take for your carpet to dry.

In a bowl or small bucket, mix one part white vinegar with three parts water. Dip the bristles of the scrub brush into the solution and rub them into the carpet. Massage them into the fibers well (without fully saturating the carpet) and follow up with a cloth to help blot excess moisture.
