So I get a call from a potential client stated she had a gallon or more of water spilt in the rear of her van. The majority went on the floor mats. She vacuumed and dried what she could, but is however worried that the water penetrated into the pad below and a mildew smell occurring on a hot day. I have been asked to take a look at it and see what I can do. My first thoughts are to use Carpet and Upholstery cleaner and the hot water extractor that I own. Any other thoughts? Thanks.
