If you are cleaning your carpet by the extraction method, then using a good carpet prespray should be the first thing to use after vacuuming. To take it a step further, using an enzymed fortified carpet prespray will help break down the dirt even further so that the extraction process will remove more dirt.
One of the best carpet presprays I have ever used is called Sledge Hammer. It is a concentrated enzyme fortified prespray that is especially effective in areas that are soiled with food and drink type products. Excellent for cafeterias, meeting rooms, hotel rooms, offices and lobbies. The enzyme activity continues digesting food based stains and odors. Phosphate free. Using Sledge Hammer will result in cleaner carpets; reduced over-wetting and the carpet will dry faster.
