How much time a steamer can save you really just depends on the condition of the vehicle. For instance, you probably won't save very much time on a vehicle that is only 6 months old and is in good shape. While a know "good shape" is a relative term, I mean a vehicle that has very little visible stains in carpets, very little "gunk" in the nooks and crannies ect. You know the kind of vehicle I'm talking about...the creme puff details as I like to call them. On the other hand, a steamer can reduce times by 25%-45% on interiors that are in average or below average condition. A majority of my details fall within this category with vehicles being everyday drivers that are anywhere from 2-5 years old, only detailed maybe once or twice a year, and that also have kids and pets that ride in the vehicles. In other words, your typical dare I say "run of the mill" type of car or SUV. And not only will the steamer save you time on these type of jobs, but it makes it much easier work to complete while giving you very high quality results.
